Thank you all for your input. The MF300S Multicore flux is rated for lead free. There is not much dross or contamination. We are using nitrogen. I've tested the boards with the curing test of IPC-TM-650. I think you're all right about the preheat.

As someone with a LOT of experience with the "low cost" alternative alloys, primarily SACX, I have one simple question....Are these shorts a new phenomena? WAS your process in control, and all of a sudden it's not? If the answer is YES, take a look a

I recently had the same problems, solder bridges on every thing I made, different customers boards, etc. I wave with no-clean flux. As I sorted out problems (pin holes, blow holes, splatter, etc.) I found a lot of variable factors. I changed flux,

As long as your operator is grounded, a pair of welders gloves is fine. The leather kind do not build up static and do last a while. If the same pair of gloves is being used for dedrossing the wave, pay special attention to loose fitting gloves. I
