Identification of defects can be performed in a short time! Introducing case studies of JTAG testing.

We would like to introduce a case where we implemented JTAG testing from CORELIS, a reliable and leading manufacturer in the industry (headquartered in California, USA). A major medical electronics manufacturer introduced JTAG testing in their production technology department in 2008 for the failure analysis of boards with BGA mounting and narrow pitch connectors. As a result, it became possible to ensure sufficient quality even for high-density printed circuit boards. 【Case Study】 ■Challenges - Failure analysis of boards with BGA mounting and narrow pitch connectors ■Results - Identification of failure points on BGA-mounted boards and boards with narrow pitch connectors at the pin level - Identification of implementation failures of pull-up/pull-down resistors, further improving manufacturing quality - Improvement of quality through the automation of X-ray inspection testing *For more details, please refer to the catalog or feel free to contact us.
