How are components attached to a PCB?

Direct insertion is to insert the electronic Components pins into the PCB pad holes, and then pass through the tin furnace
The pins of the patch are of contact type, and the pads (soldering points) are corresponding to the pins of the patch components. The electrical principle is the same as that of the plug-in. They are all connected by mulit-wiring printed board copper foil. You guess it’s a computer motherboard. Computer motherboards are generally multi-layered (that is, there are at least 8-24  Layer Touch Activated Switch Circuits in the interlayer of the PCB, and each layer can be embedded with copper foil. The advantage of this is the surface The components can be made dense enough, and the physical circuit connections (copper foil) are all done in the interlayer.
