It seems to me that with you being the "creator" and all that should already know! I have only used HD in the past and am not really aware of any body else out there. Mortal Man

Hi Jessie, Wrong market - we print solder (or glue) onto boards in 3D, then place components into it, then put it through a very hot oven, for it to liquify, then solidify, fixing the components to the board. Good luck with your venture, Rob.

Thanks, but I need info on feeder manufactures which can provide a barcode label feeder. Any takers?

Try Max Edge. They're out of Tiawan, but have a pretty good operation. And I'm not a sales guy, just an end user.

Can BGA's really be reliably attached without adding any extra paste? Just use the BGA balls and tacky flux? We are interested in the Pro's and Con's. Seems like a lot of different opinions out there.

Yes, you can place a BGA in flux and get good reflow. However, depending on BGA type and size you should expect a yield loss due to coplanarity issues. Having the paste on the pad definately helps your yield.

There is no IPC requirement for reworking BGA with either paste or just flux. While we generally use flux only, general consensus is that both methods work equally well. Adding solder paste, while more difficult, should result in larger package stand

Agreed. You will find different part manufacturers have different coplanarity specs. In fact I have on supplier that calls out 7 mil max coplanarity. Then factor in board bow and twist and it becomes a real joy.
