lead free 0603 wave soldering | 3 December, 2008

Is anyone wave soldering 0603 leadfree succesfully? We have no problems soldering them leaded, but lead free we see a lot of random skips and some shorts. We use SAC. We have tried different fluxes, flux settings, playing around with preheat, soldertime,etc., the basic stuff.

Are there any documents recommending/studying what can/can't be wave soldered lead free?

Every problem faced with (all) lead free alloys can be solved with 2 words �add lead� I'll keep it short don't want to sound like a broken record.

looks like my knowldge preceeds me again. I woud try a different flux. If it doesn't work - it will take a question mark away and your one step closer to total success.

you need to check your angle on this, can you measure and advise what you have cheers Greg York

The angle is a standard Soltec 7deg. We don't have the tools to measure this accuratly, but I do trust Soltec on this.

Great as most Lead Free machines have the wrong angle on them 7 degrees is correct. So you are still exiting the wave in the middle of the pot then.
