Thanks for your replys but I can't figure out why this problem is so much bigger in one owen when we run nearly the same mix in both our lines and we use in 99% of the production only the same 2 different pastes, lead and leadfree. The pastes we use

How did I know senior was going to get in here too. Nice to see you again. I figured as much with the height difference, but I do not have the equipment here to test my thoughts. We somehow have our machine dialed in to run the 0201 parts with W

Thanks all for the advice so far. I'm definitely considering the 4C & the TP9-U. I've also seen a Zeva 575, Philips Eclipse, & Juki 720. These seem to be a little more expensive. Any feedback on these machines - is the extra expense worth it? How e

I'm curious if anyone has figured out a clever way to errorproof this. We're exempt from RoHS so we have mostly SnPb products but some Pb free ones at customer request. Of course, we have methods to control moisture sensitive parts, but I worry tha
