We had a similar problem with lead-free through-hole components. We baked those baords to remove the residual moisture and everything went to 100% pass - defect was gone. Couldnt hurt to try a sample run while you decide if the PCB holes need to be

We have GSM1 running on USOS V1.4.14. Is there a way to change default light levels for PEC (down looking camera) during feeder teach? Whatever I tried, it is always set to some default level... - Dejan

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?
