Doug, The spreading of information is a plus in my book, I am a big fan of IPC docs for that. And I tip my hat towards anyone who pulls together a good process analysis. But more often "Consensus Documents" are used as a "Specifications" by hordes of poorly trained "Technical Experts". Some of the nonsense about paste expiration dates, final rinse in DI water and other are perfect examples. Without a doubt there is much each of us needs to learn, and there are many issues in a manufacturing process. But a "Consensus Document" leads too many to stop thinking and stop learning. The result is the bitter reward.

Bob, while there are down sides to consensus documents, they are pretty darn good when you consider the alternatives and provide a common ground that make "exceptions" easier to do. I know I would much rather say, use workmanship per IPC-A-610, except for A, B, C. Rather than write a complete document, which I have done. Taint easy.

What may be good as a general guideline may not be adequate for niche applications or for various industry segments. We have the same issue with the IPC-A-610. Excellent as a base document but does not necessarily have what our Aerospace company needs for some applications, so we make exceptions for those.

I have a very basic question here. Why do we require our own specific DFM guidlines (every OEM / CM will have their own specific DFM Guideline) when we have the IPC guidelines defined and available? I am looking for the pointers and specific examples which can highlight the need to have and develop specific DFM guidelines for a company. Thanks in advance.
