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?

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/LF_3-0_2.pdf

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?

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".

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, Ni, Zn, Fe etc. in lead-free, or are these impurities not important anymore? These metals are dissolving about a 100 times faster in lead free compared to leaded alloys. The European government with the help of sales people does an excellent job in brainwashing and makes us believe we have been chasing ghosts for the last 30 years. A minority can only rule when creating chaos and confusion and this is exactly what is going on with lead-free.

Just wanted to state some facts, because no clear answer is available in lead-free "yet"

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
