Description

  The present invention relates to a test socket, and more particularly to a structure that allows a semiconductor module having a different size corresponding to a model to be mounted in a test socket for testing a semiconductor module.

  In recent years, mobile phones equipped with solar cell modules have become widespread, and there is a demand for downsizing and lowering the price of solar cell modules so that they can be installed in small devices. Along with this, the efficiency of power generation has been increased, and half-sized solar cell modules have become widespread.

  In the manufacturing process of the solar cell module, various tests are conventionally performed in order to screen for defective products. Solar cell modules are usually tested by irradiating light equivalent to sunlight to conduct electrical tests and characterize the solar cell module in the test socket provided in the tester. And do it.

  Hereinafter, a conventional test socket will be described in detail.

  FIG. 7 is a perspective view for explaining a test socket of a conventional solar cell module. FIG. 7A shows a state in which a socket body (pedestal portion) and a socket lid member (lid portion) are separated from each other. 7 (b) shows a state in which a socket lid member is attached to the socket body.

  As shown in FIG. 7, the test socket 200 includes a pedestal portion 210 and a lid portion 250, and a solar cell module pocket portion 230 that accommodates the solar cell module S is attached to the pedestal portion 210. A frame member 220 is fixed to the pedestal portion 210, and a first recess 220a corresponding to the shape of the pocket portion 230 for attaching the solar cell module pocket portion 230 is formed by the frame member 220.

  Further, the solar cell module pocket portion 230 is formed with a second recess 230a corresponding to the shape of the solar cell module S.

  Further, the pedestal part 210 is provided with a contact part, and this contact part is arranged so as to be positioned on the bottom surface of the second concave part 230a formed in the solar cell module pocket part 230. There are a plurality of contact pins (not shown) for electrical connection.

  On the other hand, the opening 250a corresponding to the shape of the portion of the solar cell module that irradiates light is formed in the lid 250 at a position corresponding to the second recess 230a.

  For example, in the manufacturing process of a solar cell module, the solar cell module is set in a socket connected to a tester, the test apparatus and the solar cell module are connected, and selection of non-defective products and defective products is performed, and performance surveys are performed. .

  By the way, the module pocket part 230 is a model-compatible part, and when a solar cell module of a different model is tested, it is exchanged for one corresponding to the model to be tested.

  This is due to the following reason.

  In other words, with test sockets that support specific types of solar cell modules, when testing other types of solar cell modules with different shapes, it is necessary to prepare test sockets that are compatible with other types of solar cell modules. There is a need to make a test socket for each shape of the solar cell module. However, as described above, in the socket in which the module pocket portion 230 is replaced with a model-compatible one, there is one type of socket. What is necessary is just to prepare multiple types of module pocket parts as corresponding parts.

  Further, as a technique related to positioning of devices under test having different sizes in the test socket, there is one disclosed in Patent Document 1, for example.

  In this document, as a positioning means for positioning and fixing the device under test in a direction (first direction) parallel to the top surface of the device under test in the accommodated state, a predetermined diagonal line is used among the corners of the device under test There is disclosed a test socket having a movable chuck that urges the two corners of each of them toward the center from one direction.

Thereby, the pressing block 130 presses the solar cell module Sb mounted on the mounting surface toward the module contact portion. The pressing block 140 also presses the solar cell module Sb mounted on the mounting surface toward the module contact portion 110c. Thereby, the solar cell module Sb is positioned such that the test terminal Pa is positioned on the contact terminal 110d of the socket body 110.

And an air storage tank 161b for supplying compressed air to the cylinder body 163b and a valve mechanism 162b for supplying compressed air from the air storage tank 161b to the cylinder mechanism 163b when the socket lid member 150b is mounted on the socket body. Note that the second air pressure generation mechanism (not shown) has the same configuration as the first air pressure generation mechanism 160b. The air storage tank 161b is supplied with compressed air from a compressor (not shown) outside the test socket.

  The operation will be briefly described below.

  6A, with the socket lid member 150b removed, the solar cell module Sa is placed on the placement surface 110a of the socket body 110 (FIG. 6A), and then the socket lid member. 150b is attached to the socket body 110 (FIG. 6B).

  The valve mechanism 162b receives a pressing force from the socket lid member 150b when the socket lid member 150b is mounted on the socket body, and the compressed air is sent from the air storage tank 161b to the cylinder mechanism 163b by the pressing force. Open the flow path.

  Thereby, the cylinder mechanism 163b moves the movable rod 164b attached to the pressing block 130 via the spring member 165 so as to press the solar cell module Sa toward the module contact portion side.

  Similarly, the movable rod (not shown) attached to the pressing block 140 can also move the solar cell module Sa to the module contact part side by the second air pressure generation mechanism.

  Thereby, the solar cell module Sa is positioned such that the test terminal Pa is positioned on the contact terminal 110d of the socket body 110. At this time, the contact portion 150d of the socket lid member 150 presses the upper surface of the side portion extending in two directions from the vertex A of the solar cell module Sa, and the test terminal Pa and the contact terminal 110d of the socket body 110 The electrical connection is made.

  As a result, the solar cell module Sa is electrically connected to a test apparatus (not shown) via the test socket 100a, and the test can be performed.

  The solar cell module Sa is different from the solar cell module Sa when the solar cell module Sb having a different size and the small size is mounted on the test socket 100b, as in the case of mounting the large solar cell module Sa. Electrical connection with the test socket can be made.

  As described above, in the third embodiment, similarly to the first embodiment, it is possible to cover the test sockets of solar cell modules having different shapes and sizes with one socket, and the design, production time, and production cost of the socket. There is an effect that can be reduced.

  In the third embodiment, the urging means is configured to generate the urging force that presses the pressing block by air pressure, so that the pressing force when positioning the solar cell module can be easily adjusted. Thus, the positioning can be performed in consideration of the strength of the solar cell module.
