The common drilling holes in PCB are through hole(VIA), blind hole and embedded hole. What’s the meaning and characteristics of these three kinds of holes? Via(Through Hole) What is Via? Via is a common hole and used to direct or connect copper foil lines between conductive patterns in different layers of the circuit board. Because PCB is formed by many copper …
In PCB design, we always encounter this and that problem. This article summarizes 8 frequently asked questions you might come across. We discussed, and hope to help you. Q1: Two characteristic impedance formulas are often referred to: MicrostripZ={87 / [sqrt (Er +1.41)} ln [5.98H/ (0.8W+T)]W— The width of the lineT — The thickness of copper …
Printed circuit board design is based on circuit schematic diagram to realize the function required by circuit designer. PCB design mainly refers to layout design, which needs to consider the layout of external connection. When designing the PCB, it is important to note that each file should be connected as a whole at last, which …
Although semiconductor integration is becoming more and more high, many applications also have on-chip systems available at any time. And many powerful and open-box development boards can be easily obtained, but in many cases, the application of electronic products still need to use custom PCB. In one-time development, even a common PCB can play a …
When studying PCB design or working in PCB design, everyone will encounter various problems. In order to let everyone better solve these problems and avoid detours, here we share 6 common problems in PCB layout. 1. What Layout of the PCB Board Can Achieve The Best Heat Dissipation Effect? There are three main sources of …
PCB circuit board design software generally includes two major modules: schematic design and PCB design. The mainstream and powerful circuit board design software basically includes these two modules. The current mainstream circuit board design software are: Protel, PowerPCB, OrCAD, Viewlogic, ExpeditionPCB, Cadence PSD, MentorGraphices, ZukenCadStart, Winboard/Windraft/Ivex SPICE, PCBStudio, TANGO, PCBWizard (PCB production software package supporting …
Printed Circuit boards are the carrier to realize the functions of electronic circuits. As a circuit design engineer, I think you will meet many problems in the product design and development stage.The common problems are as: With the increase of electronic communication frequency, the requirements for PCB circuit accuracy are getting higher and higher. The …
