Larry- I notice most of your posts either start out or end up like ......."I don't know anything about this, but there was a guy that worked here and he told me"...... WTF? You're not bringing anything to the table when you make judgements/opinion

Larry, Are you a glutton for punishment, a masochist, just so sure that your answers are right and or important, or are you just REALLYYY bored at work and decided to be a dumb ass on the forums.. Loading boards into a flow solder machine for 12 ye

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

Pardon my ignorance on this subject but I gotta ask... When the SMT guys load partial reels, I'm told that they have to waste a few components in the process. It seemed obvious to me that there should be a kind of tape that can be added to the end

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

How big are the parts? I've only seen a few parts that ever fell off. Double sided reflow is probably the most common these days The surface tension is powerful. I think the lower limit of temperature is what you would have to worry about with epox
