Have you learned about PCBA test fixtures?
The PCBA test fixture is a very important equipment in PCBA processing plants. It is generally placed at the end of the production process to test whether the product is intact. When making and testing PCBA test fixtures, it is necessary to meet the specified requirements to improve the accuracy of the test and improve the quality of shipments.


1. What is the PCBA test fixture?
PCBA test fixture is a fixture for testing and testing product functions, power calibration, life, performance, etc. Because it is mainly used for the testing of various indicators of the product on the PCBA production line, it is called the PCBA test fixture.

2. Requirements of PCBA test fixture
1. According to the test requirements and the test board, after selecting the control method, the structure of the fixture can be designed, and the carrier board, pressure plate, connector module, etc. can be designed. There are corresponding protective measures to avoid damaging the test board during testing.

2. The positioning of the fixture is accurate, and the connection of the connector should be smooth.

3. The layout in the fixture box is reasonable, and the space for wiring and installing the control system is sufficient.

4. The optical fiber/MIC/SPK/SIM card analog card slot should be reserved and the location should be accurate.

5. The position of the reserved interface of the fixture should be correct, sufficient, and the layout should be reasonable.

6. The box body of the fixture should be locked by bag buckle or press buckle to facilitate replacement of parts and maintenance.

7. Correct zero point calibration. The zero point drift of the test fixture will change with the change of test conditions or the difference of the test fixture, so the zero point correction of open circuit and short circuit is very necessary. Therefore, the FCT test fixture has settings for open circuit and short circuit correction.

8. When the jig is broken or aging, the needle can be changed and used for maintenance. If the fixture is damaged and cannot be repaired for use and the customer changes and no longer uses it, it needs to be remade.


PCBA test fixtures are generally customized fixtures for a certain product, which can effectively improve productivity and shipping quality. At present, the country has higher and higher requirements for environmental protection and greater efforts in link governance. This is a challenge but also an opportunity for PCB factories. If PCB factories are determined to solve the problem of environmental pollution, then FPC flexible circuit board products can be at the forefront of the market, and PCB factories can get opportunities for further development.

The Internet era has broken the traditional marketing model, and a large number of resources have been gathered together to the greatest extent through the Internet, which has also accelerated the development speed of FPC flexible circuit boards, and then as the development speed accelerates, environmental problems will continue to appear in PCB factories. In front of you. However, with the development of the Internet, environmental protection and environmental informatization have also been developed by leaps and bounds. Environmental information data centers and green electronic procurement are gradually being applied to the actual production and operation fields.
