[Case Study] Achieving Quality Assurance for BGA Assembly by Adopting JTAG Testing
Feedback the statistical data of BGA defects to manufacturing!
We would like to introduce a case study of a customer who identified defective areas on a BGA implementation board using "JTAG boundary scan testing." By utilizing this product, it became possible to pinpoint the locations of BGA implementation defects at the pin level. A cross-sectional analysis conducted with a microscope on the pins where defects occurred revealed that the cause of the implementation defects was due to the soldering areas being exposed to high temperatures for an extended period. Additionally, by reviewing the temperature management of the solder reflow process, we were able to improve the implementation quality of the board.

Company information
Andor System Support Co., Ltd. is the first company in Japan to commercialize the business of system support, which assists users in system development using cutting-edge computer application technologies. It has been 45 years since its establishment. Looking back to the early days, it was about three years before the advent of microcomputers, which brought about the information revolution. Since then, as a pioneer of system houses in Japan, we have consistently utilized advanced technologies to develop numerous state-of-the-art systems in collaboration with our users, ranging from small mechatronics engineering training materials to large control systems for production lines and logistics transport equipment. We have embedded the concept of system support, which is reflected in our company name, as the foundation of our corporate philosophy, and we consistently carry out user support, not only through development but also through model production for mass production, consulting, market research, personnel training, and maintenance. In response to the new stage of globalization, we are committed to returning to the origins of our company and deepening the trusted system support for our users, while pioneering uncharted territories. Please look forward to Andor as a "trusted support group."
