I think OA flux left on the pot would quickly looses its activity and become part of the dross waste stream, and smoke stream for that matter. Also, if your wave is setup properly your selective pallets will scour (push) the top of the lambda wav

It's the same like asking wether you get a gold-contaminated solder pot when soldering ENIG boards. As long as the replenishment of dross is large compared to the intake of contaminant, the contamination level will stay within acceptable levels.

Dear all, As we know there is a high risk of reliability issue due to lead contamination during mixture of NLF component at LF wave soldering process. But we have the following feed back from one of our customer as follow: Concerning the risk of m

If the solder in the pot is to be replaced, the cost is very high. Is there any methods that could control the lead content to be low 1000ppm? Any methods what if the content is exceeded 1000ppm?

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

Isn't it funny how solder manufacturers are adopting a spec. limit of "not to exceed 1000ppm of lead content". Doesn't leave much room for the rest of the "process".

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

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?

That "C - it doesn�t matter" choice sounds good because it doesn�t give you a headache when profiling but it gives me a headache when I read the article in the current "newsletter" about profiling where I found this: "If soldering to gold over nick

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,
