Hello everyone, today I’m going to talk about an article about circuit board principles. Now let’s take a look!
1. The working principle of a circuit board is to use board based insulation materials to isolate the copper foil conductive layer on the surface, allowing current to flow through various components along a pre designed route, completing functions such as work, amplification, attenuation, modulation, demodulation, and coding.
2. The circuit board mainly consists of solder pads, through holes, installation holes, wires, components, connectors, connectors, etc., filling the electrical boundaries.
3. Common layer structures include single-layer PCB, double-layer PCB, and multi-layer PCB.
