Electronics Forum | Tue Jan 16 18:13:25 EST 2007 | greg york

Try to process the composite pallet through the wave without any flux and view volume of smoke and if any residue is deposited in the wave when it exits. My guess is that the pallets are releasing some binders that are high boiling and this in turn c

Don't blame it on the poor paste thickness requirement [although I might go on to argue that it's could be a contributor to the issue]. Most likely you're the problem. About 70% of the time solder on gold fingers is caused by poor cleaning of screen

You are on the right track Ismir. Essentially however, as the programmer of the machine, I am the one that creates the PCB with the errors to benchmark the settings for the machine. No secret lab though! :-) Easy enough for most any AOI machine to
