Is it ok to mix lead solder with lead free solder? I want to do some soldering on a PCB that was soldered with lead free solder but all I have is lead solder.

Thanks

it's going to explode.



in reality, the only thing that'll happen is your board wont be rohs compliant anymore (oh noes!), if it even was in the first place.

LOL

I figured it would be fine but at the same I was wondering if mixing the two solders would produce a weaker joint because the new joint is essentially a new alloy.

not really, lead free solder still has a little bit of lead in it anyways, it's not 100% lead free. it shouldn't matter.

Ooooo maybe you are concocting a new "Super Solder" that conducts electricity better than pure silver!!! WHOA!

Yes, it could produce a weaker joint. However, it would typically still be plenty strong enough, remembering that we aren't looking to create a mechanical structure out of solder, nothing with much stress on it should be held down by solder alone.
