Definitions

  • the invention relates to an electrolysis system for the galvanic reinforcement of conductive pre-coated band-shaped plastic films which pass through the electrolysis belt in vertical loops, consisting of an electrolysis trough with vertical anode plates arranged parallel to the band course and drive and contacting rollers arranged at the top, and a washing and Drying plant.
  • DE-OS 15 21 076 describes a device for plating a strand of plastic, a metal layer of extremely small thickness being first produced on the plastic by chemical deposition, which is then electrolytically reinforced.
  • the precoated strand is passed in a plurality of loops through an electrolysis bath, which has an electrolysis trough parallel to the course of the strand arranged vertical anode plates and above arranged drive and contacting rollers.
  • the first three loops are kept considerably shorter than the following ones and are at different voltages, so that they can be seen as independent electrolysis cells.
  • a voltage of approximately 15 V is applied to the first drive and contacting rollers, a voltage of 5 V to the second and a voltage of 2 V to the other drive and contacting rollers.
  • the invention has for its object to provide an electrolysis system for the galvanic reinforcement of conductive pre-coated band-shaped plastic films, which manages to reduce the effort with significantly fewer loops, in particular with only one.
  • This object is achieved according to the invention in that the conductively pre-coated plastic film strip immediately before immersing in the electrolysis bath by means of a grinding cathode arrangement arranged perpendicular to the direction of movement of the plastic film strip and after the outlet from the electrolysis bath in a manner known per se by drive and Contacting rollers can be contacted and that the grinding cathodes of the grinding cathode arrangement and the drive and contacting rollers are electrically isolated from each other and connected to their own power sources.
  • rod-shaped grinding cathodes are arranged on both sides of the tape, which are arched on the side facing the plastic film tape and are arranged so that they are offset in the direction of movement of the plastic film tape and to one another Plastic foil tape passed between the two grinding cathodes successively spreads them over the entire area.
  • the current can be increased further by cooling the plastic film strip or the metal layer on and immediately after the grinding cathode arrangement and on and in front of the drive and contacting rollers.
  • the pre-coated or reinforced plastic film strip can preferably be cooled on and after the rod-shaped electrodes by compressed air and on and before the contacting rollers by bath liquid or water.
  • plastic screens are provided in a manner known per se on both sides of the plastic film strip, which, according to the invention, can be adjusted perpendicular to the direction of movement of the plastic film strip in order to adapt to the bandwidth and current density distribution. Furthermore, it has been shown that if you introduce a panel over the entire width of the plastic film strip into the bathroom from above on the inlet and / or outlet side, the current on the inlet and outlet side can be increased without the Copper layer is damaged. This aperture ensures a uniform current density distribution on the inlet and outlet side.
  • plastic foil tapes coated on one side are to be galvanically reinforced, only the corresponding grinding cathodes or contacting rollers are connected to the corresponding power sources.
  • two plastic film strips coated on one side are used according to a further proposal treated simultaneously by bringing them together so that the coated sides are on the outside. This can be achieved with only a little additional effort in that a further unwinding and winding roll is provided for the second plastic film strip.
  • Figure 1 shows in principle an electrolysis system for the galvanic reinforcement of a conductive pre-coated band-shaped plastic film.
  • a plastic film strip 1 is 2-pulled off an unwinding roller which is mounted in a wall-shaped housing part 3 and is in drive connection with a brake motor which is not visible in the drawing.
  • the brake motor ensures that a constant tension is maintained in the plastic film strip 1.
  • Via drive rollers 4 and 5, the plastic film strip 1 is fed to an electrolysis bath 6 which has a container 7 in which a pull roller 8 is rotatably accommodated with the aid of a frame 9 is.
  • anode plates 10 which rise and fall on both sides of the the plastic film strip 1 are arranged and are connected via lines 11 to anode connections 12 of individual power sources not visible in the drawing.
  • a drive roller 13 is provided opposite the drive roller 5, via which the plastic film strip 1 emerging from the electrolysis bath 6 is fed to the drive and contacting rollers 14 and 15, which are located in a washing container 16. Two drive and contacting rollers are required if the plastic film strip is precoated on both sides and both sides are to be galvanically reinforced.
  • Arrows 17 indicate spray nozzles for water for cleaning the plastic film strip 1 from any electrolyte still adhering to it.
  • the plastic film strip 1 is fed via a further deflection roller 18 to a winding roller 22, which is likewise rotatably mounted in the wall-shaped housing part 3 and is provided with a drive motor which is not visible in the drawing.
  • Both the unwinding roller 2 and the winding roller 22 are provided with pushbuttons 23 which are connected via control shafts 24 to potentiometers for speed control of the brake and drive motors. These potentiometers are not shown in the drawing, since they are located behind the wall-shaped housing part 3.
  • the two drive rollers 4 and 5 are also designed as contacting rollers. Since the metallic pre-coating of the plastic film strip 1 is usually applied by chemical deposition or by spraying, this metal layer has an extremely small thickness, which with normal loop length has such a high resistance that the inlet circuit is only able to carry very little current is so that hardly more electrolysis takes place, so the separation is extremely low. Any increase in voltage or current would, however, burn the precoat. For this reason, for example in the known electrolysis plant, the precoated plastic strand is passed through the electrolysis bath in a plurality of sometimes shortened loops.
  • the two holders are provided with chambers 32 and 33, which are supplied with compressed air via channels 34 and 35, which then cools the strip in the chambers 32 and 33 and can escape in the direction of the arrow 36. This means that the current in the inlet circuit can also be increased.
  • the plastic film strip 1 emerging from the electrolysis bath 6 is also cooled, namely by spraying with washing water in the washing container 16 by means of the spray nozzles 17 and spraying with bath liquid by means of a spray nozzle indicated by an arrow 37 to close to it the vertex of the deflection roller 13.
  • spraying with washing water takes place through a further nozzle, which is symbolized by an arrow 38.
  • the spraying is not only used for cooling, but also to avoid the formation of stains on the electrodeposited coating due to adhering electrolytes.
  • plastic shields 40 and 41 are provided on both sides of the strip and on the side thereof, which shield the strip edges against the anode plates 10. They are arranged to be adjustable to the bandwidth and current density distribution transversely to the direction of movement of the belt.
  • the plastic screens 40 and 41 cover the edges of the plastic film strip 1 against the anode plates 10 over the entire length. These plastic panels 40 and 41 are for clarity shown only for the expiring loop portion, as well as the anode plates 10. They are of course also provided in the anode plates of the incoming loop part o
  • plastic screens 42 and 43 are preferably introduced into the bathroom from above to a depth of about 20 cm, namely between the strip and the anode plates. This achieves a better current density distribution on the anode plates 10 so that the current on the outlet side can be increased further without the layer being burned.
  • 3 shows the arrangement of the plastic covers with respect to the plastic film strip 1.
  • Such plastic covers can also be provided on the inlet side.
  • coating or reinforcement of the plastic film strip is only required on one side.
  • either only the sliding cathode 26 and the contacting roller 15 or only the sliding cathode 27 and the contacting roller 14 need to be energized, depending on which side of the plastic film strip is precoated.
  • FIG. 4 shows an exemplary embodiment of such an electrolysis plant.
  • a further unwinding roller 45 is provided for a second plastic film strip 1 ', which is transferred to the drive roller 5 via a deflection roller 46. From there it is then carried on together with the plastic film strip 1 to the deflecting roller 20 and finally wound up again on a winding roller 47.
  • the unwinding and winding rollers 45 and 47 are also provided with feelers 48 for detecting the diameter, so that the drive and brake motors, not shown in the drawing, can be regulated accordingly in terms of speed.
  • the deflection rollers 18 to 21 are located in a drying container 49 in which the plastic film strips are dried on all sides with the aid of fans. Arrows 50 indicate the direction of action for the sake of clarity of fans which are not shown.
  • the preferably electronic control of the electrolysis system is accommodated in a control cabinet 51.
  • anode bodies can be used which can be used without interrupting the electrolysis process.
  • a polyimide film of 25 / um strip thickness and 120 mm width was used .
  • the Cu layer could ver to 20 / um by the analysis system according to the invention be strengthened.
  • An acidic copper bath was used as the electrolysis bath with a maximum deposition rate of 0.6 / ⁇ m per min.
  • the inlet current was 3.5 A and the outlet current was 35 A.
  • plastic film strip was passed through the electrolysis bath 6 in only one loop, the length of the strip in the copper bath being 2 m.
  • the belt speed was 0.05 m / min.
  • plastic films are used to produce components integrated on plastic carriers, such as capacitors, crossovers, conductor tracks, resistors and plated-through holes.
  • the strip can be passed through the electrolysis bath again or several times, in which case the current strengths can be multiplied accordingly.
