AOI should not a be a filter at which you throw a mix of good and bad parts to hope it filters out all the bad parts. It shouldn't be seen as a "fix" to the problem of shipping bad parts to your customer. It should be a tool to help you identify wh

Because we build Class 3 assemblies, our company has formal inspection steps on our routes. CCA's go through surface mount and then an operator inspects the solder joints for defects and corrects them (touch-up). Following this they go to formal insp

ASQC re-numbered the once free (taxpayer sponsored development) MIL-STD-105 as ASQ-Z1.4, slapped their own cover on it, and now charge $40 or $50 for the same document! The standards are identical, so see if you can get one of the old �MIL-STD's� and

Thanks for the responses. Actually we already use a reel change log with two verifications, a first off checklist with two verificaitons, and a first off inspection with two verifications. Unfortunately, the part numbers were pretty close, and the

Sal: JAX makes good points, but I�d like to think about this differently. It sounds like the poorly soldered connection is lifting the whole connector, so that termination floats on top of the solder, rather than submit to the wetting force and be

Have you had bad experiences? We have a paste checker on line, and all components are verified at receiving and again when loaded on the machines. The purpose of AOI ( for us anyway ) is to reduce the time spent after reflow visually checking the b

Jose, I have seen this defect before. We called it re-reflow. We found the part was originally attached at SMT. Later on after seeing a heat cycle at the wave machine the leads would de-attach causing an open at In-Circuit Test. Resolution was t
