Vacuum metallized polyester film
By depositing copper in a vacuum onto the film’s surface, copper metallized PET film features a high dielectric constant, outstanding insulation resistance, thermal insulation, and robust tensile properties.
The main difference between electroplating and vacuum metallizing is cost. Vacuum metallization is usually more expensive and has a higher process complexity than electroplating.
In a vacuum, the coating material is evaporated or sputtered and deposited onto the substrate to form a thin film. Since there are no air molecules to interfere, the coating material can travel in straight lines and form highly uniform layers.
EMI solutions consist of three main routes: EMI shielding, printed circuit board grounding and EMI absorption.
