These circuit devices can be connected to other digital circuits, for example digital switching circuits. used in data processing systems, microcomputers, etc., as well as in . In these circuit devices, the information transmission channel called the bus is connected to the central processing unit.

vanguard return According to the prior art, information is mostly dedicated via electrical connections within individual circuit devices. It is transmitted electrically. Components such as CPtJ module, memory module, etc. For computer modules, parallel data or address words The processing is adapted so that the information transfer channels or busbars are parallel printed conductor systems. For example, a 16-bit word cannot be stored in a microprocessor. When processing with a sensor, 64 or more lead wires are required.

Therefore, when time division multiplexing is performed, the data words and the number of busbars in that the address words are transported by the same number of lines. Attempts are being made to reduce it. For small systems, design the busbars in series. and reduce it to two lines (data line and timing line). However, Assuming that the multiplex processing has the same processing speed, the bus signal However, such multiplex processing requires There is a limit.

Printed conductors as well as the resulting contact devices for plug-in modules The costs resulting from the parallel guidance of do not have. Digital circuit devices are currently manufactured using circuit board technology. of the components Considering the topology of the individual busbars caused by the arrangement, and also the flexibility of the overall system. Therefore, compensation must be made for line uniformity and characteristic impedance. Therefore, it is necessary to compensate for termination based on the characteristic impedance of the busbar. There must be. Improper shielding results with respect to adjacent printed conductors The resulting disturbances and effects are limited to the available bandwidth for most busbars required. In the case of microcomputers that perform high-level calculation processing, busbars Reduce channel burden.

For the reasons listed below, for example, forming a busbar in a circuit device using an optical transmission path To date, no consideration has been given to the replacement of tangent @ lines. star coupler Today's information on glass fibers such as ring systems with repeaters or T-structures Up until now, the known connection principles either limited the number of connectable circuits from the beginning or restricted the movement of signals. Limit data output and response time due to increased frequency. Moreover, for example, Produce removable couplings on fiberglass to various circuits at an acceptable cost. unable to produce.

Therefore, to date, the actual proposals for optical information communication have been based on sub-system distances of 10 to 10. Limited to interconnecting very large multi-processor systems at 100 m. It does not extend to connecting individual components on a circuit board.

Mizuyu beans two Rijo The problem with the present invention is that the individual circuits can be connected by optical busbars. The purpose of this invention is to further develop the circuit device according to the preamble.

According to the present invention, this problem can be solved by the features given in the characterizing part of paragraph 1) of the claim. It is resolved by the symptoms. According to the invention, the known light guide system relies on the principle of total internal reflection. It is recognized that the Ta. Accordingly, the present invention provides an external circuit on which individual circuits are arranged and in the form of an optical circuit board. A boundary material with random complex reflectance on the surface, i.e. a highly absorbing boundary material, is suitable. Provide a circuit board for use in These interface materials are compatible with known light guide systems. No related considerations have been made.

However, according to the present invention, there is no need to respect specific angle conditions, etc. The introduction and extraction of light through such boundary materials, that is, the range commonly used for communications. It has also been recognized that electromagnetic waves in the near-ultraviolet to infrared range are possible in an extremely simple manner. recognized. The imaginary part is preferably larger than the real part. As a result of the complex reflectance, reflection is possible at the outer surface under all angles of incidence.

As a result, the circuit can be easily connected to the optical circuit board described in claim 1). . For coupling purposes only electro-optical and photo-electric conversion elements are required. boundary material These are arranged in binding windows within the material.

Naturally, parallel transmission of both or one of the data signal and address signal is possible on the optical bus. It is Noh. The difference between the individual bits of information transmitted in parallel can be determined by e.g. suitable modulation or can be configured with different wavelengths (color separation), in which case parallel data The name ``dot'' has already combined electrical-optical and optical-electrical conversion elements. .

A particularly simple construction of the circuit arrangement with an optical busbar according to the invention is defined in claim 2). In that case, the information transmission on the optical bus is done in a linear manner and Linear transmission rates of 500 to approximately 600 mbits/sec can be achieved with the 2000 mbit/s code. Book The optical circuit board according to the invention enables transmission rates of several nine bits per second or more, thus surpassing current practice. Not only is it possible to couple a practical transmission rate with linear transmission, but in fact, the transmission rate can be considerably accelerated.

Claim 3) provides that an electrical-optical and optical-electrical conversion element is provided in the notch in the boundary material. A particularly simple connection of the individual circuits to be installed is described. Claim No. 4) In the case of the devices described in items 1 to 16), the degree of connection, that is, the connection and disconnection of light The efficiency of can be increased.

Allows connections to individual circuit boards in a computer made up of boards or terminal equipment. It is compatible with the high transmission speeds that can be obtained within optical carriers for various locations.

Claim 13) claims for easy and inexpensive connection of glass fiber cables. ing.

The electrical energy required for the operation of individual circuits can be transmitted through optical busbars. Of course. (In the case of large circuit boards or circuits with high energy consumption, It is becoming increasingly important to provide electrical conductors on optical circuit boards that can supply electrical energy to various circuits. These conductive strips are added to eliminate wasting heat generated in the circuit. can be used.

Different types of optical circuit boards used for signal input and output.

The switching element can be constructed as a separate component, on which e.g. A commercially available integrated circuit can be implemented in a standard casing, e.g. can be accumulated within the “base”. However, in a preferred embodiment, the transducer is, for example, an IC card. integrated circuits, such as CPU circuits, etc. 16) and 17)) Constructed behind the silicone kneebar. It will be done.

The structure of the optical circuit board according to the present invention allows easy connection and disconnection of coupled light. It is possible to detachably attach a circuit to an optical circuit board without incurring considerable expense.

As a result, standardized optical circuits for different circuits can also be achieved through linear signal transmission. Using road plates, different circuits can be implemented on individual “plug-in points” Becomes Noh.

How to prepare and plate FIG. 1 shows an embodiment of a circuit arrangement according to the invention, in which a circuit 7 is arranged on a circuit board 1. The circuit board is composed of an optical circuit board having a reflectance n1, and the optical circuit board has a reflectance of n1. Either side is coated with material 2 (hereinafter referred to as material), and the material is complex reflectance n2 = n2 (1-jk), where the real part n2 is preferably It is preferable that the reflectance n1 of the optical circuit board 1 be smaller than that of the optical circuit board 1.

The interface material 2 has a cutout 3 which serves as a coupling window for connecting the electro-optical converter 4 and the optical - Enable input and output of optical signals relative to the optical circuit board by electrical converter 5; .

The individual converters 4 and 5 are in each case a component of a circuit 7, which circuit also comprises: Commercially available (mechanical) circuits 6, e.g. CPU and electrical energy source It has a lead wire 8 for it. Electrical energy can be supplied by a wide conductive piece 9. Yes, the conductive piece is applied to the boundary material 2 or if a metallic boundary material is used, the light The circuit board 1 is made of, for example, optical glass or a plastic material customarily used for optical purposes. , such as those sold under the trademark CR39. light is a A 0.5 μm coating of aluminum may be included, and for stability reasons such coating may is provided with a 5 μm copper coating.

In a preferred embodiment of the invention, the boundary material 2 can be guided into the suction circuit board 1. . The reflection within the boundary material 2 is in this case essentially null as a function of polar direction and angle of incidence. However, the blocking of light is low due to the limited absorption of the material of the optical circuit board 1. Therefore, the interface of material 2 (e.g. metals such as AQ, AI, CLJ) is used. By appropriately selecting the wavelength of the light beam and the thickness d of the optical circuit board 1, no difficulty can be solved. Replace the circuit board up to the so-called European tentative dimensions of, for example, 100 x 160 m without can. Therefore, the optimal plate thickness between 2M and 48 as a function of parameter selection is obtained for the optical signal pulse energy, i.e. compared to the wavelength of the light used. In this case, a large plate thickness d can be obtained. The optical circuit board 1 having such a thickness is also suitable for Due to its reasonable mechanical stability, the circuit board can be mounted without additional support mechanisms. It can be installed within the facility.

The electro-optical converter 4 is a random converter, for example a wavelength range used for optical communication; In other words, light emitting diodes (LE'D) and semiconductors that provide light in the range from near ultraviolet to infrared light. It can be configured with a body laser, etc. Correspondingly, the optical-to-electrical converter 5 receives such optical signals. It can be a random converter that can convert signals into electrical signals. For example, photo-electric The gas transducer 5 is a commercially available diode, preferably a planar diode for cost reasons. Can be configured with photo diodes.

Transducers 4 and 5 are preferably integrated together with circuit 6 and terminals 8 in a common housing. However, it is only possible to use separate housings for the converter, perhaps a parallel-to-series converter. For example, a commercial chip can be implemented on the housing to act as a functional module. Of course, it can also be worn.

When the bars communicate with each other, the individual notches 3 or coupling windows are arranged in such a way that they do not shade each other, i.e. randomly between the two bonding windows. There is no third bond window on the extending bond line, and this is a bond window on one or both sides. Applies to both arrays.

FIG. 2 shows a detailed part of the circuit arrangement according to the invention which is schematically represented in FIG.

The structure shown in FIG. 1. For example, a singularity based on that according to DIN 66264 can be used. circuit What is an IC, for example, a CPU with a parallel structure for the data bus and address bus? Separately, the active bus subscriber 11 is a parallel-to-series converter '16 (PSU ), a receiving amplifier 20 having a transmitting amplifier 19 and a signal scanning circuit 11. .

In that case, the bus subscriber issues a timing with respect to the transmission timing 24. generator 12, which is a timing divider (counter) with a fixed division ratio 1/n. The processor system timing 14 is generated by the processor 23. Black A clock generator 12 also provides scanning intervals to the signal scanner 11. Parallel-Direct Column converter 16 serially converts the parallel data words obtained in internal registers. and reconversion following transmission.

In the case of passive bus subscriber 22, the random number is the address of the active subscriber. connectable within the range of possibilities, which means, for example, that random internal components ・Includes an access memory 18 and again includes a receive amplifier 20 and a transmit amplifier 19 , for the internal parallel structure represented by the internal parallel bus 15, the parallel-to-series converter 16 is also required. Synchronization during transmission rotates system timing from the transmitted signal. This is ensured by the timing recovery circuit 13. Parallel-series converter〒 16 also electrically or otherwise programs the active components prior to use. Contains address information that must be included.

FIG. 3 shows a pulse/time diagram of a serial transmission on an optical busbar according to the invention.

Parallel is currently used for serial transmission of microprocessor bus signals. Busbars vary widely in structure and are strongly limited to specific processor structures. Therefore, it is not possible to provide an overall useful transmission protocol. Therefore, For example, processors M6800 and M2SO4 (both from Motorola, USA) ) and R6502 and related processors (MOS, Rockwell, USA) and R6502 and related processors (MOS, Rockwell, implemented for the microprocessor bus family including GTE, etc. The serial bus protocol described below can be applied to a serial synchronous microprocessor bus system. should be considered as a possible implementation example for the system. Asynchronous series mother A line system can be derived from said busbar system in a similar manner.

From the common deadline time 31 for serial transmission, “PLL counter reading 37 signal 0 following the remaining time T RW. A synchronized overlapping two-phase timing system 40 according to FIG. Based on this, the directional signal R/W sets the logic to O for the cycle.

The address word 43 valid for dwell time TAd is passed to the parallel address bus. Therefore, starting from the address prepit (AVP > 38), the serial bus signal 46 is sent. Faith can be started earliest at this point. For this example, control signal R/W49 is included within address transport 50, which transport is an address post bit (ANB). 51 and occupies the so-called transfer time window. Combined with the transfer of control and address signals As an active bus subscriber, the processor responds to active bus cycles. Liver is H! which was established for this purpose. On 5, 11, 13, 16, 20, these signals and must evaluate them, and the subscriber in question must: Preparations for data transmission must be made.

During the second phase of the bus cycle when the operation is correct, the processor has a dwell time TDS. A data signal 4 that can be used subsequently must be created. This is a data prep The data 52 and data 53 are sequentially transferred to different transfer time windows. passive of the problem The bus subscriber receives this and then tries to convert it back to parallel form at 16 points. It corresponds to the functional memory (RAM) of ) or other actuating device (I-〇 element).

For read operations, the active bus subscriber in question is serial data word 53. is transferred to the processor, following the access time TZP, and following the end of the address transfer. We must start again with the data prepit 52. This transfer cycle is For correct operation, facilitate code logging by busbar subscribers. Preferably, it occurs in the same manner as.

Figure 4a shows an optical coupling device for LED 4 as an optical transmitter (electrical-optical converter element). Possible designs are shown in enlarged form. Transparent material preferably having a reflection coefficient n3-nl (e.g. adhesives for fixed connections or liquids for removable connections) A fixed transparent material 28 (e.g. .

Since the planar LEDs embedded in the synthetic resin are arranged in the bonding window 3, the exit surface allows input of photons generated in the active zone 29 into the light guide 1 .

The choice of anti-copper ratio n1-n3=n4 makes the coupling insignificant for example with respect to the slope, It is ensured that there are no transmission losses at the interfaces involved. Rapid converters currently available is a small active surface 30 that is compatible with the glass fiber light waveguide based on its physical structure. Mainly as a planar radiator or a planar receiver (Lampartian characteristic) with Optimized.

However, optical transmitters that operate in the same manner as Lampartian radiators are The reason is that the signal is transmitted under a partial solid angle. The proportion of radiant energy that makes the most important contribution to the total amount of irradiated light energy is Due to its relatively small size in comparison.

A useful signal base stretching that limits the transmission rate to The reflection coefficient on the boundary material 2, i.e. by selecting a material with poor reflection properties. This can be counteracted by reducing it. The process consists of small optical circuit boards (edge length can be successfully used for The additional damping is noticeable for thin optical circuit boards and increases with the distance between transmitter and receiver. If the separation is large, the degree of coupling will further deteriorate.

However, the radiant energy generated at the exit face 30 of the emitter diode At least 10 @ or more of the following can be combined. However, it is not specified As a result of the narrow radiation direction, this does not solve the pulse stretching problem.

most of the radiated energy in a symmetrical manner in terms of rotation and in a narrow solid angle range Another modification is made by means of a directional radiator that radiates a certain amount of energy and corresponds to the preferred direction for signal transmission. can do good. Beierstrass sphere (we 1erstrass- sphere> is set to W, and the radiator is transformed into a Beyer Stratsse half according to Fig. 4b. It can be created as a sphere 32, and the outer radius r1 is the buried material (na if necessary). =rll:'1.5. , 1.8> of the emitter material (GaA IAs:Ns = 3.6) is constructed relative to the inner radius r2 of the imaginary number in the same manner as use

If the required aspheric surface is presently available in the art for compounds of groups II Quite apart from the fact that it cannot be produced at an acceptable cost using state The directional effect of the It's going to be a big deal.

This drawback is related and is consequently easier to manufacture than the pie-stratuse hemisphere. Radiation characteristics of hemispherical radiator 33 (Fig. 4C) or spherical radiator for a simple partially fixed angle can be eliminated when using a radiator with only comparable radiation properties. . For the purpose of achieving the same beam focusing as the latter, the radiator 33 in FIG. Symmetrical optics 25.37 must be provided and these optics are An imaginary inner surface that partitions the active emitter surface 38 based on the structural principle of the Tuse spherical lens. radiation by selecting the ratio of the outer radius of curvature of lens 35 to curve 34. A spherical aberration-free image of the circle inside 38 of body 33 can be made possible. The radius ratio is preferably The reflectance ratio of the glass or plastic bodies 35 and 36 is the same as nt/n6. It will be done. Active radiation @ where the outer surface 37 of the main body 36 is imaged with the center of curvature without spherical aberration If the shape is defined in such a way that it is positioned on the image of 1a38, then The device of Figure 4C also works well with the layer provided that the surrounding material is homogeneous and isotropic. It has the advantage of being independent of the reflectance of the material used.

Extremely high reflectivity that is as close as possible to the reflectance of the transmitter or receiver material If the material of the optical circuit board 1 has You can also get some improvements. However, glass with high reflectance (n>2> or transparent plastics are generally very expensive and often have relatively high internal conductivity. It has a coefficient. According to Fig. 4d, only the area around the coupling window has high reflectance. 27, while if the remaining transmission medium has a low reflectivity Proportional improvements in binding factors can also be achieved.

During production, the points in question are subsequently filled with a material 27 having a high reflectivity. A notch can be provided. The resulting interface is oriented directly to the ray. are arranged at the corners, i.e. form a hemispherical surface in the case of a small active radiation surface 29 of the emitter. If this is done, the influence of the optical path can be avoided. Anti-reflection intermediate coating is provided between the light After coating the circuit board with the interface material 2 and forming the bonding window 3, a semi-liquid liquid is applied to the bonding window 3. within the circuit board 1 in such a way that a diffusing lens 54 having a continuous reflectance configuration is obtained through the By penetrating the , other realization possibilities are obtained.

Optical communication by Iga, S., Misawa, M., and Oikawa in connection with the production of diffusion lenses. Paper presented at the 9th European Conference 1 (September 19B4, Stadt) on “Plane 30 of the Minutes of ``Laminated Planar Optical System Using Micro-Lens Arrays'' Ru. If the reflectance gradient is oriented in the direction of a right-angled constant-angle trajectory, the light path is again There is no negative impact.

However, according to Figure 4e, the intensity of the emitted ray (in the case of an emitter) The path of the light is affected in such a way that the strong part hits the boundary surface 2 at a shallow angle. L=t, which both improves the coupling factor and reduces the dispersion of the pulse response of the transmission channel. If the lens 55 has a rotationally symmetrical toroidal shape, the lens 55 is placed in the coupling window 3. shall be provided. According to the two processes mentioned above, these lenses can be produced in two types. Manufactured using homogeneous materials and using a suitable annular diffusion mask according to the diffusion process. It can be made.

The above considerations apply in a similar manner to the receiver, but in this example, the Fast, wide-area PIN photodiodes with externally constant maximum efficiency are available in area technology. It exists even if

It is possible to use directional light transmitters or other coupling aids, i.e. If a coupling cone 31 is available that affects the directional action, the relative reflectance The angle of incidence at the boundary caused by the difference nl and n2 is smaller than the main radiation angle of the optical transmitter. If desired, it is also possible to use a real-valued reflectance n. For this example, the transmitted light Body angle selection results in virtually pulse stretching at the interface area , and the pulse energy from transmitter to receiver is roughly proportional to the distance. It is preferable to use mating in the case of large optical circuit boards.

Semiconductor chips with highly integrated circuits are manufactured preferentially in semiconductor technology, and one-sided It is used only in

When used within optical busbar systems, e.g. large area PIN photodiodes The back side of the chip can be used by forming a transmitter in the form of a code on the back side of the chip. It is clear that Highly integrated technology directly applies to semiconductors (III-V group compounds) Optical-to-electrical converters (e.g. LE D and photodiode) can be formed. These converters from optical circuit boards It is clear that the bottom side of the far chip and the top of the chip are mounted on top of the remaining circuit components. It is clear.

Figures 5a-5b show that the degree of coupling is increased by using a special lens shape. Each represents a different possibility of improvement.

Figures 5a to 5c show that the degree of coupling is increased by using a cylindrical lens 60. The extent to which this can be improved depends on the cylindrical lens 60 produced according to the diffusion process. It shows the possibility of realization. Following production, these two halves are assembled The separation point 61 is present because the solid cylinder is formed by the solid cylinder.

According to the diagram in FIG. If a reflection@62 is installed at the top, the light will be reflected back to the original direction of travel. , this drawback at the separation point can be eliminated. Therefore, the mirror surface of the lens If placed in the centerline, the cylindrical lens 60 can simply be designed as a half lens. is necessary. An observer ``inside the optical circuit board 1'' will notice that the final emitter 4' I think it was on the edge of the component.

Figure 5 shows a combination window and a cylindrical half lens that focuses only in one plane. A three-dimensional representation of the resulting circuit board segment is shown. These lenses are diffuse lenses, solid It can be provided within a mirror surface as a lens or a Fresnel lens. into a light converter On the other hand, if specific wavelengths are used, holographic mirror lenses can also be used. However, manufacturing this lens is currently extremely expensive for short wavelengths.

Figure 5d shows the distribution of radiant energy with the optical components positioned above the receiver surface. The possibility associated with the optical circuit board segment 1 being defocused in the plane is shown. This presentation In the embodiment shown, three bus subscribers are utilized. For each emitter, the intensity of the radiated light is subdivided into three partial solid angles. and is directed in a focused manner onto the receiver base.

However, to perform the desired energy subdivision, an asymmetric lens block is required. 65 is required. The side view of Figure 5d shows the arrangement of planar busbar subscribers. shows a circuit board segment with a tilted mirror. This is due to physical (solid lens and diffusion) lens) requires an axially symmetrical lens arrangement. However, Frey Various other shapes can be obtained by using flannel lenses or holographic lenses. Mr. Honji 1g prefers to use this kind of lens shape because it is possible to Ru. Therefore, since plastic is particularly easy to mold, it is suitable for optical circuit board 1. Plastic is a particularly suitable material for this purpose.

6a to 6C, the optical circuit board 1 is subdivided into a large number of segments 56, 57, etc. 2 shows another embodiment of a mustache device with a light busbar according to the invention; individual busbars The systems are optically isolated from each other by an opaque partition 60 so that the The systems can function completely independently of each other. Bus subscriber 59 is the first It is designed as shown in Fig. 2. A special feature with two coupling windows 3 in each case. Another bus subscriber (bus extender) 58 connects two adjacent bus sections. Make signal connections between components. Therefore, these bus subscribers The two emitters and receivers must be controlled by an integrated circuit 6 that is inserted into the receiver. Combinations 4 and 5 are provided. Partial busbar systems can be organized hierarchically Therefore, only a specific extender 57 can communicate with the remaining partial mother @56. make it possible. All adjacent partial busbars are busbar extender subscribers-5 If they are interconnected by 8, organizations with the same hierarchy can be coupled.

If the transmission system is used for switching purposes, internal considerations apply to the selection of connection paths. Only busbar extender subscribers with specific circuit designs are used. It is preferable.

Separation points (Figure 6C) are designed with an inclination angle of 45° at 62 locations, and separation If the surface is aluminized, it is possible to couple improvements to the optical coupling factor. Ru. Next, the emitter 4 and also the receiver 5 are in turn connected to the receivers of other bus subscribers. are arranged centrally through mirror inclined surfaces so that the coupling factor of the light emitter is at an optimum value.

If only busbar extenders are used, aluminum treatment of non-sloped surfaces 63 is unnecessary. Coupling factors using additional lenses according to Figures 4a to 4e can be further improved.

Figures 7a and 7b illustrate the connection of glass fibers to the optical circuit board 1 according to the invention. vinegar. This connection is made by means of glass fiber 71 to the remote connection point and the terminal subscriber. Enables good luck. These connections are similar to the reflective coating 74 as well as the diffusing lens 7. 2.73 can also be easily obtained. Special with receiver 5 and emitter 4 The bus subscriber 7 connects the optical circuit board 1 to the optical bus and a special coupling piece 75. A connection can be made between. Figure 7a shows the light emitter of bus subscriber 7. - shows the lateral connections in the receiver module, and figure 7b shows its forward connections; . Diffusion lenses are designed as spherical lenses and these lenses have a separation coating It can be made as two partial lenses with 76.

The @ rating of series bus transmission is parallel bus access time TDL - maximum (T, D, TRW) A reduced access time compared to DZP is obtained through DZP, which reduces the transmission time and correspondingly increase by subdividing the transmission cycle into more than 72 units. I can do it. However, the current state of the art is that internal parallel connections approximately 200 ns for connected active subcomponents (e.g. RA M). 1000 nS bus cycle duration Tz and in such a way that the access time remains 72 mbit/s serial transmission rate, approximately 200 TTL gate function for PSU1 6 is easy to create. Current processor gates (Iiil number and ratio) In comparison, this additional cost for serial transmission is very small.

Bus drivers in conventional parallel connection with slight changes in processor structure Particularly effective when the logic is replaced with a corresponding PSU subsystem 16 in an integrated circuit. The address signal and the You can create the residence time for control signals◎ The advantages of the optical busbar of the present invention compared to conventional circuit board technology are as follows: be.

1. Do not use or require high-value raw materials such as copper and gold for contact devices. For example, aluminum (printed conductor/cooling, aluminum use of inexpensive raw materials such as aluminum (tinium-treated), glass or plastic; This makes it possible to drastically reduce material costs.

2. In each case create a new circuit board layout for the new computer structure. instead of creating a single array of connection windows for a given number of connection points. It is simply necessary to

3. By substantially eliminating the N gas contact device, the structure page is even more dense. Implementation is possible.

4. Lower external quantitative efficiency of 3 to 5% compared to currently available light emitting devices (LEDs) With the increase in word width of computer components even when using optical transmission methods This reduces the energy dispersion in the range of the bus driver logic system.

5. Since there is no external signal printed conductor, this conductor can be transmitted through an alternating electromagnetic field. No voltage is generated. Short component lengths of chip-printed conductors that still exist The dielectric current can be compensated considerably due to excessive chip layout. There are very few The operational reliability of the components is increased.

6. Plug-in socket and removable connection for busbar subscriber at connection point For example, if a computer system is equipped with a bonding interlayer of Reconstruction can then be carried out relatively to.
