I am wanting to move towards surface mount components and reflow, so that is why I thought I'd do some experimenting to see what I could do with something along these lines. I was looking for an electric skillet at all the thrift stores near here ... apparently they sell quickly when they get one. Finally one store had this electric burner, so I decided to give it a try. Clearly, I need to do some more experimenting with the temperature settings ...

I fluxed the board, heated it, dabbed on some solder, and brushed it out. Worked great ... except for the small problem of over cooking the board!
I haven't tried the tinning part, but I've soldered SMD parts using an alu frypan over a gas flame - no board discoloration, take it off when all the joints look like they've gone shiny.
