In 1880, the Census of Manufacturing recorded 570 employees. Competition increased during this period, especially in LaSalle-Peru, with the arrival of Illinois Zinc Company in Peru, the Mineral Point Zinc Company in DePue, and the Collinsville Zinc Company near St. Louis. Lanyon and Company and Thomas Kinsman also ran small smelters in LaSalle.
Electroless nickel immersion gold (ENIG or ENi/IAu), also known as immersion gold (Au), chemical Ni/Au or soft gold, is a metal plating process used in the manufacture of printed circuit boards (PCBs), to avoid oxidation and improve the solderability of copper contacts and plated through-holes.
Patents relating to Galvannealed wire were obtained by the Keystone Steel and Wire Company (Peoria, Illinois, USA) c. 1923. The company used the name "Galvannealed" as a brand name. [7] The key early patent was US patent No. 1430648 (J.L. Herman, 1922, Peoria, Illinois, USA) "Process of coating and treating materials having an iron base". The ...
The chosen content of zinc depends on the required productivity and part configuration. High zinc improves the bath's efficiency (plating speed), while lower levels improve the bath's ability to throw into low current densities. Typically, the Zn metal level varies between 20 and 50 g/L (2.7-6.7 oz/gal). The pH varies between 4.8 and 5.8 units.
Gold plating is often used in electronics, to provide a corrosion-resistant electrically conductive layer on copper, typically in electrical connectors and printed circuit boards. With direct gold-on-copper plating, the copper atoms tend to diffuse through the gold layer, causing tarnishing of its surface and formation of an oxide and/or ...
The plating industry received a big boost with the advent of the development of electric generators in the late 19th century. With the higher currents available, metal machine components, hardware, and automotive parts requiring corrosion protection and enhanced wear properties, along with better appearance, could be processed in bulk.
Black nickel plating was developed around 1905, and between the two wars, black chrome plating (first German patent 1929.GP 607, 420), which saw wider use only from the mid-1950s. [14] After the First World War, the first procedures for anodic oxidation and coloring of anodically oxidized aluminium were developed (1923, 1924.DRP. 413876).
