Lead-free??? You might see these kinds of problems with capillary action in t-hole items more-so than lead.

It all comes down to cost and reliability. Which order is up to you. You don't want to spend $100 fixing a $1 board.

Well, at that value point, I'd go with the hourly ( unburdoned ) high-skill rework/repair rate up to 50%-60% of the board value. If this is part of an integrated system ( in-house assembly ) repair to value ratio could go even higher.

Wow! How would it be possible to spend $700-$800 in labor to repair a single board? What are labor burdens these days? $30-$40 per hour at most?

How we can improved the Solder voids on QFN Packaging. Actually we adjust the time for solking to long . But is not affected. Pls advise. ThANK YOU

This may sound like advertasing, but I ran a DOE with five solder paste/flux manufacturers and somehow, the voids went away with the AIM solder.

The calibration was ok. When i switch off the back camera and use front one everything is ok. Is it true that when Topaz use back line camera after checking the components the machine rotates the components 180 degree?. Mark \

Hi! Try to make "R_AXIS_ACCURACY" calibration for all of FNC heads for back camera only. I met such problem on Topaz-X. There was clearly seen offset on 0.8mm pitch components. I simply calibrated all cameras for FNC nozzles and problem disappeared.

Hi Mark, This problem can be overcome by adjusting the camera brightness - Gain & Offset. I think the offset value is very high. Try reducing it.
