Briefly describe the development trends of printed circuit boards
2026-09-05
On the insulating substrate, conductor patterns are printed using the printing method to form the electrical interconnection lines. In early electronic devices, electronic and electromechanical components were mounted on metal sheets as the base, and electrical interconnections were achieved through wires.
What is the compatible design of a circuit board?
2026-09-04
Electromagnetic compatibility refers to the ability of electronic devices to function coherently and effectively in various electromagnetic environments. The aim is to enable electronic devices to both suppress various external interferences and operate normally in specific electromagnetic environments, while also reducing the electromagnetic interference that the devices themselves may cause to o……
Introduction to simple circuit board protection packaging
2026-09-03
In order to seal a certain part of the circuit board or a smaller circuit board to prevent water vapor and foreign substances from entering and affecting the performance of the circuit, many electronic enthusiasts use wax or asphalt as sealing materials to protect the circuit. In fact, wax and asphalt as encapsulation materials are not good and have many disadvantages. However, the effect of "soft……
The composition structure of the circuit board
2026-09-02
The circuit board is mainly composed of pads, vias, mounting holes, wires, components, connectors, fillings, electrical boundaries, etc. The main functions of each component are as follows:
Pads: Metal holes used for soldering the pins of components.
Via: There are metal vias and non-metal vias. Among them, the metal vias are used to connect the pins of components between different layers.
