The industry standard for Resistivity of Solvent Extract (ROSE) Testing analysis is IPC-TM-650 Method 2.3.25 – Detection and Measurement of Ionizable Surface Contaminants by Resistivity of Solvent Extract (ROSE).

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

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

I have problemabout fault reject rate at AOI very high, due to inspection letter or marking on IC body. It have uncleary. When I check at raw mat'l of IC it no problem but after pass reflow process it show marking not clear ( Laser marking type). Ple

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"

What is changing the marking on the part? * Is flux residue coating the part to change the the way light reflects from the part surface? [Run a board with tape on the part, then remove the tape prior to AOI] * Is the heat of the oven changing the mar
