In product development, from the perspective of cost, schedule, quality and performance, it is usually best to carefully consider and implement the correct PCB design as early as possible in the project development cycle. Add-ons and other “quick” patches implemented later in the project are usually not ideal solutions in function, their quality and reliability […]

Printed Circuit Board (PCB) is an indispensable element in almost all electronic applications. They bring life to electronic and electromechanical devices by routing signals in circuits and realizing their functions. Many people know what PCBs are, but only a few people know how they are made. Nowadays, PCB is constructed by pattern electroplating process. They […]

In Xi ‘an PCB design proofing, the concepts of analog ground/digital ground and analog power supply/digital power supply are often mentioned by engineers. In fact, these concepts are only relative, and the premise of their existence is that the interference of digital circuits to analog circuits has reached a certain level. According to Xiaobian, there […]

When talking about printed circuit boards, novices often confuse “PCB schematic diagram” with “PCB design document”, but in fact they refer to different things. Understanding the differences between them is the key to successful PCB manufacturing, so in order for beginners to do this better, this paper will break down the key differences between PCB […]

In PCB proofing, rational and effective use of components is an important guarantee for the stability of PCB performance and quality. So, what problems should be paid attention to when using components in PCB proofing process? 1. PCB proofing limits the output current to avoid locking effect of CMOS circuit; Lock-in effect means that there […]

MCU is just the beginning … The cost and time-to-market requirements of entry-level MCU design are becoming more and more urgent. With the development of embedded software becoming the biggest contributor, MCU development kit must provide the same high-level value and usability as MCU. At present, designers demand powerful, simple, low-cost or, in some cases, […]

It is said that 5G will change everything, among which 5G medical health is an important application field of 5G technology in medical health industry. With the arrival of the official commercial use of 5G and the full integration and application of cutting-edge technologies such as big data, internet plus, artificial intelligence and blockchain, 5G […]

[…]

CadenceAllegro is now almost the actual industry standard in high-speed board design. The latest version is Allegro16.5 released in May 2011. Combined with its front-end product Capture, it can complete high-speed, high-density and multi-layer complex PCB design and wiring. Allegro has the advantages of easy operation, friendly interface and powerful functions (such as simulation, signal […]

The thermal, mechanical and electrical behavior of each PCB depends on the material characteristics of PCB substrate, conductor and component materials. Among these different materials, PCB designers can control the behavior of the board to the greatest extent by choosing the right PCB substrate material. The performance of PCB materials, especially the performance of resins […]
