PCB circuit board is also known as Printed Circuit Board, which can realize the circuit connection and function realization between electronic components, and is also an important part of power circuit design. Today, we will introduce the basic rules of layout and wiring of PCB circuit boards.

Via is one of the important components of multi-layer PCB circuit boards, and the cost of drilling holes usually accounts for 30% to 40% of the PCB manufacturing cost. Simply put, every hole on a PCB can be called a via.

With the continuous improvement of human requirements for living environment, the environmental issues involved in the current PCB production process have become particularly prominent. Currently, the topics related to lead and bromine are the most popula
