Gold metallization system
WebJan 17, 2024 · Vacuum metalizing, also called vacuum metallization, is a process that allows creating a metallic layer on metalized parts or a substrate and is a form of physical vapor deposition (PVD). It coats a metal (such as aluminum or copper) onto a non-metallic substrate by evaporation. The evaporation of the metal occurs by feeding a metal wire … WebThe thin films of gold which are applied so extensively in electronic devices are normally deposited over thin films of other metals in two, three or even four component …
