Check out Indium Solder. They have an evaluation board "from Hell"!!! I believe they sell it for eval purposes...will supply cad data for stencil as well as pcb's for print test. I was stunned at the complexity. Hope this helps

Try out the component print stations apply solder to the BGA instead of the board, works perfect! Let me know if you need more info! Marco

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.

Yes, Loctite 3880. It works out at about $160 for a tube of 30ml. It can be dispensed or printed. We found you needed a lot less than with solder as it doesn't wick or spread much.

Are you seeing solder balling on your discretes when you print 1:1? Are you washing your boards?
