Circuit boards come in single-layer, double-layer, and multi-layer configurations. Multi-layer boards have multiple layers of conductive traces, allowing for more complex circuits.

[0003] For example, Patent Publication No. CN217721567U discloses a high-temperature-resistant multilayer industrial power supply circuit board. In this utility model, the fixing bolt passes through the adhesive base and abuts against the surface of the rubber pad. A limiting slider adapted to the rubber pad is provided at the side of the adhesive base corresponding to the rubber pad. When the installation length or width of the circuit board body needs to be adjusted, the adhesive base can be removed and adhered to the side edge to be extended. Then, according to the installation requirements during use, the rubber extrusion head can be adjusted by pulling the rubber extrusion head from the interior of the adhesive base. After adjusting the appropriate distance, the fixing bolt is screwed into the interior of the rubber pad to fix the rubber extrusion head. The rubber extrusion head can then abut against the edge of the installation location, thereby allowing the circuit board body to meet different installation and use requirements and improving the convenience of the circuit board body during use.
