Bob The actual process for converting from SAC305 to SN100C is pretty painless. Basic steps: 1) make sure your solder pot is at temp 2) de-dross 3) pull pumps/flow duct(s) and clean 4) purge pot of SAC material 5) remove any remaining dross/alloy i

We use Wondermask 2211 and we haven't had issues with the material creating gunk in the pot. You might want to call TechSpray and consult with a product specialist who can better advise you on what's best for your application. Rob mentioned the wave

We're using Sn100C at wave. Well, to be fair, in a static solder pot; as we don't have a lead-free wave machine in operation at the moment. We've had generally good experiences with the SN100. Good soldering; some blow holes, but, since we're usin

No, the thicker plating and need for very high quality drilling and plating is DUE to the higher copper dissolution rate and higher contact time. As to the Sn100C material, their claims seem to confirm a "lower" copper dissolution rate, but so does A

Dont't bother to answer real idiots! I can relate to a similar problem. We also use SN100C alloy and the solder pot get(got?) contaminated with the alloys from the SAC305! How can this be? Strange thing happens during the soldering process, and it o

I do not mean big, heavy transformers but rather small ferrite core transformers, with ferrites in the range of EF16 .. EF40. The weight of the lead and its percentage of the total weight is not the issue here. We simply do not want lead-containing t

One of the things that I have found is the "benchtop/lab" type waves (Low cost) do not perform very well except on the simplest of products, they are lacking critical design elements such as adequate preheat length, laminar flow nozzle design, etc.

We installed a Soltec Delta 3 a few months ago and have been trying to run with a VOC free no clean. We're using SN100C in the pot. We are spraying the material and have top/bottom preheat. Evaporation of the water in the flux is a bit of a stru
