IPC7912 deals with the end result, ie an OEM getting boards from a contract manufacturer. I have a friend who is sitting on these committees. He tells me there is a new standard due out for actually doing in-process DPMO. From a process standpoint

I believe that this is discussed in such documents as MIL STD 105, or other statistical sampling plan specifications. Russ

If you're the type to inquire (and truly care) about FPY then mechanical centering is NOT for you.

Looking for broad industry data for goals for FPY. What is a good bogey? What is minimally acceptable?

How do you know they are not missing before they go into the wave solder? It could be a handling issue.......

We have witnessed capacitors falling off in wave due to mold release being present on the component.

Almost zero? What's your definition of that? DPMO of 0? FPY?

We have CM's that manufacture products and have established global FPY goals (across all products). My question is, how can I determine if the established goals are appropriate to meet my final quality expecations (at the customer)? Are there indus

Typical of QE types. They don't know the entire process of qualifying what makes a "good" board (besides FPY), so they just arbitrarily come up with 95% FPY as a benchmark. Russ made a great point that alot of yield issues are design-related. Typi

IMHO, depending on whether its a regular run model, or a properly designed/setup pilot run model, getting a mean 75%-95% First Pass Yield (FPY%) is possible as a benchmark target. This is derived from your manufacturing history capabilities, and requ
