From the manufacturer's perspective, we aim to be able to fully inspect all components within the beat rate of the line and generally do. I'm not aware of any competitive machines that do the random sampling that is suggested above, however it is do

Would like to hear the pro and cons of using a machine like CamAlot 3800 to apply past to PCB. What has been to your experiences?

I used a CamAlot 5000 to apply conductive epoxy on an aluminum substrate about 4 years ago. I used the largest diameter nozzle CamAlot had, and I bumped the dispense and dwell times way up. It was the slowest stage in the process, but it worked out o

We don't use the machine you suggest, but dispensing paste in front of a placer is a very powerful set-up for some production environments. Check the fine SMTnet Archives for a comparison between dispensing and printing paste.

Sorry for the abridged post� The remainder of the post was to ask if anyone is aware of any papers or proceedings that discuss problems associated with thick gold finishes and intermetalics. Thanks, Doug

First place to look is IPC-6012A w A#1 "Qualification & Performance For Rigid Printed Boards". I'll look at it later to see what's there.

Yes, 3.4 does not seem to apply. Consider that 3.5 might be more appropriate.
