Have you tried the same setup with your leaded paste? Your lf paste might have different cold slump characteristics.

You could shoot the engineer that designed them in without having a way to manufacture them. You could also try laser soldering or selective soldering.

Hi all, recently my company just bought a laser marking machine but the manuals are in chinese. Does anyone know what website that provide manuals for these kind of machine. I've tried the company's website itself but there is no support on manuals.

HOW did you change the temp? Stay that course till you achieve the temp you need. Try slowing the conveyor as well.

Sure, it's possible to transfer water soluable flux from boards to tray to boards with low residue flux. We have never heard of this try of problem.

Are you sure the anvil is coming up? You might try running a program w/o parts or boards (no continuity check) and watching to see if everything is moving when it should be. Do you use continuity checking? If so, what are the results?

You can try to see if GPAK could help you. They make custom tapes and feeders. I have never used them, but they have some interesting video clips on their site.

Try Seho http://www.seho.de/index.php?id=2〈=en . At one time they had a machine that ran at near 0% oxygen (all nitrogen)that would solder without flux.
