Tin-lead wave soldering using a lead-free machine | 13 February, 2006

Hello,

I know for sure that using lead-free technology in conventional tin-lead machines makes a lot of problems. But I wonder if we can use conventional tin-lead alloy and components with a lead-free machine!

Is it possible? Does this imply any special measures, precautions or modifications?

Thanks in advance and best regards...

If you're asking about wave solder machine, yes you can run Sn/Pb in a "Pb Free" machine. The concern is that when its time to run Pb Free you're going to have to remove all the parts from the solder pot to remove all the Pn/Pb solder residue from pot and all components. Then you'll be ready to load a Pb Free alloy into the pot.

Consult with your machine manufacturer.

Yes, it's fine - as Pete says you have to replace certain parts & either get the pot recoated or a new one. We ran a "Lead free" 6622C from Vitronics Soltec on Tin Lead, then it was cleaned up, recoated and loaded with a no-lead alloy with no problems.
