Diaphragm-holding device for test

Abstract

The present invention relates to a diaphragm -holding device for test. It includes a fixing seat that can changeably clamp electronic module, holding sheet whose form can be elastically changed, electric connection unit and pneumatic control unit that are substitutionally fixed on the holding sheet. Besides, said invention also provides the working principle, and concrete operation method and steps of said diaphragm- holding device.

Description

technical field [0001] The invention relates to a clamping device, in particular to a clamping device for holding an electronic module for electrical testing. Background technique [0002] refer to figure 1 Generally, the electronic module 1 includes a circuit board 11 with a circuit, a plurality of integrated circuit packages 12 (integrated circuit packages) welded to the circuit board 11, and a plurality of integrated circuit packages arranged at intervals on one side of the circuit board 11. Each integrated circuit package 12 is electrically connected to the circuit of the circuit board 11, and each electrical contact 13 is also electrically connected to the circuit of the circuit board 11. The module 1 is electrically connected to another electronic product through a plurality of electrical contacts 13 , so that the electrical connection functions. For example, generally the most common electronic module 1 is a dynamic random access memory (RAM) that can be connected t...

Problems solved by technology

[0011] Although the above-mentioned diaphragm pinching device 2 can hold the electronic module 1 for electrical testing, since the clamping unit 22 is driven by the driving cylinder 24 to move, it will not only generate a lot of noise during the action, but also because of the instantaneous pinching The pressure makes the first electrical connection row 232 of the electrical connection film 231 easy to wear and must be replaced frequently

Furthermore, the circuit board 11 of the electronic module 1 will be bent and deformed due to the welding of multiple integrated circuit packages 12, or due to the influence of external temperature and absorption of water vapor, etc., thus causing the two clamping claws 221 to rigidly clamp the electronic module. 1 cannot be closely matched, so that the first electrical connection row 232 of the electrical connection film 231 cannot be electrically connected to the corresponding electrical contact 13 correctly, resulting in an increase in the false detection rate
