What is the standard of a good PCB board? Reasonable layout, sufficient power redundancy of power line, high-frequency impedance and simple low-frequency wiring. What kind of PCB design layout can reach the best heat dissipation There are three main sources of heat in PCB: heat from electronic components; heat from PCB itself; Heat from other parts. Among the three heat sources, the...

When assembling a printed circuit board (PCB), components are mounted onto the board through one of two primary methods: Surface Mount Technology (SMT) or Through-Hole Technology (THT). Each method has distinct advantages and is suited to different applications depending on the project requirements. This guide explores the SMT and THT assembly processes, their differences, and how to choose the right...
