Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a performance board used in a device for automatically acquiring characteristic data of a pin electronics card used in a test head of a semiconductor IC test device in the field of electronic measurement technology.

[0002]

[Prior art]

 When measuring the characteristics of an IC device such as an IC memory using a semiconductor IC test apparatus, it is necessary to apply a measurement signal in a high frequency range to the IC device. It is applied to the test head of a test board (Performance Board) of the test apparatus by a pin card (Pin Electronics Card). (See FIG. 3) The pin card group is provided from the manufacturer of the test apparatus to the user. At that time, provide the data by confirming that the characteristic data such as the signal waveform applied to the IC device via the performance board conforms to the specifications over the entire measurement frequency range of the IC device. I have to.

Conventionally, a performance board provided to a user and actually used has been used to check with a sampling oscilloscope or the like in a situation similar to an actual use state. Moreover, by holding the prober of the oscilloscope by hand and making contact with the through-hole pattern of the performance board one by one, the characteristic data of the signal waveform has been obtained. However, with the increasing integration and functionality of IC devices, the functions required by test equipment have also increased dramatically, extending to the high-frequency range (1.3 ns to 500 ps), the number of channels has increased to 1000 channels, and the characteristic data to be acquired has to be acquired. Has reached 20 items, and the conventional method requires too much time for measurement and is inefficient. Since the measurement is performed in a high frequency range, the output characteristics of the pin card (eg, waveform) However, there was a problem that the measurement accuracy of the measurement could not be obtained.

[0004]

[Problem to be solved by the present invention] In order to solve the above problems, the present invention improves the accuracy of measuring the characteristics of the pin card, and furthermore, the number of channels and the number of measurement items become enormous. The purpose was to improve the efficiency of measurement work that required a long time.

[0005]

[Means for Solving the Problems]

 In order to achieve the above purpose, if there is only a through-hole pattern like a performance board provided to the user, it is difficult to obtain the contact repeatability of the measurement prober. Therefore, a larger pad (PAD) is required around the through-hole pattern. In order to increase efficiency by eliminating the need for manual operation and to eliminate the influence of the human body on the measurement system, a device that can be operated automatically and for a long time by unmanned operation using a prober that can move on the XY axis. did. In other words, apart from the performance board provided to the user, an array of patterns that can be easily automated is provided, and large pads are provided using contact materials (for example, gold plating) so that the prober can be repeatedly contacted with certainty. And a performance board dedicated to pin card characteristics measurement.

[0006]

[Action]

 (1) Most of the performance boards provided to users are custom-made according to the specifications of the users, and the configuration of the test head is not necessarily high precision and high efficiency as the purpose of the present invention. It was inconvenient to obtain pincard characteristics data. (2) The use of the performance board provided to the user eliminates the need to acquire pin card data for other purposes, so it is a commodity and does not damage the expensive pattern of the board. . (3) If the dedicated performance board for the automatic pin card data acquisition device is made of a dielectric material under the same conditions as the performance board provided to the user, errors in the measured values due to differences in impedance can be prevented.

[0007]

Embodiment (1) FIG. 1 shows an embodiment of the present invention. The performance board 1 for exclusive use of pin card characteristic data acquisition is provided with through holes 10 on the printed circuit board 4 and the pads 2 around the through hole patterns 3 at both ends, similarly to the custom performance board 9 provided to the user. . They are adjusted to the pitch of the pogo pin 6 of the pin card 7. (2) The pin card 7 becomes a group of pin cards (FIG. 2.2B) and is installed as a test head 8 below the performance board 1 (FIG. 2.2A), but the pad 2 of the dedicated performance board 1 is The arrangement and the size are set so that the automatic measurement prober 5 can operate efficiently for a long time and can surely make contact. (3) The dedicated performance board of the present invention is not limited to the square as shown in FIG. 1, but may be circular, triangular, or may have characteristics (eg, impedance matching) with the custom-designed performance board 10 provided to the user. For other reasons, other shapes and sizes can be used.

[0008]

[Effect of the invention]

 Since the present invention is configured as described above, it has the following effects. (1) The realization of a dedicated performance board that can acquire the characteristics of a pin card using an automatic acquisition device has made it possible to automatically operate for a long period of time without human intervention, greatly improving efficiency. (2) At the same time, repeated contact operation between the prober and the pad, which is the measurement point, is also ensured, and the measurement accuracy is improved even in the high-frequency range, so that the pin card shipping quality can be assured.
