Main content of PCBA processing test
PCBA testing is the most critical quality control link in the entire PCBA processing process. It is necessary to strictly follow the PCBA test standards and test the test points of the circuit board in accordance with the customer's test plan (Test Plan).

PCBA testing also includes five main forms: ICT testing, FCT testing, aging testing, fatigue testing, and testing under harsh environments.

Among them, ICT (In Circuit Test) tests mainly include circuit on-off, voltage and current values, fluctuation curves, amplitude, noise, etc.;

The FCT (Functional Circuit Test) test requires IC program firing to simulate the function of the entire PCBA board, find the problems in the hardware and software, and be equipped with necessary production fixtures and test racks;

The burn-in 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 burn-in test, the electronic products can be sold in batches;

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, such as continuously clicking the mouse 100,000 times or turning on and off the LED light 10,000 times to test the probability of failure. Feedback the working performance of the PCBA board in the electronic product;

The test under severe conditions 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. 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. Over the years, we are proud to maintain a 99% on-time delivery rate. We work in three shifts to ensure that your PCB can appear on your desk as planned and as early as possible. You can choose DHL and other courier services to balance speed and budget. We only use services from reliable and reputable companies.
