Dr. Lee, For lead-free wave soldering, we are recommended to use SnCu0.7, why not 0.8 or more ?? Since SnCu0.7 has eutectic melting point at 227 deg C, does it mean with more Cu or less Cu, the melting point will be higher ?? Also, in lead solderin

We are looking for a used or new wave machine must be able to do lead free solder. Does anyone have contact information in the Chicago, il area for used wave soldering machines? Thanks for any help we can get.

Jerry, In your initial post you give 260C as solder pot temp if you�re not using lead-free I would reduce the temp to 250C this will also reduce oxidation rate.

Agreed, I just bought a Electrovert Vectra Elite and have been very pleased with it thus far. I got the dual pot option for lead free changeovers and that has worked great. I can change pots in under 5 minutes, not counting the time to warm up.

Hi all, we're preparing for the switch to lead free and I was wondering how dangerous/harmful to our new wave oven it would be to run tin lead parts through the no lead wave. Will the lead build up and cause issues?

Yeah, adopting is the right word. In this new lead-free era spec.'s are made to stay within the scoop of the RoHS directive. The driving force for spec.'s should be reliability. Did you see any impurity level spec.'s yet in wave soldering for Cu, Au,

We have carriers that we use in wave flow solderers that are machined specifically for each board out of ESD composite. I was wondering if anyone knows about lead contamination of this material and the cleaning of composite? I know that it is a p

Lead free is not define as NO lead and "a maximum concentration value of 0.1% by weight in homogeneous materials for lead shall be tolerated." Check below link. So replaced your solder from the pot when exceed 0.1%. http://www.leadfree.org/files

Your friendly wave guy here, check out Aim solders web site. click to the right where it says lead free. There is a complete discussion on what can occur. http://www.aimsolder.com

Do present reflow and wave solder equipment currently processing tin-lead process need to be replaced when migrating to lead free process ? Is there any equipment (reflow or wave) out there capable of processing both leaded and unleaded processes wh
