If you don’t want to miss my updates, remember to click the top right corner – view public account – set as a star, and give me a star. Simple PCBs often only need to add a few elements to transform them from mere PCBs into something more. They can become “Kung Fu kids” or … Read more
Author: Da Xu Zi Source: Xueqiu 01 PCB Industry Scale、Development Trends and Introduction to Downstream Applications 1、Industry Scale PCB refers to printed circuit boards formed by connecting points on a general substrate according to a predetermined design，its main function is to connect various electronic components into a predetermined circuit，acting as a relay transmission。 The global … Read more
1. The process edge serving as the transmission edge of the PCB should leave a width of ≥6mm, and there should be no components or solder points within 10mm from the edge on both sides; Wiring depends on the installation method of the PCB. Generally, PCBs installed in a guide groove should not have wiring … Read more
Today, I watched a video that was an official promotional video from an Indian PCB factory posted on YouTube. I don’t know why YouTube recommended this video to me, but it captivated me instantly. Just to clarify, this isn’t about being captivated by a girl. After watching the video, I slapped my thigh several times … Read more
Copper foil is the main material used in PCBs, primarily for transmitting current and signals. The copper foil on a PCB can also serve as a reference plane to control the impedance of transmission lines or as a shielding layer to suppress electromagnetic interference. During the PCB manufacturing process, characteristics such as the peel strength … Read more
PCB (Printed Circuit Board) is a printed circuit board that can be classified according to the number of conductor layers. It can be divided into single-sided boards with copper on one side, double-sided boards with copper on both sides, and multilayer boards with multiple copper layers. Multilayer PCBs are usually composed of several double-sided copper-clad … Read more
Remember when I first did PCB Layout, multi-layer board prototyping costs were very high, and the delivery time was about seven or eight days. Due to cost and time considerations, I often only considered using double-sided boards for routing. Then, holding many design rules that would often “conflict” with each other or experience-based rules circulating … Read more
The main conductor material used in PCBs is copper foil, which is used for transmitting signals and currents. At the same time, the copper foil on the PCB can also serve as a reference plane to control the impedance of transmission lines or as a shielding layer to suppress electromagnetic interference (EMI). Additionally, during the … Read more
In hardware design, PCB design is a very important and indispensable step. For some simple products, PCB design may simply involve connecting all components and networks accordingly. However, for high-speed circuits and RF circuits, the design of the PCB directly affects whether the product functions properly and whether it meets market requirements. Below, I will … Read more
