Visual inspection

It is highly recommended to use functional test fixtures to test every board that comes off the production line to minimize defects and avoid defective products reaching customers. Despite these efforts, final testing of assembled PCBs is crucial as it serves as the ultimate evaluation of both the product and the process. This final testing may involve both dynamic methods and automation systems, often used in combination. "Manual" testing relies on visual inspections by operators using optical instruments, while automation systems use computer-aided graphics analysis to detect defects. An automation system may include all methods except for manual light detection. Read More

This article introduces the basic standards of FPC testing and methods to improve testing efficiency. With electronic products becoming thinner, the demand for FPC has increased. FPC, mainly used for circuit connection in electronic products, features ultra-thin, high density, high reliability, and bending resistance. Testing from aspects of appearance, process, and performance is crucial for enhancing FPC product yield and preventing defects from entering the market. Using spring micro-needle modules can enhance testing efficiency. Mastering the basic standards of FPC testing contributes to testing stability and maximizing the performance of FPC. Read More
