Does anyone out there have a lead to any specific research or studies on
the effectiveness of manual inspection of PCBA's? A crude rule-of-thumb
that we've often used is 80% (80% of actual defects are found by a single
inspection). I know there's a ton of variables (PCBA complexity, component
technology, magnification, fatigue, etc...) but I would think someone would
have documented a thorough study sometime. We've got a customer that's
demanding justification for our rule-of-thumb.
Also, can someone recommend a good ergonomics reference regarding manual
inspection? Thanks in advance.
