Developing precision connector materials to provide optimum physical and mechanical properties for complex connector designs is challenging. 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 the needs of new interconnection components, PMX has developed high precision alloys and coatings designed to work together to deliver outstanding performance. PMX alloys and proprietary 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 application and performance requirements. The hot dip plating chemistry can be based on 100% tin, tin-copper or a tin-silver alloy. Through secondary steps we can produce electroplated formulas involving copper, tin, nickel, or gold. Click here for complete technical data on our lead-free coatings.

Connector manufacturers select our lead-free 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

PMX lead-free 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.
