Does anybody know if a contraption exists that will minimize a PCB's tendency to become slightly bent after reflow? We have a new product that we're planning to assemble in a couple of months. The board is 9.7" by 13.4" and it is imperitive that we

We have few questions for BGA assembly. Specially with Fuji machines. 1. What are the testing mechanism other then X-rays. 2. How we get data from Fuji to check repeatability and reproducibility in terms of percentage and how it as calculated. 3. Do

Got handed an assignment for which I'm not totally qualified. Don't expect this forum to had me all the answers. Some answers are obvious as the device types are fairly self explanatory. As everyone knows, IBM had problems with their ceramic BGA dev
