Contact plating material options for electronic connectors

Plug-in connectors are used in a wide range of different environments and must perform reliably and consistently. Connector manufacturers must therefore focus on many aspects to ensure a good quality product. This includes consideration of the shape of the contacts, the number of contact points, the normal force, relaxation of the base material and both the chemical composition and thickness of the plated contact surfaces. When choosing the right plating solution connector manufacturers must pay careful attention to numerous technical requirements and physical demands. Until today, there are many different contact surfaces for connectors available on the market. Every contact surface has its unique characteristics and its own advantages. This white paper will give a short overview over the contact system and common surface coatings used for electronic connectors. Furthermore, the focus is on a comparison between hard gold and hard gold flashed palladium-nickel (80/20), because in the field of ​​data transmission via electronic connectors these two coatings are the most common options used. Although this topic has been discussed earlier, there are still many questions. The respective characteristics and advantages of these two surfaces will be considered in more detail and confirmed by investigations done in the HARTING Quality & Technology Center.
