Comments and Questions
Many companies use lead-free wrongly, they expose the solder to too long wetting times thus rendering usual lead processable flux useless.

They process lead free at temperatures that are rightly higher but it is the dwell times that are greatly extended and do not need to be. Keep dwell times down to 2 - 3 seconds in the wave and you will see that normal fluxes can be used very easily.
