SrTech, Thanks for popping in. Your MyData advice has always been good. Anyway, all of our TM8FC's do have the correct seperators. So nix that. I thought the timing only had to do with advancing and stopping the component into the pick line correctl

The recommended feeder for 0402s and especially 0201s is the green feeder with a 3.7mm spec. We use greens for 0402/0201, white for 0603, yellow for 0805s, and reds for tantalums. They work well, but sometimes you seem to get difficult tape. I hav

Chunks, I used to work in power electronics, and we had this design engineer who used to "blow moisture" on the high-impedance circuit and test for cleanliness. We were water washing in a OA-Water Soluble environment. He was convinced that there w

Hi Bert, It can be either - sometimes they put too much glue on the cover tape when it's sealed, and sometimes the feeder is not stong enough. We would get a lot of these on our fuji's after a shutdown, and they would diminish throughout the first

PSA - Pressure Sensitive Adhesive? I don't know which type of tape the affected reels of parts use but it is not sticky. Thanks everyone for the comments and suggestions. There were no missing teeth on the plastic take-up reels. I have cleaned an

Your concern should be do you have a glue process that can keep up with the FCP6. We ran a GL541 in line with a CP643 which the glue machine was actually a bottle neck because if you run SOIC's which require more glue dots then it will slowdown the

Yes there is RoHS certified ink it just cost twice as much as the regular ink. Just kidding Some people ask for RoHaaS compliance on cardboard boxes, pencils etc. What a mess $%^$ To answer your question, Ink is made from ethanol (ethyl alcohol) and

Hi Grant, just my opinion, I think the concern could be related to the extra temperature the BGAs have been exposed during the Lead Free Reflow Temperature. So you need to check ( data sheet) what is the max temperature and how long the Pb/BGA can w

Hi, Reliability was what I was worried about. We have not shipped these yet, as we are not sure about reliability. We can ship them in regions outside of the EU anytime so we are ok on that, and because of supply chain delays, we are already shippi

There are plenty of studies on this subject. If the BGA can handle the extra temperature and they are soldered on a leadfree profile, the general result seems to be a better reliability than Pb :) Just out of the top of my head, there was a link to
