Steve: I agree. Let�s break it down. * I�d rather print paste than glue any day of the week * But I know yera �Dispenser Boy�. In that case, I�d rather dispense glue than paste. * PTH / primary and SMT / secondary is a tough process either way you

| If you could measure and chart 3 variables in my process, what would they be? | The boards that I produce are on panels that are 12up and 2x4 up. All boards are single sided paper base w/o plated thru holes. They are on scored panels that measure

Julie: What is the benefit of your SQE requiring that your CE meet your first pass yield targets?

The DPMO is a far better measure - first pass yield doesn't give you any indication on quality or effectiveness of test step. If you want 100% first pass yield, test nothing - works every time - you see where I am coming from..........

I would trust that you are benchmarking some design rules as well? Yield is directly related to design as well as process capability. anyway 95% is not a bad first pass yield at all, and I would tend to think that that is a little high when dealing

I work for a memory module manufacturer and I am interested in obtaining information on typical first-pass yield numbers and failure rates in the memory module industry for benchmarking purposes. Any information provided would be greatly appreciated

With totally stable screen print (solder paste), placement and reflow processes, what is a world class target first time yield for good pcbs? How bad is 65% FTY. Your views would be welcome.

Our SQE's want to benchmark the first pass yield requirements that we place on our CM's - currently they are at 95% - does this seem reasonable?

I define First Pass yield without any repairs. But I only consider a PCB to need repair if it fails test. Our boards are inspected before testing and any work done before testing, I consider to be rework and is part of the SMT process.

Has anyone out there successfully switched from First Pass Yield to DPMO metrics and most importantly, sold MGMT on the change?
