Hello davide, the biggest advantage you'll find with a complete N2 tunnel is the minimization of oxidation during board preheating. Using only an inerted solder pot allows the oxidation to build up throughout the preheat stages and introduces contami

I know this has been dealt with in the past but I couldn't dig up anything in the archives. If I'm soldering a 0402 lead free component with 63/37 solder is this a problem. Also lets take the opposite. If I'm soldering a lead bearing 0402 with lead f

Target those specific parts/leads with a thermal-couple and a mole and try to get the peak reflow temps up to 225 C. It's not a cure but it will improve the apperance of the solder joints.

I was wondering if anyone has studied the effects of tin lead solder in the wave. If we leave the same solder in the solder pot, how many COMPLETE cool downs and start ups can the solder go through before it begins to break down? Please let me know
