I am to implement PBGA, and i am looking for PCB surface finish informations. A lot of technical reports are specifing NiAu finishing because of flatness property. Because of leads shape, I though that BGA doesn't need flat pads like QFP. Is it false

You would be better served to check your print quality as you run. Any problems caused by dirty stencils ( plugged aps etc ) would show up right away as a defect. Search the forum for more on this subject. I seem to recall the same subject coming up

Dave, We have very short runs (less than one hour). We have stencils all over the place waiting to be cleaned. It is too time consuming to scope each stencil to inspect for cleanliness. Do you know of any automated or scanning devices that can ra

We are investigating a system, using 2-D matrix code, that will identify and track every PCB throughout our factory, starting from bare board. As a low-medium volume manufacturer, would labels or laser marking be more cost-effective? How difficult is
