Mike, when you ask if companies afford to place additional environmental constraints on the manufacturing process, perhaps we should ask whether they can afford not to pay attention to environmental issues. I know this sounds a little flippant, but i

Just my opinion: Top pic - Solder mask registration WAY too far off, without a doubt I would reject. Bottom pic - I would worry that there was/is a contamination that caused the poor looking mask. This may be cosmetic only, but unknown. I would rej

Base on the top picture condition, seems like the boards condition is a lot with solder splash or solder ball which is per IPC-610 is under reject (under 5.6.2)for class 3 product. While the picture 2 is showing those the solder resist is not melt pr

Umar - the boards are not assembled - so Solder splash is not applicable. Solder resist does not Melt it cures. As a board supplier I would not want my clients to adapt if they are receiving crap product, I would expect them to leave.

AOI if needed? I take it your AOI/AXI is not inline. Too bad. Our AOI is the first line of defense against induced errors in the mfg process. It's invaluable. How do you know it's not needed, or that it won't be needed in the future? Do you hav

Hello everyone, we are contract manufacturer and I am wondering if we can save some time from inspection and verification. We will usually inspect the bare boards, then, verify program to BOM, then feeders to BOM and Feeders to program,then paste ins

Hi Julie, My opinion is that the top board would not pass IPC, solder mask encroachment on pads. Second board is what we call Orange peel,this can be caused two way's. 1) the solder mask was not tack dried enough prior to imaging which caused artwo

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
