Don't have any specific links to papers and articles. Try searching on the IPC.org (plus APEX show http://www.goapex.org) and SMTA.org web sites. Any papers and articles on the process from equipment mfg.'s should be taken with a grain of salt. Sold

AccuFlex is the replacement for UltraPrint 1500. UP1500 is going obsolete. AccuFlex was desgigned for fast setup and changeovers and takes some tasks away from the operator. The UltraPrint 2000 was designed for high production, even though many users

Um...for you mylar guys....esd safe? Why worry about the first two prints. Worry if they power up or not when sent to funcitonal test. Zapp! I think I know where this is comming from. It is not that uncommon to have a sacrificial print. However,

What is the general consensus on automated solder paste inspection? In a previous life, when we implemented AOI equipment, we implemented it at the end of the SMT line; our reasoning was that our screen printers had adequate repeatability for our pr

| How are you inspecting pcbs post-reflow, are you inspecting all or sampling. The type of assembly involved would be mainly chip components with a mix of actives and a few 25mil and under pitch. | If you sample what are your fault rates looking lik

Also note , KY is SPI company and there 3D technology is just SPI tweaked to do 3D AOI, same can be said of Mirtec but bit better than KY. Generally they are slow in capture and this is why in EU and say high volume sites 3D has not penetrated much.
