| Another basic soldering question. I notice that lead-free solders have become required for plumbing applications due to legislation. In a local hardware store, I noticed the existence of lead-free solders (based upon tin-copper I think) with a me

Hi Grant, You definitely have a pre-heat problem and not a flux problem. Pallets together with the BNC connectors put a large thermal demand on your pre-heating. 3 zones would be a good investment even with leaded solder due to the high thermal dema

We are building class 3 products, using no clean on wave and selective solder machines. Both processes are producing micro solder balls between the leads of through hole components. I have searched the site and haven't found any recent threads on h

Hi, Very funny, and I feel so much better not because of your advice, but because your a Dr Dr PhD, and we all know thats more important than experience! Seriously though, so you think we should be ok with the zones we have? We are not sure, and so

Dear all, Recently we encountered some functionality failure when using lead-free component(Sn99.3/Cu0.7)at SnPb(Sn63Pb37) wave soldering process. Can lead-free component use at non-lead free process? Any input/idea are much appreciated. Rgds

Hi, What worries me is that a lot of people speak about what they have heard, but there is no firm facts on exactly what the situation is. I did a seminar on lead free a while ago, and was told that going lead free on the components while running l

Hi All, The change over to lead-free is as easy or as difficult as you want to make it The big problem I see with this lead-free transition is that there is no benchmark of acceptability and no defect data (yet) related to visual appearance of a sol

Hi "theSaint", We are using SN100C in our wave solder machine. As far as the solder itself, the wave process follows pretty much the same concept as leaded solder. You bring the assembly temp to 90 C or more before the actual wave. Sometimes for mul

Quick Question! We have an assembly that we're building for a customer that will have to be soldered via a Lead-Free Wave Solder. We do not currently have a Lead-Free Wave Solder in house. Does anyone know of a company that may be able to provide thi
