Yes the part is reworked. It solders when it's reworked.

By profile (profile has not been changed) are you referring to the oven zone settings or the actual charted profile of a trip through the oven as recorded by a thermal profiler? Some ovens will continue to function without warning as long as temps

OK, part touching paste before reflow? Check part. Maybe bad plating. Check reflow profile by slowing conveyor.

Questions are: * So after you spot one of these leads sitting on a nice pillow of solder, what happens? * Do you rework the part? * Does it take solder? * What do you do to make it take solder, if it does take solder?

That's your clue. Your reflow is running ~240*C and your soldering iron is running ~370*C. Dial-up the heat.

Check for coplaner leads if this just exists at reflow process, i.e. look at part before oven, turn on 3D at placement machine. If you see after wave solder, the wave could cause coplanarity issues on top as well if you are going slow enough to refl

Is the solder reflowing on the pad but not wicking up the lead, or does there appear to be insufficient solder to wet both, or is it not reflowing at all, or.....? Have you verified your profile? What is the condition of your paste (expiration date,

Since Vic posted me privately and asked for the SIR test parameters I spoke of in my other post, I thought I'd respond on the forum. Ok, here they are, per Joe Keller--Solder / process consultant AKA Manko..... This is an accelerated SIR / dendrite
