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 7"

Frank, A couple of suggestions: 1. You may consider investing in a SPC Software package which would allow you to do a detailed analysis of your process. Panasonic's CIM Software Product, PanaPRO, has a well defined SPC application that can be used fo

ICT testing to improve yields

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

Typical first pass yield in electronics

Electronics Forum | Tue Apr 27 07:20:34 EDT 1999 | Richard Marks

I'm a mechanical engineer and we buy electronic pressure sensors and switches. In doing quality audits, I need to understand what "best practice" will yield in terms of conforming product first time through the manufacturing process? Any data out t

On circuit board assemblies first pass yields need to be above 98%, if a supplier is below this level it is a indication that: he has poor control of the manufacturing process; Poor component selection (price over quality; excepted a poor design from

Low yields on RFM TR3000 transceiver ICs

Electronics Forum | Mon Jun 04 20:55:55 EDT 2001 | craigj

Have been having problems with the above IC but dont know why. Our profile is well within the manufacuters recommendations. We are getting a higher than desired first off fail rate and are concerned. It is not possible to inspect the soldering as the
