The company I represent provides electronic manufacturing services. Some of my customers ask that we ship their boards "un-tested". By un-tested I mean we build them, visually inspect them and out they go. I find that on un-tested boards, it's not

In my experience, the most commonly accepted theory is that 100% inspection is only 80% effective AT BEST. That means that if your inspoectors are happy, noy outside concerns, well-rested, etc, they will catch 80% of the defects. This number goes d

Tim, What Brian writes is all true. However, let em put it into a sales / marketing perspective..... The REAL issue in your situation is: Who is responsible for the failures which WILL result in shipping untested product? Typically, your customer

reject percentage of assembled circuits after initial test?

This is a question for those of you who actually assemble components onto a board. Any idea what the "industry standard" is for fall out on assembled PCB's? I realize that the controls put in place in your processes will effect your overall quality

Flux residue cause high false reject at ICT

For the better part of my career, I've battled with ICT guys on so-called "flux residues" on their test probes, and this was when using NO-CLEAN, 2% to 5% solids tops, flux. People don't understand that ICT probe maintenance is an inherent part of
