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

Not sure if you need help with the calculations or the application, so from the beginning: d=defective parts, p=number of parts, dpm=defects per million parts In a nutshell, d/p=dpm/1000000, so dpm=d/p*1000000 We use dpmo (defects per million op
