HI, We are looking into expanding our current x-ray inspection from manually inspection one panel per lot to 100% automated inspection for all of our BGA and CSP builds. We have 100% manual inspection at the end of our SMT lines and we are consideri

Hi Mike- Just a few things to help me understand: What is the need to goto 100% inspection? Contract calls for it, had a high fall out, or high rel ?? Is the current inspection not meeting your needs? Cal

Doesn't that depend on your company's culture & management style? We (and I feel slightly dirty using this word)empowered our end of line inspection/touch up people & trained them to know what is good or bad - so issues can be immediately fed back,
Our Company handle AOI (Auto Optical Inspection) and SPI (Solder Paste Inspection) Machines.
