Is anybody using IPC TR-640A? This is a troubleshooting checklist for wave soldering. Is it worth looking at?

Is there a guideline for the manufacturing of PC Boards? I find that my board changes dramatically from board house to board house, causing about 2% failure rate.

Hussman Comments are: * Generally, the "3b PCB Fab:" documents are written by the fabs. Nufsed * There's no reason that you cannot define your boards by specifying the stack [that you learn from the most preferred of the seven shops of your supplier]

Hi Hussman, I have no affiliation to this company, they are actually a competitor of ours,but they have a very good DFM Book on their Web Site that would probably answer some of your questions. www.sanmina.com/Solutions/pcb_resource.html Hope this

In addition to what DaveF said, I'd like to know if there are other parts on this pcb, and if the paste for those parts was printed accurately or not.

What is your alignment method for printing? Vision? Mechanical? What is the advertised repeatability for your machine? Russ

Those others parts also happend printed not accurate, but there is no solder problem. Only the QFP area looks bad condition.
