So, why do you think that the requirements for accepting a solder connections would change depending on whether the connection is or is NOT visible?

David, you can beat around the bush interpreting criteria, but without X-ray you will not see anything. This is the way to go to inspect this solder joints properly. Criteria is 75% fillet and than you have circumference, air gaps in there....

Has anyone tried producing domed joints for high voltage corona reduction on a selective solder machine? I'm guessing it probably won't work due to gravity, but worth a shout. Thanks, Rob.

I hope someone would be able to help with this.

I think silicone mask is ok, This is so that after soldering, you can use these holes to fit other components later. This peelable layer is needed, unless you want to solder each component manually--From ALLPCB

cColor is NOT a measure of solder connection quality. It is a process indicator. So, you're being smart by trying to figure out whats causing he discoloration

Is anyone using the SC995E solder and if so what are the pro's and con's? And anyone using the Rel61? And what are the pro's and con's. I would love to hear the results. Thanks

Anyone have experience (good or bad) directly reflow soldering microSD card (Pb-free) to PCB. asking for a friend :)

BOT SIDE QFN DROP DURING TOP SIDE REFLOW; Bot & Top side solder profile temperatures are almost similar with a 5 Deg variation

We are looking into selective solder machines and would like any comments on the electromagnetic style pumps. They look much easier to maintain but do they perform well ?
