We have this panel that is Gold Flash. Am I correct in assuming this is technically a lead-free panel then? We are running a WS paste, and the QFN28 has balls of solder instead of a fillet. My Max temp is 216, and the TAL was between 52-57 secs with

Not arguing dan, but are you positive that they are not copper? anyway, what is happening is as the parts sucks down onto the board from reflow the extra paste is notnecessarily sqeezed out but it has no place to go. So it will form this ball on th

Sorry about that(My bad), they are copper. I believe the same thing, we need to reduce the appatures as we are already at 5mil. Our main problem is the customer...Their tests were failing and for some reason they touched that part up, and then the un

The cover tape that seals the parts into the reels on our feeders always uncovers a few parts (up to ten 0805 parts) before the part can be picked. So removing a partial reel always results in the loss of a few parts. Putting a partial reel back on

this is all good jay but would WML have to say about this paste? I'm gonna wait for his response before I do anything! I am bringing in some samples of this soon to try for myself. I have a part that the manufacturer says to run with a paste with n

I'm just dying to hear. I think this past will be a contender for us, I'd use it but I allready commited to using the Kester EM907. Maybe after the first of the year I'll look at switching to this paste. Ive never heard of a problem like that, but
