Latest Patents
Joseph R Ranalli holds a patent for a "Stripped gold plating process." This method is designed for fabricating metallurgical contacts that facilitate thermocompression bonds to a metallized ceramic substrate, which is essential for mounting and electrically contacting semiconductor chips. The process involves placing a nickel layer on the metallized portion of the substrate, followed by an immersion layer of gold. The gold immersion layer is selectively removed from specific locations where thermocompression-bonded contacts are required. This removal is achieved using a chemical stripper, after which heavy gold is electroplated onto the desired locations. The assemblage is then heat-treated before the placement of the thermocompression-bonded contacts. Joseph R Ranalli has 1 patent to his name.
