Everyone knows that making a PCB involves turning a well-designed schematic into a tangible PCB circuit board. Please do not underestimate this process; many things that work in theory can be difficult to achieve in practice, or some things that others can realize, others cannot. Thus, while making a PCB is not difficult, making a … Read more
Click the above “Mechanical and Electronic Engineering Technology” to follow us In the vast world of the electronics manufacturing industry, PCB (Printed Circuit Board) is undoubtedly the shining star. It is not only an indispensable component in electronic devices but also the bridge connecting various electronic components. However, during the production process of PCBs, engineers … Read more
The most basic purpose of PCB surface treatment is to ensure good solderability or electrical performance.Since copper in nature tends to exist in the form of oxides in the air, it is unlikely to remain as pure copper for a long time, so additional treatments are required for copper.There are now many PCB surface treatment … Read more
Use Hanghangcha for Industry Data 🕒 Welcome to explore the website: www.hanghangcha.com Printed Circuit Boards (PCBs) are known as the “mother of electronic products” and serve as a bridge that connects electronic components and circuits. They are printed boards that form connections between points according to a predetermined design on a common substrate. Their main … Read more
PCB (Printed Circuit Board) is the support body for electronic components. It is called a “printed” circuit board because it is made using electronic printing technology.Before the advent of PCBs, circuits were composed of point-to-point wiring. This solution had low reliability because as circuits aged, line breakages could lead to open or short circuits.As electronic … Read more
In the design and manufacturing process of PCB circuits, electronic components and devices play a crucial role. However, due to various influencing factors, some components are more prone to damage and failure than others. Do you know which components they are? The answer will be provided below. 1. Capacitors Capacitors are one of the common … Read more
01IntroductionTime flies. When I first started working, I found that I had a lot to say about the topic of PCB. Perhaps over the years, I have encountered many things related to PCBs. From initially disassembling circuits to designing my own boards, from foreign AD to domestic Lichuang EDA, from double-layer boards to four-layer and … Read more
