How to avoid EMC problems in PCB design

I have recently been asked about E MC- related issues, such as how to design to avoid EMC problems. I think that I always pay attention to the same shoes as Mr. Speed, and I will definitely ask this question. First of all, this is a systemic problem, not so good, especially for

What are the precautions for hand soldering PCBs?

For a PCB engineer, how to design the performance of a PCB, the parameters simulated by the software can not reflect anything. Only when the board is produced, soldered in person, and the actual performance is determined, can mass production be realized. Because in the actual production process, process and component soldering

Halogen-free PCB analysis, what is halogen-free PCB, why should we ban halogen?

Speaking of "halogen"! Presumably, the first reaction of readers is the fragrant roast chicken. However, today's Xiaobian and everyone to analyze is a halogen-free PCB! So what is a halogen-free PCB, why should I ban halogen? Please be patient and listen to Xiaobian! First, what is a halogen-free substrate Halogen-free substrate: According to the JPCA-ES-01-2003 standard: a

How to reduce RF effects in PCB interconnect design

The interconnection of the board system includes chip-to-board, interconnection within the PCB, and three types of interconnections between the PCB and external devices. In RF design, the electromagnetic properties at the interconnection point are one of the main problems facing engineering design. This article introduces the various techniques of the above

Six tips for PCB schematic production

Six things to consider when passing a PCB schematic to layout design. All the examples mentioned were developed using the Mul ti sim design environment, but the same concepts apply when using different EDA tools! Initial schematic transfer The device information, netlist, layout information, and initial trace width settings are also passed

Explore key steps to ensure successful PCB design

A printed circuit board (PCB) is the body of an electronic product, and the performance, life, and reliability of the final product depend on the electrical system it constitutes. Products that have high-quality circuits will have lower field failure rates and on-site return rates if properly designed. Therefore, the production cost of
