Description

 Electronic component crimping unit and test equipment for its application  

The invention provides an electronic component crimping unit capable of changing the crimping force and the displacement speed of the presser in response to the test operation requirements of various types of electronic components, and achieving the test quality, improving the use efficiency of the device and saving the equipment cost. Test equipment for its application.

In today's world, electronic components (such as ICs with solder balls) are divided into logic ICs, memory ICs, analog ICs, and micro-component ICs. The positions and quantities of solder balls of different types of electronic components are different. Any type of electronic component must be tested on the test equipment to eliminate defective products and ensure product quality.

Please refer to the first and second figures. The test equipment is mainly provided with a test device 10 and a crimping unit 11 on the machine base. The test device 10 is provided with a plurality of test sockets 102 on a test circuit board 101, and A plurality of probes 103 are disposed in each of the test sockets 102, and springs 104 are respectively disposed under the probes 103, so that the probes 103 can be elastically stretched and displaced; the crimping unit 11 can drive displacement to the test. Above the device 10, the crimping unit 11 is provided with a presser 111 driven by a driving mechanism to be displaced in a first direction (such as a Z direction). The bottom of the presser 111 is respectively provided at a position corresponding to each test socket 102. A plurality of electronic components 20 are disposed at the same time, and the driving mechanism is provided with a motor 112. The output shaft of the motor 112 is coupled to a lead screw 114 by a pulley set 113. The presser The screw 112 is screwed onto the lead screw 114, so that the motor 112 can drive the lead screw 114 to rotate via the pulley set 113, and then the lead screw 114 drives the presser 111 to raise and lower the displacement; 4, when the test operation is performed, when the crimping unit 11 will be plural After the electronic component 20 is transferred to the upper side of the test device 10, it drives the pulley set 113 with the motor 112, and drives the lead screw 114 to rotate via the pulley set 113, and drives the presser 111 to perform the first direction (such as the Z direction). Pressure displacement, and each electronic component 20 is placed in the corresponding test socket 102, so that each solder ball 201 of each electronic component 20 contacts each probe 103 in each test socket 102, and in order to make the electronic component 20 Each of the solder balls 201 surely contacts the probes 103 in the test socket 102 to ensure test quality, and the electronic components 20 are continuously pressed down by an appropriate distance to ensure the solder balls 201 and test sleeves of the electronic components 20. When the probes 103 in the block 102 are in contact, the test operations of the plurality of electronic components 20 can be performed simultaneously. When the presser 111 presses down the electronic components 20, in order to allow the probes 103 to be received by the electronic components 20 The solder ball 201 is pressed against the compression spring 104, and the motor 112 of the drive mechanism must be able to output sufficient torque so that the downforce of the presser 111 is sufficient to overcome the reaction force generated by all the springs 104 to ensure the tin of the electronic component 20. Ball 201 and test socket 102 The probes 103 are in contact with each other. Therefore, in order to selectively configure the motor 112, in addition to having to consider the rotational speed outputted by the motor 112, the presser 111 is quickly moved up and down to improve the working efficiency, and the torque outputted by the motor 112 must be considered. The downward pressure of the presser 111 is sufficient to overcome the reaction force generated by all the springs 104, and the appropriate motor 112 is selected under the double consideration of the rotational speed and the torque; however, due to the various types of electronic components and different types of electronic components The position and quantity of the solder balls are not the same. When the test of other different types of electronic components is performed on the machine, if the number of solder balls of the electronic components performing the test operation is small, the machine can be replaced with other machines. Corresponding test device, because the number of probes and springs in the test sockets is reduced according to the number of solder balls of the type of electronic components, and vice versa, the reaction force generated by all the springs is reduced, and the motor 112 drives the presser 111. The resulting downforce is still sufficient to overcome the reaction forces generated by all the springs, and the test can be performed; however, when performing the test operation When the number of solder balls of the sub-component is large, another corresponding test device is replaced on the machine table, because the number of probes and springs in each test socket of the test device is the number of solder balls corresponding to the type of electronic components. Increasingly, in contrast, the reaction force generated by all the springs is increased, and the downforce generated by the motor 112 to drive the presser 111 may not overcome the reaction force generated by all the springs, making it difficult for the presser 111 to carry the electrons. The components continue to press down the probes to compress the springs, and it is impossible to ensure that the solder balls of the electronic components are in contact with the probes in the test socket, thereby affecting the test quality.

In order to solve the above drawbacks, a motor with a large output torque can be installed on the machine to meet the test operation requirements of various electronic components. However, the motor with higher output torque is higher in cost. Moreover, the larger the volume is not conducive to the configuration of the space, and the more the output torque is, the slower the output speed is. In contrast, the speed at which the motor drives the lifter to move up and down becomes slower, which affects the overall test work efficiency; Under the double consideration of the test operation requirements and test efficiency of various electronic components, it is necessary to purchase various test equipments with different output torque motors, and perform different test equipment according to the test operation requirements of various electronic components. Test operations, which not only reduce the performance of each test equipment, but also significantly increase equipment costs.
