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 …
–The difference of gross profit rate between large and small batch board manufacturers is obvious Printed circuit board is the key electronic interconnection component of electronic products. It’s known as the “mother of electronic products”. The downstream of printed circuit board is widely distributed, covering communication equipment, computer and its surrounding, consumer electronics, industrial control, …
For people who study electronics, it is natural to set up test points on the circuit board. But for people studying machinery, they might ask what are the test points. Maybe I’m still a little confused. I remember that when I first worked as a process engineer in a PCBA processing plant, I asked many …
We all know that the heat generated during the operation of electronic equipment causes the internal temperature of the equipment to rise rapidly. If the heat is not dissipated in time, the equipment will continue to heat up, the device will fail due to overheating, and the reliability of electronic equipment will decline. Therefore, it …

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 …
