SPI connector black is an exclusive double-layered blackening and plating process for electronic connectors, enclosures and other substrates that have to meet commercial specifications that require Cadmium alternative coating or have to meet the strict requirement of MIL DTL 38999. SPI connector black can easily be detected from PTFE Cadmium/Olive Drab coatings and Aluminum Electroplate.
It is necessary to identify the coating from other cad alternatives to be sure that unsuited connections are not made in the aircraft, shipyard or shops for vehicle assembly. SPI connector black should be compliant with WEEE, RoHS, ELV and additional specifications that require deposits free of Pb and Cd. It should produce a coating that is conductive that displays low contact resistance before and after testing of corrosion.
Uses of SPI Connector Black
SPI connector black is used for rack plating for intricate geometries and shapes. It is also used in wire plating for parts of high volume, mid-size, selective plating, and intricate geometries. It is used extensively in-house quality and analytical laboratory for chemical analysis and atomic absorption, NDT, Adhesion per ASTM B571.
It can be used on parts up to 2 feet. SPI connector black passes 500- 750 hours neutral salt spray testing on connectors fully assembled. It has a matte black finish that can be compared to the reflectivity of Olive Drab Chromate.
Electronic Connector Coating Services
Electronic connector coating services can be an interesting process that needs finely refined expertise. The company has 90 years of experience in metal finishing and can provide the best metal finishing for electronics industry applications. Few companies involved in electronic plating can match their expertise in plating on semiconductors, vital electronic parts, connectors, and components.
Electronic connectors with coatings are used in computers, cell-phones, and televisions. Electronic systems are also used in controlling the operation of automobiles, airplanes, ships and other modes of transportation. One of the most important processes in the manufacture of electronic parts is electroplating which involves the application of a metal coating through electrodeposition.
Gold Plating in Electronics
Gold is a precious metal that is used in plating electronics. It is used in plating different electronic components. The metal is a little expensive but it offers stable and low contact resistance and strong protection against corrosion. It is mostly used in the manufacture of connectors, circuits, contacts, and semiconductors.
Nickel is mostly used to provide a basic coating when gold is used to plate electronics. The nickel acts as an added corrosion inhibitor by stopping rust from penetrating openings in the surface. Nickel also stops the diffusion of other metals like zinc and copper into the gold surface.
Summary - Painting for Electronic Connectors are used to plate connectors, circuits, contacts, and semiconductors to protect them against corrosion.
