Here you'll find insights into PCB design, tech trends, assembly issues, and trending topics
in the general news media as they relate to printed circuit board technology.
As experts in the manufacture and assembly of printed circuit boards, we work to make our blog a helpful resource on PCB topics and the industries that we work with, including automotive, consumer electronics, aerospace and many more.
Each PCB is basically composed of an aperture hole layer, a DRILL layer, a circuit layer, a solder mask layer, and a character layer. In CAM350, each layer loaded is distinguished by a different color, so that we can easily operating.
EI: Electromagnetic interference, is widely found in various types of electrical and electronic equipment. Various types of electrical and electronic equipment emit electromagnetic waves more or less when they work. This kind of electromagnetic waves will interfere with the normal operation of the entire equipment. Due to inadequate consideration of electromagnetic compatibility in the design of electronic products, some electrical and electronic products have failed. Therefore, the author summarizes some points to pay attention to.
Six common shortcuts in PADS software
PCB routing is a key element of ESD protection. A reasonable PCB design can reduce the unnecessary costs of troubleshooting and rework. In the PCB design, due to the use of transient voltage suppressor (TVS) diodes to suppress direct charge injection due to ESD discharge, it is more important in the PCB design to overcome electromagnetic interference (EMI) electromagnetic field effects generated by the discharge current. This article will provide PCB design guidelines that can optimize ESD protection.

All of the examples in this article were developed using the multisim design environment, but the same concepts apply even with different eda tools.
Four principles as below:
People think that the earth can absorb all the charges, always maintain a stable, is the ultimate reference point. Although some boards are not connected to the earth, but the power plant is connected to the earth, the power of the board will eventually return to the power plant into the ground.

7 types of PCB working layer:
For reasons of cost, single or double printed circuit boards are used in common consumer equipment. With the widespread use of digital pulse circuits, single-layer and double-layer electromagnetic compatibility issues become more and more prominent.
PCB Best Design Methodology: Six things to consider when passing a PCB schematic to a layout design. All examples mentioned in this article were developed using the Multisim design environment, but the same concepts apply when using different EDA tools.
This is a big problem. We set aside other factors, just the PCB design aspects, share the following experience for reference exchange:
At the moment, users most need a tool that combines timing analysis and SI, and the interface is optimized for easy setup and includes Design KIT.
At present, there are many kinds of EMC simulation softwares in the world.
