How a factory uses zinc-nickel plating deposits on computer parts – Technology Magazine

Posted on September 15, 2021 by Rochester Farmers Market

Some of these parts, especially copper heat sink fins, must be protected from corrosion as they operate. For complete protection factories should use electroplating to install zinc and/or nickel coatings on the entire surface of the copper components. The process of electroplating described in this video tour of the factory employs metal racks that conduct electricity for rack plating. Even though this process is more expensive than barrel plating, it provides a number of benefits including more control over the piece’s surface. The video below shows VGA slot covers and PCIe expansion slot covers. They are found within a wide variety of computer cases. They have to all resist heat and corrosion. When electroplating the parts, workers first place them on the conductive racks. Then the racks are submerged in a cleaner solution. When the parts are cleaned, they will be electroplated by applying a thin layer of nickel and zinc. These zinc-nickel plating deposits keep the components in perfect condition for their entire life span. bhwkc6kggt.
