What are the functions of the components of the home appliance control board?

The use of household appliances in daily life has brought us a lot of convenience, and it is inevitable that we will encounter various small problems when using them. According to statistics, most of the problems actually occur on the control board, which is one of the essential components of household appliances and plays a decisive role in the quality of household appliances. Below, Langsheng Electronic Small Home Appliance Control Board Manufacturer will introduce you to it.

The small home appliance control board is mainly composed of solder pads, through holes, installation holes, wires, components, connectors, fillers, electrical boundaries, etc. The main functions of each component are as follows:

Installation hole: used to fix the printed circuit board.

Solder pad: The basic component unit of surface mount assembly, used for soldering metal holes of component pins.

Through hole: Through hole, also known as metalized hole. In double-sided and multi-layer boards, to connect printed wires between layers, a common hole is drilled at the intersection of the wires that need to be connected in each layer, which is used to connect metal holes for component pins between layers.

Wire: refers to the material used for wires and cables, and also refers to wires in industry. Copper film for electrical network connection of component pins.

Filling: Copper plating used for ground wire networks can effectively reduce impedance.

Electrical boundary: used to determine the size of a circuit board, and all components on the circuit board must not exceed this boundary.
