Hi Yannick. This is an issue that we are just recently getting into but here is some ifo that I have gathered so far. I have seen/ used 2 different rework machines. The one we have bought is a 'PACE TF2000' which was at the lower cost end of the mar

Touch-up and inspection of visual defects

Hi Daan, What we did in the time was pareto analyses on all board designs to determine the critical areas (mainly design errors) and only inspect those specific problem areas. Every batch had a copy of the PC board with problem areas marked and only

Top camera inspection and side camera

Manjunath The top camera will be used for probably 90-95% of your inspection needs. However, without side cameras that 5-10% of uninspected parts can be a real pain to manually verify. What you need to figure out is what is your product to inspe

Are you doing actual measurements of the dummy parts placements? or are you just doing a visual go/no go check? If doing actual measurements, be sure to use mil inch units of measure rather than mm. Mil will give you more accurate readings. mm force

Touch-up and Inspection Process

Electronics Forum | Thu Mar 03 11:49:23 EST 2005 | Rob

Doesn't that depend on your company's culture & management style? We (and I feel slightly dirty using this word)empowered our end of line inspection/touch up people & trained them to know what is good or bad - so issues can be immediately fed back,
