Today we will explain some word abbreviations, like what is PCB, SMT, SMD, I/O, etc. What Is PCB? PCB stands for Printed Circuit Board. It is a crucial part of electronic devices and systems, providing the platform for electronic components to be mounted and interconnected. Here are some key aspects of PCBs: Function: PCBs serve as the backbone of electronic circuits, providing electrical connections between various components such as resistors, capacitors, and integrated circuits. Structure: PCBs are made up of multiple layers of conductive tracks, pads, and non-conductive substrates. The

The basic performance of electronic connector can be divided into three major categories: mechanical performance, electrical performance and environmental performance. 1. Mechanical properties In terms of connection function, plugging and unplugging force is an important mechanical property. Plug-in force is divided into insertion force and extraction force, and the requirements for the two are different. There are regulations on the maximum insertion force and the minimum separation force in relevant standards, which shows that the insertion force should be small, and if the separation force is too small, it will
