PCB encapsulation material
PCB potting is a protective process where a circuit board is encased in materials like epoxy, polyurethane, or silicone to enhance durability, insulation, and resistance to environmental hazards.
Epoxy Resin
Manufacturing Process of Copper Clad Laminate for PCBs
PCB board copper clad laminate is a substrate material used for making printed circuit boards, supporting components while enabling electrical connections or insulation. The manufacturing process involves impregnating materials like glass fiber cloth or paper with adhesives such as epoxy or phenolic resin, followed by lamination with copper foil and application of heat and pressure to create the final laminate.
