Are there specifications or recommendations for electro-deposited tin-lead plating thickness on austenitic stainless steel that would provide a shelf life of 1 year? 6 months? Would 2 to 3 microns (78 to 118 micro-inches) 90/10 tin-lead over 1.27 mi

Once you have selected your plating based on electrical and physical requirments, you should know that there is an inexpensive plastic storage packaging developed by Lucent which can keep any platings solderability from degrading for up to 10 years o

Your 316L stainless steel pot will not contain lead-free solder, over the long term. We'd bet that our solder machine equipment manufacturer will "swap" you a lead-free solder compatable pot for your current pot.

Hi, There are many companies shifting lead free solder wave. My question is can anyone give me idea if we can still use our old solder wave machine for lead free eventhough the solder pot is stainless steel 316L? Our solder bath has titanium nozzl

Hi, I think that the time depends on the type of stainless steel, temperature and solder alloy. For example, one of our machines is delivered with 316 stainless pot and alloy SnNi. It worked six months (120days*16hours = 1920hours) and aft

Proy, Another issue is what exact formulation of SAC is used. Much of the SAC305 being used in Asia contains phosphorus, which is added in an attempt to reduce the heavy drossing that SAC305 produces. Phosphorus acts as a flux on steel so will increa

A highly activated flux will allow intermetallics to form, because the hydrogen halide gas that formes at operating temperature will react with the refractory nickel oxide. Refractory nickel oxide is what makes SS "stainless". This will be worse wit

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

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
