I am new to wave soldering. Any information is greatly welcomed. Here is the problem. After soldering the boards they have a film on the bottom of them and sometimes a white powder looking substance. I have tried decreasing the amount of flux on

Hey all! The wave solder warrior is back. I have found a flux which leave almost no residue (the least yet), but because of its super low solids content I absolutely cannot get topside fillets. The multi-layer, two sided board is on a pallet w

Stainless steel can NOT be soldered with the solder that is used in electronics, be it Sn63 or SAC305. I have 1st hand experience in this. Solder will NOT wet to it no matter how much flux is applied, or what type of flux is applied. Again, I have

Another thing I'm curious about. What is the "functional purpose" of soldering stainless? Solder coatings generally prevent oxidation on surfaces, but why would somebody solder STAINLESS? Stainless, by nature, is resistant to rust, and hence, oxid

Q1: Can Stainless steel be soldered? A1: Yes, stainless steel can be soldered. Q2: If yes, is our normal process adequate? A2: We know nothing about your normal process. Common flux used in routine soldering will not step-up to the requirements nece

As Dave said stainless steel can not be soldered using fluxes designed for electronics. The only way this could be done is to spot plate copper or tin where you want to make the solder connection.

Good move. Again, stainless can NOT be soldered with standard materials used in electronic manufacturing, as everyone agrees in this thread. Additionally, the physical properties of stainless have to be altered in order for soldering to take place.

Recommended procedure for soldering stainless steel [Atlas Steels Australia]: * Surfaces must be clean and free of oxidation. * A rough surface improves adherence of the solder, so roughening with grinding wheel, file or coarse abrasive paper is reco

Patrick, thnx for your info. The tabs will be soldered on a PCB pad just like an SMT component. Will let all know once I have some more info.

might try solder-less through hole connector technology for your SS tabs- the pins are barbed and it is pressed into place.
