GEB, Datasheets are usually just guidelines and most App. Engineers from paste companies will tell you that as well. You don't have to "copy exact" what they say, but rather set your oven to what gets you and your type of boards the best results. P

Hi All, I know some of this has been covered - but nothing recent that I could find - so please bear with me... Seems like the used/refurb market is kind of fluid so would like some current thoughts.... I'm looking to setup an inexpensive prototype

Guys! witnessing a problem i've never seen before.Manufacturing a mixed technology with HASL finish, BGA,QFP's,fuses etc..etc. I've profiled the product, but what i'm witnessing is really weird. I've got a 0.020" QFP which is at the edge of the board

Hi All -- I have read the IPC acceptability requirements of butt-joints, but haven't seen anything on how they're actually performed. I'm assuming we can trim a DIP package, and place the part onto paste immediately before relow (or hand-solder it l

Yes l know this problem keeps cropping up on the forum but l've missed some of the follow-ups. Our problem is that the lifting only occurs on 3% of production so actually detecting an improvement is difficult. We're actually having to inspect 144 p

Recently started running flex board with tin lead connectors. The problem being that when we receive the parts incoming connectors are all bright and shiny. Now after going thru the heller we encountered cold solder. At this time peak temp was at 186

You weren't specific about the frequency band were you're operating. So, let's pound a couple of stakes in the ground. * Conventional tin-lead plating of 200-300 �m is quite satisfactory for lower frequencies in the range of 2GHz. * At frequencies h

The first thing I do when looking at a part relative to stencil design, is determine the coplanarity per the data sheet. Ideally your stencil thickness should be equal to, or if needed, greater than the coplanarity. You want the solder paste to com
