Blank circuit board refers to a substrate that has not undergone circuit design and production, usually made of materials such as glass fiber and resin. It is mainly used to make printed circuit boards (PCBs) and other electronic components, such as LED lights, smartphones, tablets, etc
Blank circuit boards are usually composed of three layers of materials: substrate, copper foil, and cover layer. The substrate is the main part, usually made of glass fiber and resin; Copper foil is a thin film on a substrate used to make circuit connection wires; The covering layer is a protective film that protects the copper foil and circuit.
A blank panel is a design without any buttons or sockets on the panel, mainly used in the following scenarios:
Covering the wiring junction box solves the problem of line branching and ensures the safety and cleanliness of wire connections.
