We have purchased 2 and will be implementing them in our line shortly. We have one for component inspection and one for paste inspection. We are planning on starting with it "dummed down" and then adding more variables and tightening our criteria a

We doubt that entrapped process chemicals cause under-etch. Over-etch maybe, but not under-etch Under-etch is an indicator of improper process control/improper chemistry during etching. Under-etch can result in bridging between traces, resulting in

We have filed returned (approx. 5%) of the boards that exhibit inner layer short @ a particular connector locations. X-section revealed there exhibit Cu residue, but aside from that, we also suspect there could be organic contaminant, what test shou

Hi, I have 4 years as an AOI Process Engineer and we are working with 3 types of AOI - Marantz 22X, VI3000 and Omron (RNS & VT-WIN2). For solder joint inspection (solder meniscus quality, insufficient solder, wetting problems, shorts (bridges) Omron

Yes, sure. In fact in some applications ICT is coming back. Mainly due to the fact that more and more SMT discrete components have no markings, so AOI cannot tell you if you have the correct value on the PCB. Fixed pin or flying probe ICT is a valuab

I dug this in the past and I couldn't find much as well. It is a short history, as it is all based on a digital camera(first attempts start 80s and 90s). I want to say most of the applications of CMOS and CCD cameras we started seeing around the yea

I have just carried out an evaluation project including Mirtec, MVP, Landrex and Viscom. If you are interested in my findings you can contact me offline. In short though, we found that each had plus points to them. If you could join together the outs

If the parts are hand placed and hand trimmed, why do you need to inspect whether the lead is in the hole. The operator should be inserting the part correctly. We have MIRTEC machines and they do a pixel comparison to "known good images". With a m
