What’s the difference between gold plating and tin plating?

Surface of the connector terminal is tin-plated and gold-plated, both of which are electroplated. Nickel base is applied first, and the surface is tin-plated or gold-plated. However, some customers require gold plating on the soldering part or on the entire contact. Different plating thickness, the electrical conductivity will be different, and the storage period is also different.

Kunshan Connector Electronics Co., Ltd.(CNT) defaults to the overall gold-flash plating.Warranty for gold plating is 1 year, and warranty for tin plating is half a year.

Regardless of whether the connector is gold-plated or tin-plated, the function is to protect the copper material, prevent oxidation, and get stronger electrical conductivity.

Surely, different plating methods also have differences, the main differences are:

Tin plating has better solderability

Gold plating has better conductivity.
