I think that the IPC spec only apply to the MSD. I had a paper from Lucent and forwarded by Francois Monette, please aware that the first 2 hours, the moisture doesn't bake out from the assembly/component and result show that it is increase the weigh

I actually built a dual tank fluxer for my Econo-Pak once to handle the same thing. Not all that difficult if you're mechanically inclined. BUT, for your application I'd recommend just hand spraying the 1 to 4 boards a month with any flux they reco

yngwie, Hi mate, and Holy Crap! what a blooming pile of 7 feet dung you have sitting on your front lawn! ok, we had a customer SQE like that before, fortunately she was promoted from SQE to purchasing officer. and in the name of universal sharing,

Hi mates, just my 2cents worth... some folks (like us) have product runs that have BGA using no-clean, coupled that with Class3 IPC-A-610 specs, topped with aerospace/military customer defined specs. we end up cleaning NC with a degreaser machine w

Sam, I can tell you right now that if you have a low volume hi mix application where the program/job is changing every day, an AXI system is not going to be a good fit. As you alluded to, the programming time is onerous, the fine tuning or tweaking i

Tough. 0402 capacitors are more prone to tomb stoning than resistors. Tailor your process to the 0402 and let the other stuff fall where it falls. Search the fine SMTnet archives for discussion on tomb stoning. Consider: * Changing paste. * Apply

guys thanks for the suggestions... DaveF, *Changing paste EricD: Yes we are considering that as a point. Because I believe the paste we are using are in syringe packaged and designed for dispensing. We are using an Indium SMQ75 paste and current

Guys, Thanks for the input. Its a Opto-Electronic project I'm working on for a customer with a device on a ceramic substrate. Yes, I did learn from Indium that 007 is no-clean and has a high-solids content. They reccommended using TacFlux 010, which
