There are plenty of studies on this subject. If the BGA can handle the extra temperature and they are soldered on a leadfree profile, the general result seems to be a better reliability than Pb :) Just out of the top of my head, there was a link to

I'm only peripherally aware of CircuitCam; we were adopting it in a past-life, and I wasn't terribly connected with the adoption. However, I thought that it did have the capability of optimizing a job to a production line (assuming the two machines

Solder preforms can be used in SMT assembly for through-hole pin-in-paste process. In this process and modified aperture is used to print the paste with standard stencil printing, then a solder preform is picked and placed by a machine into the solde

Well, what I have takes data directly from the Protel 99SE placement file, so in the present form it is a bit specific. This file is simple ASCII text, but the layout of columns will be different on other CAD systems. What I have has a number of sh

I think Panasert MSR is a good machine. You can easily program these machines using text files. Panasonic pubishes the format. The CM88 is harder to program. You will need to use the PT200 machine controller program. Different text formats can be imp

Craig, I know just what you are looking for as we run product that is very similar to what you are talking about. Currently we have a in-house made soldering robot the we are using to solder
