i would say that you are there already. with 10,000 DPM0 you have a 1% fallout, you are at 99.9 basically. 1 out of a 1000 boards will fail? of course one thing we need to know is how many opportunitites do you count for a chip resistor for exam

If a PCB is already going through ICT and some additional inspection method is desired to increase first pass test yield rates, what are the advantages/disadvantages of AOI vs XRay? The most common problems seen are missing or skewed components and

Maybe someone else can help, like: http://www.ceeris.com/efficiency.htm. Check with the following SMTnetters: * Steve Gregory. He posted a thread within the past week or so on solderability testing. He used to work at a memory module manufacturer

Dont forget, if you dont want to print paste and deal with the challenges of placing components in wet paste, solid solder deposit can save you the cost of the stencil printer, while offering better first pass yields than traditional methods. It just

Dear Ms. Chunks, Your valuable input has been noted. Unfortunately, your approach won't work in this case. Our customers would like for us to have AOI. To be perfectly honest with you, if we could just rig up some camera-looking thing that move

We are currently using Mydata (12 and 15) and are now looking at Fuji CP-743 and IP-3, what quality expectation can I have? I am looking for First Pass Yield data from your production with CP-743 and IP-3 machines. Please state type of products you p

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

Reese, We would agree about the value of an ICT system, in a general manufacturing environment. However, a couple of notes apply: 1. ICT isn't a catch-all, either, and should be used to verify the process, not validate it. Quality should be buil
