I have an Emerald X machine (by Assembleon) with an LCS. I start production. The first PCB board runs to the end of the LCS (item 1). Each subsequent stop is BEFORE LCS (item 2) - I have to remove it manually. And so until the production reset - then

This feedback is greatly appreciated! I had my reservations on the connection validation features, as you said good in theory but I really wanted some practical information without having to purchase to get an extended feel on our various application

We've never heard of seen of such a thing either. We tried a clean sample board and applied con coat. Same process through out and we saw nothing. After speaking with the original operators who was curing the boards he had left the boards much longer

Hi, I have an older Samsung pick and place (CP-40LV model). During last few runs I have experienced several feeders with the clear plastic tape cover not peeling back to expose the next part. I manually pull back the tape and it runs for a while and
