So what are the basic contents of PCBA when testing ...

Before using PCBA, you need to test it beforehand. It can only be used if it passes the test. If it fails, it cannot be used. However, PCBA has many problems to consider when testing. First of all, you should know the main content of PCBA, then PCBA What are the basics when testing?


       1.ICT test mainly includes the on / off of the circuit, the voltage and current values and the fluctuation curve, amplitude, noise, etc.

 

2, FCT test needs to burn the IC program, simulate the function of the entire PCBA board, find the problems in the hardware and software, and equip with the necessary production fixtures and test stands.


3.The fatigue test is mainly to sample the PCBA board and perform high-frequency and long-term operation of the function, observe whether the failure occurs, and judge the probability of the test failure, so as to feedback the working performance of the PCBA board in the electronic product.


4.Testing in harsh environment is mainly to expose the PCBA board to the extreme values of temperature, humidity, drop, splashing water, vibration, and obtain random test results to infer the reliability of the entire PCBA board batch product.


5.The aging test is mainly to power on the PCBA board and electronic products for a long time, keep it working and observe whether there are any failures. Only after the aging test can electronic products be shipped from the factory in batches.


What are the PCBA test forms? I will introduce them here today. The PCBA process is complicated. During the production process, various problems may occur due to improper equipment or operation. The products produced cannot be guaranteed to be qualified, so it is necessary to Conduct PCB testing to ensure that no quality issues occur with each product.
