[Case Study] Analysis of defective circuit boards returned from downstream processes and the market.
Easily identify the faulty areas on the circuit board for anyone!
We would like to introduce a case where Takaya's flying probe tester was implemented for failure board analysis in the quality assurance department. *Challenges Approximately 150 to 200 boards per month are returned from domestic and international markets due to failures. Operators were repairing by searching for defective areas with handheld testers, but it was labor-intensive, so automation was desired. The main causes of defects include component lifting, pattern breaks, and component destruction. Due to the variety of product types and the high cost of creating inspection jigs, inspection using the flying probe tester was introduced. The causes of defects include component lifting, pattern breaks, and component destruction. 〇Results - Faulty components were identified quickly without labor or oversight. - Simple functional testing allows for simultaneous operation testing. - By utilizing the accumulation and analysis functions of inspection results, trends such as differences in failure modes based on the country of shipment for the same board can be fed back into design. For more details about the flying probe tester, please download the PDF catalog or feel free to contact us.
