Never Overlook the Importance of Line Width and Line Spacing in PCB Design

2026-05-21

To achieve high-quality PCB design, in addition to the overall routing and layout, the rules for line width and line spacing are also extremely critical, as they directly determine the performance and stability of the circuit board. Therefore, taking RK3588 as an example, this article introduces the general design rules for PCB line width and line spacing in detail.

PCB Line Structure

2026-05-21

The physical entity on which a circuit system depends is the PCB (Printed Circuit Board). The interconnection of components (including both electrical and mechanical connections) is realized through metallized traces on the surface of the dielectric or between dielectric layers, while traces on different layers are connected via electroplated vias.

What Are the Heat Dissipation Techniques for PCB Circuit Boards

2026-05-20

For electronic equipment, a certain amount of heat will be generated during operation, which causes the internal temperature of the equipment to rise rapidly. If the heat is not dissipated in a timely manner, the equipment will continue to heat up, components will fail due to overheating, and the reliability of the electronic equipment will decrease. Therefore, effective heat dissipation treatment of the circuit board is extremely critical.
