Description

Common matching board for test sorting machine

The invention relates to a matching board of a test sorting machine, in particular to a common matching board of a test sorting machine.

The semiconductor packaging factory sets up a test sorting machine to test the production of semiconductor components after the semiconductor components are completed to ensure that they function properly before they can be shipped. The test area of the test sorting machine is provided with a plurality of test circuit boards, each circuit board has a plurality of test sockets, and a plurality of semiconductor components are contacted with the test sockets at a time to complete the electrical test. The test sorting machine There are multiple matching boards, and each matching board will be replaced according to the circuit board provided by the customer for testing to correspond to the test socket on the circuit board; as shown in Figure 8 and Figure 10, the matching board of the test sorting machine The 80 series contains four pushers 85, which are used to press the corresponding semiconductor components on the test socket of the circuit board for testing. However, when the customer replaces the circuit board of a different number and position of the test socket, a different type must be replaced A matching board, such as a matching board with two pushing members 85, can smoothly press the semiconductor element to contact the corresponding test socket to complete the test.

As shown in Figure 7, the matching plate 80 is composed of four fixing members 81, four guide blocks 82, a setting plate 83, a base 84 and 2*2 pushing members 85, wherein the setting plate 83 is set On the top surface of the base 84, the base 84 includes 2*2 openings 841, each guide block 82 forms a first through hole 821, and each pusher 85 forms a second through hole 851; when assembled, As shown in FIG. 9, the guide blocks 82 are respectively slidably disposed in the corresponding openings 841 from above the base 84, and the second through holes 851 of the pushing members 85 are aligned with the corresponding guide blocks 82 After the first through holes 821 of the respective guide blocks 82, the fixing members 81 are inserted through the corresponding first through holes 821 from the top surfaces of the guide blocks 82, and fixed to the second through holes 821 of the corresponding pushing member 85. Therefore, when the matching plate needs to be replaced with a different type of matching plate, for example, a matching plate with two pushers 85, only the entire set of matching plates 80 can be removed, and then a different type of matching plate can be installed. Test cost; Furthermore, since the pushing parts 85 are fixed in the guide block 82 through the fixing parts 81, the fixing parts 81 need to be loosened before the corresponding pushing parts 85 can be replaced, which is very time-consuming; Therefore, further improvements are necessary.
