PCB board layer identification skills

The substrate of the circuit board itself is made of a material that is insulated and not easily bent. The small circuit material that can be seen on the surface layer is copper foil. The original copper foil is covered on the entire circuit board, and is partially etched away during the production process, leaving a small line of mesh. These lines are called wires or wires and are used to provide electrical connections to the components on the board. Usually the color of the PCB board is brown or green, which is the color of the solder resist paint. It is an insulating protective layer that protects the copper wire and prevents the part from being soldered to the wrong place.

Main Design Process of PCB

In the design of the PCB, in fact, before the formal wiring, it has to go through a very long step, the following is the main design process:

PCB basic manufacturing process

The PCB manufacturing process begins with a "substrate" made of Glass Epoxy or similar material.

Basic knowledge of printed circuit boards

Printed circuit boards (PCBs) appear in almost every electronic device. If there are electronic parts in a certain device, they are also mounted on different sizes of PCB. In addition to fixing various small parts, the main function of the PCB is to provide electrical interconnection of the various parts. As electronic devices become more complex and require more and more parts, PCB wiring and parts are becoming more and more dense. Bare boards (without parts) are often referred to as "printed Wiring Boards (PWB)."
