There are many kinds of coating technologies for vacuum coating machine. Simply speaking, in vacuum environment, film particles are emitted by evaporation, sputtering and other methods, and deposited on metal, glass, ceramics, semiconductors and plastic parts to form various coating layers required by customers. The most common technologies in daily life are vacuum evaporation technology, sputtering coating technology, ion coating technology, etc. The following is a brief introduction of vacuum technology, hoping to help you:
Vacuum evaporation plating: The principle is to heat the film material with an evaporator under vacuum conditions to vaporize or sublimate it, and the evaporated particle stream directly shoots at the substrate, which is then deposited on the substrate to form a solid film. Evaporation also includes electron beam evaporation, resistance evaporation, induction evaporation, etc
Sputtering coating: under vacuum conditions, connect high-voltage electricity to the cathode, stimulate glow discharge, and positively charged argon ions impact the cathode target to eject film particles, which are deposited on the substrate to form a film.
