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?

Replace it, moron.

You REPLACE the part - which DOES require reflowing the parts. And
mixing the two solders is NOT recommended practice.

You're obviously clueless. For pretty much anything other than BGAs you use a
soldering iron. Even for them one can do a reflow of the one part, rather
than the entire board. They have tools to do just that.

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).

Complere nonsense. Almost *all* parts are tin plated.

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

You're absolutely clueless.

Not smart either.

No, you're not.

You are a HACK.

No, I are an engineer. I do this stuff every day.
