Tin plating of energy storage connector
Designers frequently ask what plating finish we recommend. There are numerous considerations to take into account (as evidenced by the variety of plating optionson most basic connectors), but the best plating finish is whatever meets your system requirements, at the lowest cost. In other words, make sure it works. Gold is generally specified for high reliability, low voltage, or low current applications. Gold is used in high cycle applications because it's. 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. Selective gold-tin plating is Samtec's most popular plating option because it provides designers with the best of both worlds. The contact area, the critical area where the contact interfaces the terminal pin and the signal is transferred, has the reliability of gold. The tail, which is. The distinction between gold and tin comes down to normal force. Gold requires a much lower amount of normal force compared to tin. Fine.
