Basic Knowledge of FPC/PCB Introduction to Circuit Boards 1. Flexible Printed Circuit Boards Flexible Printed Circuit Boards (FlexPrintCircuit, abbreviated as “FPC”) are printed circuit boards made of flexible substrates that can be single-sided, double-sided, or multi-layered. They feature characteristics of being lightweight, thin, short, small, high density, high stability, and flexible structure. They can not … Read more
Source: Old Thousand and His Friends Original Author: Sun Qian In the electronics industry, there is a key component called PCB (Printed Circuit Board). This is a very basic component, which makes it difficult for many people to explain exactly what a PCB is. This article will provide a detailed introduction to PCB-related knowledge, allowing … Read more
Editor’s Note PCB (Printed Circuit Board) is the supporting body for electronic components. Because it is made using electronic printing techniques, it is referred to as a “printed” circuit board. Before the advent of PCBs, circuits were made by point-to-point wiring. This solution had low reliability because as the circuit aged, line breakage could lead … Read more
Your smartphone has approximately 110 meters (about 360 feet) of wiring. These wires connect the camera, speaker, screen, wifi antenna, GPS, battery, fingerprint sensor, dozens of microchips, and many more components into one device, enabling all components to work closely together. A football field’s length of wiring is precisely integrated into your smartphone, but where … Read more
