Come together to demystify the mystery of multilayer circuit boards

About the production of multilayer circuit boards, first of all, according to the functions that need to be achieved by electronic products, drawing circuit schematics, there are special drawing tools, it is like understanding the individual components with wires.

Then, the PCB Circuit Board design software will generate a physical connection file based on the circuit schematic to connect all the components, the connection is very thin and thin copper skin in the actual production, you can conduct electricity.

So that a PCB circuit board is ready, and then send the ready file to the special multilayer circuit board production manufacturers for production, it is made into the actual circuit board.

But the multilayer circuit board made from the circuit board manufacturer is no components, it is only some wiring connections. It is just like an electrician wiring, leaving all the electrical locations that need to be connected, and connecting all the wires. The last thing we need to do is to install these components on it.

We need to use the components, solder to the designated location, then the entire multi-layer circuit board will form the actual working circuit, you can achieve the desired function.
