Multi-layer PCB is a circuit board composed of more than two layers of electrical layer (copper foil layer) superimposed on each other. The copper layers are bonded together by layers of resin.

Nowadays, high frequency electronics are of great concern, especially in remote systems. With the rapid development of satellite communication, data items are developing towards fast and high frequency.

High frequency PCBS offer a wide range of features. Knowing these features will help you understand these PCBS. These printed circuit boards are called high-frequency PCBS because of the characteristics they provide.

Printed circuit board (PCB) is a board made of insulating and heat-insulating materials with a certain strength, which is fixed in the circuit and provides the connecting circuit between various components.

Why does the resistivity of semiconductor go down with temperature？Between the conductor and semiconductor resistivity difference is due to the different density of charge carriers.

PCB multilayer board refers to the multilayer circuit board used in electrical products
