Connector Degradation Mechanisms—Corrosion Part II

If connector manufacturers had the luxury of completely plating the contact springs with, say, five microns of gold, corrosion would not be an issue in connectors. Cost effectiveness, however, dictates much thinner platings—0.25 to 0.75 microns are typical, with the platings being applied only at the contact interface itself, selective plating.

Connector Plating FAQs

What is the typical thickness of these connector plating options? With tin plating, Samtec recommends at least 100 µ" of tin plating on the solder tail, and in many cases, greater than 100 µ" in the contact area. Some specifications don''t have a top end for tin plating. Because tin is inexpensive, we recommend 100 µ" minimum.

You may have already read about my 50:50:50 rule when it comes to the choice using tin plated surfaces versus gold plated surfaces in connectors. This rule says tin is the more economical solution if you have less than 50 contacts (mating forces), if you can live with 50 mating cycles (contact normal forces), and if you do not expect less than 50 milliohms contact resistance over

6 FAQs about [Tin plating of energy storage connector]

Is tin plating better than gold?

Tin is a lower cost alternative than gold, and has excellent solderability. Unlike gold, tin is not a noble metal. Tin plating starts to oxidize the moment it’s exposed to air. So a tin plated contact system requires greater normal forces and a longer contact wipe area to break through this oxide film. Check out the brief video below.

Why is there no tin plating on gold connectors?

You typically don’t see tin plating on these small connectors because it’s difficult to generate the appropriate amount of normal force. With gold, because it’s a noble metal and does not react with contaminants and pollutants in the atmosphere, you can go with less normal force, like 30-40 grams.

What is tin plating used for?

Tin is used for applications with fewer cycles, it’s less expensive, and it holds solder. Selective plating, with gold in the contact mating area and tin on the tail, is usually the best option. Questions on Plating?

Should we use gold or tin plated connectors?

Fine pitch connectors do not have the space for a relatively large, thick contact beam with high deflection; this is needed to generate the normal force tin required in tin-plated contacts. Therefore, due to physical size constraints of microminiature connectors, gold is often the only choice available. In other words, we would use tin if we could.

Does tin plating need a lot of force?

The short answer is yes. With tin plating, the general guideline is 100 grams of normal force per mated contact to achieve a gas-tight connection. Oxides can potentially build to the point where there are electrically resistive layers on the surface finish of tin. To make a good connection you need enough normal force to break through that oxide.

What are the limitations of tin plated connectors?

Other limitations of tin-plated connectors include limiting its use in high frequency applications such as radio frequency circuits. Tin plated connectors should be limited to low-frequency applications to limit the signal attenuation (more conductive platings are recommended for high frequency signal transmission applications).
