Quelle est la différence entre SMD et NSMD ?

Whats the Difference Between SMD and NSMD? SMD and NSMD are two types of semiconductors. While their pads are similar in size, NSMD components have smaller dimensions. In contrast, SMDs can be moved by the soldering iron, while a through-hole component can be mechanically secured prior to soldering. NSMD pads are smaller There are several […]

Les défauts les plus courants des circuits imprimés et leurs solutions

The Most Common PCB Defects and Its Solutions There are many problems with PCBs, but some of them are less obvious than others. These problems are called implementation failures and require specialized knowledge to diagnose. For example, Electrostatic discharge, Chemical leakage, Lifted pads, and component shifting are all possible causes of failure. To identify the […]

How High Thermal Conductivity PCB Material Will Solve the Heat Dissipation Problem

How High Thermal Conductivity PCB Material Will Solve the Heat Dissipation Problem PCBs, also known as printed circuit boards, are layered structures made of copper foils sandwiched between glass-epoxy layers. These layers serve as a mechanical and electrical support for components. The high-conductivity copper foils serve as the conductive circuit in the PCB, while the […]

2 Notes sur la rétro-ingénierie des circuits imprimés

2 Notes on PCB Reverse Engineering Computerized tomography A computerized tomography is a powerful tool for reverse engineering PCBs. This technique uses x-rays to take images of the inside of a circuit board. The resulting image can be used to reconstruct the board’s structure. Computerized tomography has several limitations, however. Its field of view is […]

How to Know the Surface Finish From PCB Color

How to Know the Surface Finish From PCB Color If you’re wondering how to know the surface finish of a PCB, you’re not alone. The color of a PCB can reveal its surface finish. You may also see a color designation called ENIG or Hard gold, Silver, or Light red. Regardless of what you see, […]
