Advantage of FR4 Black Anti-static Fiberglass Board


Application of FR4 Black Anti-static Fiberglass Board

Anti-static board possesses good anti-static effect that can be divided into local effect of product surface and overall effect of the whole product with equal anti-static value of every part, the former is suitable for making worktable, and the later is suitable for making moulds and fixtures and so on.

Black anti-static fiberglass board can be widely used in the construction of factory building (semiconductor, LCD, electronics, optics and medicine, etc.), shelter of equipment in the clean room, spatial partition of clean room, clean equipment, observation window and equipment cover, electronic test fixture, etc.
