✦Basic product information：

05074-A-0122 05704-A-0121 A printed circuit board is a technique by plating a layer of conductive material (usually copper) on an insulating substrate and etching it into the desired circuit pattern. It can be seen as the skeleton of an electronic device, which enables the entire circuit to work normally by connecting various components and providing functions such as current, ground wire and signal transmission.

Single panel: One side of the board is covered with copper, the other side is not covered with copper, and the user can only wire and place components on the copper side.
Dual panel: Includes the Top Layer and Bottom Layer. The top layer is generally the component surface, the bottom layer is generally the solder layer, and both sides can be covered with copper and wiring.
Multilayer board: A circuit board that contains a plurality of working layers or power layers, generally referring to more than three layers of circuit boards. In addition to the top layer and bottom layer, it also includes the middle layer, internal power supply or ground layer.

05074-A-0122 05704-A-0121 Applications of printed circuit boards include almost all electronic equipment, from household appliances to industrial production equipment, from mobile communication equipment to computers and medical equipment and so on. Its main uses include:
Connecting components: Through its wire and pad, the electronic components are connected together to achieve circuit functions.
Provide electrical connections: A network of wires and electrical components on the circuit board can conduct current and transmit signals.
Support components: Provide a robust platform to support components and protect them from physical shock and vibration.
Optimal wiring: Optimize the wiring of the circuit to improve the transmission performance and reliability of the circuit.
Reduce size and weight: The electronic components are effectively integrated into a small board, reducing the size and weight of the device.
