PCB Technical - What are the PCBA test forms

What are the PCBA test forms
The process flow of PCBA patch processing is very complex, including multiple important processes such as PCB board manufacturing process, component procurement and inspection, SMT patch assembly, DIP plug-in, PCBA testing and so on. Among them,PCBA testing is the most critical quality control link in the entire PCBA processing process, which determines the final use performance of the product. So what are the PCBA test formats?

PCBA test mainly includes five forms: ICT test, FCT test, aging test, fatigue test, and test under harsh environment.

1. ICT test mainly includes circuit continuity, voltage and current value, fluctuation curve, amplitude, noise, etc.

2. FCT testing requires IC program firing, simulation testing of the entire PCBA board function, discovery of problems in the hardware and software, and the necessary production fixtures and test racks.

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

4. The test in harsh environments is mainly to expose the PCBA board to extreme temperature, humidity, drop, splashing, and vibration, and obtain the test results of random samples, thereby inferring the reliability of the entire PCBA board batch product.

5. The aging test is mainly to energize the PCBA board and electronic products for a long time, keep them working and observe whether there are any failures. After the aging test, the electronic products can be sold in batches.

What are the PCBA test methods, I will introduce them here today. The PCBA process is complicated. During the production and processing, various problems may occur due to improper equipment or operation, and there is no guarantee that the products produced are qualified. Therefore, PCB testing is required to ensure that each product does not have quality problems. . 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 him. 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.
