PCB 板本身的基板是由绝缘隔热、并不易弯曲的材质制造而成。表面可看到的细小线路材料是铜箔,原本铜箔覆盖在整个PCB 板上,而在制造过程中部分被蚀刻处理掉,留下来的部分就变成网状的细小线路了。这些线路被称为导线或布线,并用来提供 PCB 板上零件的电路连接。通常 PCB 板的颜色都是绿色或是棕 PCB board itself is insulated from the substrate, and not easy to bend made of material. The surface can see the thin line material is copper foil, the original copper foil covered in the entire PCB board, and in the manufacturing process is partially etched away, the remaining part of the mesh becomes a small circuit. These wires are called wires or wires and are used to provide electrical connections to the components on the PCB. The color of the PCB is usually green or brown
