A PCB is a thin board made of fiberglass, composite epoxy, or other laminate material. Conductive pathways are etched or “printed” onto board, connecting different components on the PCB, such as transistors, resistors, and integrated circuits.PCBs are used in both desktop and laptop computers. They serve as the foundation for many internal computer components, such as video cards, controller cards, network interface cards, and expansion cards. These components all connect to the motherboard, which is also a printed circuit board. High Temperature Masking Tape is an excellent heat resistance & chemical resistance acrylic adhesive single sided masking tape/film that is used for gold plating in FPCB manufacturing. It is easy to peel off (Less adhesion) means less contamination to adherend substrate. High Temperature PCB Plating Masking tape is a heat resistant single sided tape used for PCB plate masking. The product is a low adhesion means no residue after removal. It is laminated with PET Release Liner and can be supplied as die cut. Masking Tape with polyester film and blended silicone adhesive used for PCB masking and other high temperature applications. It is also high Temperature Masking Tape for PCB manufacture & Reflow process (Anti-static treatment). The product is laminated with Fluorosilicone release liner and can be supplied as Die-cut goods. As thermal problems come in a wide variety of shapes and sizes, so to must protective tapes. Polyonics understands the chemistry of temperature. How it works, how it affects materials, components and products. Most importantly, Polyonics understands how to engineer composite materials so they remain dimensionally stable at high temperatures and continue to provide superior performance.
