There is a PCBA test fixture in the PCBA technical equipment workshop of PCBA board manufacturer, which is a fixture for testing and testing the function, power calibration, service life and performance of products; It is usually placed at the end of the production process to detect whether the product is intact. When making and testing PCBA test fixture, it is necessary to meet the specified requirements in order to improve the test accuracy and delivery quality.
PCBA test fixture
PCBA test fixture is mainly used for testing various indexes of products on PCBA production line, so it is called PCBA test fixture. Generally, PCBA test fixtures in patch processing plants are classified as follows:
1. ICT test mainly includes on-off, voltage and current values, fluctuation curve, amplitude, noise, etc. of PCBA board circuit.
2. The FCT test needs to burn the IC program, simulate the function of the whole PCBA board, find the problems in the hardware and software, and be equipped with necessary relevant production fixtures and test racks.
3. The fatigue test is mainly to sample the PCBA board, operate the function at high frequency and for a long time, observe whether the PCBA sample plate fails, and judge the probability of failure in the test, so as to feed back the working performance of PCBA board in electronic products.
4. The test under harsh environment is mainly to expose the PCBA board to the temperature, humidity, drop, splash and vibration of the limit value, and obtain the test results of random PCBA samples, so as to infer whether the whole PCBA board can be mass-produced in the PCBA technology production workshop.
5. The aging test of PCBA patch processing plant is mainly to power on the PCBA board and electronic products for a long time, keep the board in normal working state, regularly and closely observe whether the test board has any failure, failure and other related problems. Only electronic products of normal and high quality can be sold in batches after aging test.
