Can anyone give me some insight into what to look for on a used X-Ray machine. Or just any thoughts on using X-Ray inspection. We are getting more and more QFNs and our inspection seems a little subjective. Thanks.

Smaller and multi-row QFNs will probably require an oblique view/5-axis xray with resolution of at least 1 micrometer and preferably a nanofocus machine. Given the low standoff and small pad size, verifying wetting can be challenging on interior pad

The format is X,Y Theta of the component center for all placement machines. Gerber data can be useless, unless you have the reference from pin 1 to the component center. Some machines offer a CAD convertion tool. I don't know any machine, which can

Hello, I am writing a software that deals with chip placement on PCB and I would like to know if there is some standart way to describe what are the coordinates of the chips on the pcb, I know that Gerber file contains all the drill holes and tracks,
