Hi Paul,
That is what the buyers of the White Paper tell me [and Technet].

At $495, based on your contributions to
this forum & my past experiences I suspect it’s a bargain!!

Hi Paul & Rob,

It is for these reasons I developed a White Paper "Recommendations for PCB
FAB Notes and Specifications in Printed Circuit Board Drawings for SnPb and
Lead-Free Soldering Assemblies, the Qualification of PCB Shops and Activities
to Assure Continued Quality."

Rob,





I'm afraid I can't give you a answer to your specific issue (I doubt there





is a simple answer/reason), but I've been witness to similar issues





regarding board reliability in the past - the company I worked for spent a





lot of time & money=2
0trying to resolve the issues; some were down to board





design but in the main it was found that price was dictating the PCB shops





we used & they simply were not capable of producing defect free boards





consistently. In the end we put in place PCB design guidelines & a  series





of PCB specification tests for bare boards that approved the PCB shop & the





material set. Cost for each qual was in the region of $5K. I hope this





response will be of some assistance & apologies if this response is low on





specifics regarding your query.
