Bill, I would go with the second piece of advice by leaving a little film of solder paste on the screen. This is good advise if you are using a lookup/look down type of vision centering. Like on MPM and newer Fuji. On older Fuji GSP2/3 style printer

Does anyone have experience placing a Pinrex 2mm 2x20 SMT header. The dimensions of the part are as follows: length 40mm (1.58"), width 6mm (.236"), height 5.35mm (.211"), pitch 2mm (.079"). If so, what type of centering are you using? Any advice

I've had alot of success with the solder pastes from ESP in Rhode Island. They have great shelf life and are easy to print | I'm currently planning to do an evaluation of RMA flux solder pastes for mil type applications. Does anyone have any suggest

Hi Tim, 8-mil huh? Boy, that's getting down there...you know, placing 8-mil is one thing, but printing solder paste on 8-mil pitch is another. Most of the time when I've seen 8-mil pitch on a board it's been attached with hot-bar...but I guess
