Notes from an AIM No-Lead Presentation ... Wave Soldering * May require a higher pot temperature than tin/lead: 255-265*C * May require a change in liquid fluxes to compensate for the poor wetting of some alloys and high thermal stresses of the wave

Would i be able to use the cast iron pot from my electrovert with out any problems? I thought the tin would dissolve the iron in the pot? This lead free thing is a headache!

Electrovert provides a lead free retro fit kit for your Econopak Gold machine...as long as you have a cast iron solder pot. $10K-$12K for the kit.

We have had expierience to convert our wave solder machine EPK1(1995g)with cast iron solder pot for lead free SN100.It runs about year and half now without problem.

Some companies claimed their lead free solders wouldnt attack stainless steel, frankly they do and they should not be allowed to get away with these claims. Lead Free does not attack Cast iron

It could be that the Sn96 has dissolved the Tin rapidly and gone for the Copper. What dwell times are they using with the irons? Probably better off using a Tin Copper alloy for reduced dissolution worth a try Cheers Greg

Sn corrosion effects were studied for stainless steels, coated stainless steels, titanium, cast iron, and other materials. This study can be found in the SMT Library under "Equipment Impacts of Lead-Free Soldering" Electrovert uses a Melonite coating

First, responding to your question � Several things on copper dissolution in solder are: * A 50um copper wire will dissolve in 60Sn / 40Pb solder at: - 200�C solder in 55 seconds; - 250�C solder in 20 seconds; - 300�C solder in 5 seconds; - 350�C so
