Featured Content ■ Latest Trends in BGA Implementation Board Inspection Hybrid Inspection of Flying Probe Testers and JTAG Testing Andor System Support Co., Ltd. / Masazumi Taniguchi Takaya Co., Ltd. / Kohei Yanagida Overview BGA (Ball Grid Array) components have become widely used in various electronic devices, ranging from consumer products to industrial equipment, and more recently, automotive devices. However, a reliable method for inspecting boards with BGA components (hereafter referred to as BGA implementation boards) has not been established. This is because every inspection method has its advantages and disadvantages, and it is impossible to conduct a complete test using only one inspection method. Therefore, inspecting BGA implementation boards has become a challenge for many companies. In this article, we will introduce the latest technological trends in hybrid inspection that combines flying probe testers and JTAG (Joint Test Action Group) boundary scan as one solution to this issue. 1. Introduction 2. Inspection and Challenges of BGA Implementation Boards 3. Possibilities of Electrical Testing 4. In-Circuit Testing 5. JTAG Boundary Scan Testing 6. Hybrid Testing 7. Conclusion
