Abstract

The invention provides an ICT jig that can automatically plug and unplug a CPU, including an upper needle board, an upper board and a download board for placing a board to be tested, a CPU slot is provided on the board to be tested, and a CPU slot is provided with a Tighten the screws. The board to be tested has a positioning hole adjacent to the CPU slot. A CPU opposite to the CPU slot is fixed on the bottom of the upper needle board. There is a through hole on the upper board. The through hole allows the CPU to be inserted The grooves are in contact with each other, and a screwdriver and a plurality of elastic guide posts are pierced on the upper needle plate. The lower ends of the screwdriver and the elastic guide posts penetrate below the upper carrier plate, and the screwdriver is connected with a driving device. When the upper needle plate descends, the elastic The lower end of the guide post is matched with the positioning hole, the CPU is inserted into the CPU slot, and the lower end of the screwdriver is in contact with the locking screw. In the process of using the ICT jig that can automatically plug and unplug the CPU to test the motherboard, the automatic plug and unplug of the CPU is realized, thereby effectively shortening the test cycle of the product and improving the test accuracy and test efficiency.

Description

technical field [0001] The invention relates to a test fixture, in particular to an ICT fixture capable of automatically plugging and unplugging a CPU. Background technique [0002] ICT (InCircuiTest) fixture is an online detection and test fixture, which is mainly used to check the open and short circuit conditions of individual components on-line and each circuit network. It can quantitatively test the resistance, capacitance, inductor, crystal oscillator and other devices. Carry out measurements, perform functional tests on diodes, triodes, optocouplers, transformers, relays, operational amplifiers, power modules, etc., and perform functional tests on small and medium-sized integrated circuits. [0003] The ICT fixture finds defects in the manufacturing process and defective components by directly testing the electrical properties of the online components. For components, it is possible to check out the out-of-tolerance, failure or damage of component values, and memory ...
