[pdf] This layer insulates the traces, prevents oxidation, and avoids unintended solder bridges during assembly. Beyond functionality, the finish type, whether gloss or matte, influences the board's visual appeal and surface characteristics. In the PCB board manufacturing process, matte finishing is a type of surface finish that makes a dull surface and non-reflective look on the. Matte finish has a microscopically textured surface that diffuses light, making it non-reflective. In contrast, a gloss finish has a smooth surface that reflects light directly, creating a shiny appearance. It is a strategic selection that impacts assembly yield, signal integrity, long-term reliability, manufacturability, and even environmental footprint.
