SPI Connector Black PlatingTM Advantages:

SPI Connector BlackTM is a proprietary duplex layered plating and blackening process for Electronic Connectors, Enclosures or other substrates that need to meet the stringent requirements of MIL-DTL-38999 or commercial specifications requiring Cadmium alternative coatings.

  • Compliant with WEEE, RoHS, ELV and other specifications that require Cd and Pb free deposits
  • Passes 500-750 hours Neutral Salt Spray testing on fully assembled connectors
  • Produces a matte black finish comparable to the reflectivity of Olive Drab Chromate
  • Produces a conductive coating that shows low contact resistance before and after corrosion testing

SPI Connector BlackTM is easily distinguishable from PTFE, Aluminum Electroplate and Cadmium/Olive Drab coatings. This ability to identify the coating from other cad alternatives is necessary to ensure that incompatible connections are not made in the shipyard, aircraft or vehicle assembly shops.
