Hi Steve, thanks for the info. I chased down the 2% silver paste because Alex G said it was the best. I got it from Farnell, about $25 US for a 25g syringe. I will try other options in the future. :o) I trusted Alex G as I knew he was doing some serious quantities with the SMT ovens. -Roman Steve Baldwin wrote: > > > The hardest part > > was finding the 2% silver solder paste syringe, > > and practicing using it. > > Roman, > > I've never used a silver solder paste to compare the two but I have > no problems with tin/lead in a Multicore RM10 flux/medium.
