We are making a socketed version of the boards, but it forces some compromises that will degrade performance. In talking to people (although admittedly most are rework vendors) the consensus is that with this small a part you pretty much need visio

make your silkscreen accurate and you do not need vision vision is the reason for the high cost of this equipment. A part like you mention can easily be done with a temp controlled heat gun and a fixed height stand (about 300 dollars total)to hold t

I'm with Dave on this one. In my opinion, it'd be much more cost effective to add an alignment legend. Speaking from experience, as I've hand placed many BGA's, all you really need to do is hit the pads. Even with Pb Free Chemistries, the part should

Ok, that's small - I think you may need a special semi-conductor printer for this - positional accuracy on a "normal" SMT printer is no more than 20 micrometres from memory. In my semiconductror fab days we were printing with a positional accuracy

Joshua, 100um is 4mil aperture. You should ask several stencil houses about the possibility to print that small amount of paste(type 6 paste is available now with very small solder spheres 5-15um diameter). Even applying small amount(thin layer of f

Minami vacuum reflow is easy to maintain air tightness, and oxygen can be reduced to 50ppm or less by filling N2 gas. And generation of oxide film can be suppressed, and production in low oxygen environment is possible. In addition to the air tightne

I have recently completed a HUGE screen-printing DOE. I used Taguchi methodology and man I got good results! Here is what I learned for what it's worth: (p.s. to the MPM apps guy I sent a copy to Tim Gillis, Lou Fuda, etc...) EFab vs. Laser: EFab
