The primary purpose of IC testing is to ensure that the device verifies that the IC can perform the intended work or function under harsh environmental conditions. Distinguish qualified chips and unqualified chips, to ensure product quality and reliability, the following take you to understand the IC test seat.

The IC test seat is used to verify that the IC can perform the work or function as designed. Functional testing is the foundation of digital circuit testing. It simulates the actual working state of IC, inputting a series of test modes successively or randomly, acting on the device under test at the rate specified by the circuit, and then detecting whether the output signal is consistent with the output of the circuit. The expected graph data match to determine whether the circuit function is normal. Its focus is on pattern generation rate, edge timing control, input/output control and mask selection.

The special head-shaped protuberances of the test seat probe can Pierce the oxide layer of the tin ball, reliable contact without damaging the tin ball. High precision positioning slot or pilot hole, to ensure accurate IC positioning, high production efficiency, replaceable probe, easy maintenance, low cost.

IC test seat adopts manual turnover structure and automatic compression structure, easy to operate; The clamshell cover IC press plate adopts the spring pressure structure, which can automatically adjust the downward pressure to ensure the uniform pressure of IC.

Analyze the precautions for using test fixture

Test fixture is a kind of auxiliary equipment that needs processing and manufacturing in order to realize the detection and testing of a certain product or semi-finished product and judge whether its function conforms to the original intention of the designer. It is mainly used to detect the quality of PCB circuit boards in the production line of electronic, electrical and computer OEM factories. So what points should be mastered when using test fixtures? Analyze the precautions for using test fixture

1. When the test fixture is damaged and cannot be repaired, the customer can replace it and do it again.

2. The test fixture shall be registered and used by the person in charge of the electrical test room. After use, it will be returned to the jig room and handed over.

3. After production, put it into the production room, put it on the iron frame of the fixture, and mark the model.

4. When the aging phenomenon of broken needle appears in the test fixture, the needle can be replaced for maintenance and continued use.

Electromagnetic interference /EMI is a problem that the whole electronic field needs to face and overcome at present, which is generally found in wireless communication products such as: Mobile phone, wireless network card, wireless router, wireless headset, Bluetooth headset, wi-fi, wimax, data card, walkie-talkie, RFID in the wireless communication equipment and wireless communication module board testing and testing process, The use of medium base combined shieldBox /TOJOINRFShieldBox as test fixture for RF testing improves the testing environment.
