The copper wire of PCB falls off (also known as copper throwing), and PCB factories all say that it is the problem of laminate, which requires its production factory to bear the bad losses. According to customer complaint handling experience, there are several common reasons for copper rejection in PCB factory: I. Process Factors of […]

PCB design is to use EDA tools such as Allegro, PADS, Mentor, AD, etc. according to the circuit schematic diagram for layout and wiring, so as to realize the function of hardware circuit. Excellent PCB design engineers should not only be proficient in EDA software, but also know the circuit principle, SIPIEMC knowledge, have a […]

As far as the current development status and trend of international electronic circuits are concerned, the development prospect of PCB is very broad, but we will inevitably encounter some mistakes in the process of PCB design. This article will show you the development prospect of PCB and some common mistakes. Will you make these mistakes? […]

The design of a PCB circuit board mainly includes defining product requirements, designing PCB hardware system, device selection, PCB drawing, PCB production proofing, welding debugging and other steps. So what are the points to pay attention to in these steps? Xiaobian takes you fine, be sure to be fine! First, clear demand At the beginning […]

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 […]

1. print PCB circuit board. Print the drawn circuit board with transfer paper, and pay attention to the slippery side facing yourself. Generally, two circuit boards are printed, that is, two circuit boards are printed on a piece of paper. Among them, the printed circuit board with the best printing effect is selected. 2. Cut […]
