Tin verses SS
Tin verses SS
(OP)
I need to put a bunch of springs up against tin soldered pads. Stainless is being pushed in this regard. You guys see any issue with this? I suspect it won't be a problem.

RE: Tin verses SS
Here are two minor concerns.
One problem that I envision is that the springs will move a little metal in the landing area.
If this is pure tin there is a small possibility that the tin will oxidize a little in the contact area.

Check out this bi-metallic corrosion table its suggests you might have a corrosion problem if there is any electrolyte substance present.

fox; Thanks for that table. It does show some reason for concern... dang! These joints could have some high humidity associated with them occasionally. Perhaps I need to consider nickle plated springs.

RE: Tin verses SS
A possible alternative to plating the springs, would be to introduce an end cap over the spring that eliminates the possible corrosion problem between the stainless and tin.
Although this might cost more than plating, just something to consider.

If you are concerned a small plastic shim between the two might be less trouble than platting.
