PMX uses a system approach to designing connector materials and protective coatings. The elimination of lead from plating and coatings has resulted in some tin coatings that do not meet many of today’s requirements. To meet rigorous connector requirements, we have developed a comprehensive range of high precision copper alloys and coatings that are designed to work together to prevent corrosion and deliver a robust, dependable contact. For example, our connector materials and coatings have been used on automotive interconnects to achieve reliable performance during continuous operation at temperatures in excess of 140˚C.

PMX offers a variety of RoHS compliant electronic coatings that can be applied as a hot dip, by electrolytic plating or reflow. Our coatings are developed for specific applications. Our hot dip plating chemistry can be based on 100% tin and tin-copper. Through secondary steps we can produce electroplated formulas involving copper, tin, nickel, silver, or gold. These protective coatings are cost-effective, corrosion resistant, and provide good solderability. Click here for complete technical data on our lead-free coatings.

Connector manufacturers select our electronic coatings to meet a combination of specific properties and performance objectives such as:

• Low cost
• Low insertion force
• High temperatures
• Whisker mitigation
• High reliability
• High electrical conductivity
• Corrosion resistance
• Good solderability
• Uniform thickness
• Shock-resistant

Our protective coatings stand up to the challenges of harsh operating environments, high temperatures, numerous connect and disconnect cycles, vibration, and contact resistance. Contact us for more information.
