As PCB high-speed signal design becomes more and more common, the design of electronic circuits faces more and more challenges such as signal integrity, power integrity, heat, and electromagnetic compatibility. Introducing simulation verification methods in design will greatly improve product development efficiency, design correctness, and achieve the fastest product launch to market. MentorGraphic’s HyperLynx software…

Practical experience and skills of PCB package drawings of electronic devices How to design PCB package drawings of electronic devices? What practical experience and skills are there? I often ask myself this question. As an electronics fan who has worked for more than 10 years and has drawn at least hundreds of PCB boards, I…

The difference between two-layer boards and four-layer boards in PCB printed circuit boards PCB printed circuit boards are one of the most important components of electronic products and are the carriers for connecting electronic components. The design and manufacture of PCB printed circuit boards determine the performance and reliability of electronic products. In the manufacture…

With the development of electronic communication technology, wireless radio frequency circuit technology is more and more widely used. The performance index of radio frequency circuit directly affects the quality of the whole product. The anti-interference design of radio frequency printed circuit board (PCB) is of great significance to reduce the electromagnetic information radiation of the…

Every engineer has a “worst case scenario” story that they’ve survived. During the worst week of my career, we received a shipment of expired PCBs. These hardware had been installed in customer computers a month prior. We were a bit mortified. Needless to say, these new boards were shipped in a bit of a rush….

One of the major trends in electronic design is the use of open source hardware and its accompanying open source schematics and PCB layouts. Growth Trend Challenges and advantages The integration of open source design faces several challenges, such as more noise problems. When the circuit board uses high-current switches, noise will scatter to other…

Copper plating in PCB design is a very important part of circuit board design. What is copper plating in PCB? It is to fill the idle space in the non-wiring area on the PCB with solid copper. The significance of copper plating is to reduce the ground impedance and improve the anti-interference ability; reduce the…

It’s no secret that designers are squeezing more performance out of printed circuit boards. Power densities are rising, and with them come higher temperatures that can wreak havoc on conductors and dielectrics. Increased temperatures – whether from I2R losses or environmental factors – affect thermal and electrical impedance, leading to erratic system performance, if not…

PCB boards are called printed circuit boards in Chinese, also known as printed circuit boards and printed circuit boards. They are important electronic components. The quality of PCBs largely determines the quality of electronic components. Therefore, in the process of producing PCB boards, detection is a very important part. Through detection, defects that affect functionality,…
