We often need to quickly estimate the resistance of an alignment or plane on a printed circuit board rather than perform tedious calculations. Although there are now available
How to design a PCB board is not easy. Other engineers have spent some time learning the rope
HDI stands for High Density Interconnect. HDI PCBs are defined as boards with a higher density of wiring per unit area
Eight, ESD suppression for PCB design PCB routing is a critical element of ESD protection, and proper PCB design can reduce unnecessary costs associated with failure checking and rework. With the use of transient voltage suppressor (TVS) diodes to suppress direct charge injection due to ESD discharge, PCB design is more important to overcome electromagnetic …

Multi-layer PCBs are generally defined as high multilayer PCBs with 10 – 20 layers or more, which are more difficult to process than traditional multilayer PCBs and their quality and reliability requirements are high, mainly used in communication equipment, high-end servers, medical electronics, aviation, industrial control, military and other fields. In recent years, the market …
First of all, PCBs, as printed circuit boards, primarily provide the interconnection between electronic components. Color is not directly related to performance, and differences in pigmentation do not affect electrical properties. the performance of a PCB is determined by the materials used (high Q), wiring design, and several layers of the board. However, in the …

01, What is the 20H principle? The 20H principle refers to the 20H distance of the power layer relative to the ground layer inward, with H indicating the distance between the power layer and the ground layer. And of course to suppress the edge radiation effect. At the edge of the board will radiate electromagnetic …
PCB design encountered the five major problems, so simple and effective solution Read More »
High density interconnect PCBs are a way to leave more space on a printed circuit board to increase efficiency and speed up transfer speeds. It’s relatively easy for most aggressive companies using printed circuit boards to understand how this will benefit them. High Density Interconnect HDI PCBs represent one of the fastest growing segments of the …
This article lists a variety of different design oversights, explores the causes of circuit failure for each, and gives suggestions on how to avoid these design flaws. This article uses a double layer PCB with FR-4 dielectric, 0.0625in thickness, and a grounded bottom layer of the board as an example. The operating frequency is in …

With the addition of PCB alignment express, EMC design is something we electronic engineers have to consider. When faced with a design, there are 5 important attributes to consider when performing an EMC analysis of a product and design: (1) Critical device size: the physical size of the emitting device that produces the radiation. …
