You really are stupid. You don't need to reflow the lead-free parts. The
subject is using leaded solder for repairs, remember?


And to repair something with a damaged component, what do you do? Wave
your magic wand?
You REPLACE the part - which DOES require reflowing the parts. And
mixing the two solders is NOT recommended practice.
And if the RoHS compliant part you use for replacement is not tin
coated (and very many parts today are ONLY stocked in RoHS, and a
large percentage of them are NOT tin coated), you will not get proper
component lead wetting at leaded solder temps, and higher temps will
often cause flux problems (black scale from flux overheating).

Like I said - you can get lucky sometimes - but repair of RoHS
equipment with leaded solder is NOT recommended, or best practice.

Not smart either.

You are a HACK.
