There are three main sources of heat in PCB: (1) heat generated by electronic components; (2) heat generated by the PCB itself; (3) heat transmitted from other parts. Among these three heat sources, the heat generated by components is the largest and is the main heat source, followed by the heat generated by the PCB…
In the PCB design process, once a PCB board has completed layout and routing, and the connectivity and spacing have been checked without error, is the PCB completed? The answer is of course no. Many beginners, including some experienced engineers, often rush through the process and ignore post-check due to time constraints, impatience or overconfidence….
New PCB board debugging method and experience summary For a newly designed circuit board, debugging often encounters some difficulties, especially when the board is relatively large and there are many components, it is often difficult to start. But if you master a set of reasonable debugging methods, debugging will be twice the result with half…
The horn of China’s comprehensive economic reform has been sounded. When almost all industries are facing active or passive reshuffles, the market competition and fighting are extremely fierce. How to return to low capital, take a new model of sustainable development, and accurately capture user groups with low prices and superior experience has become a…
PCB surface treatment generally includes tin spraying, OSP, immersion gold, etc. Here, “surface” refers to the connection points on the PCB that provide electrical connections between electronic components or other systems and the circuits of the PCB, such as pads or contact connections. Bare copper itself has good solderability, but it is easily oxidized and…
Explore the intricacies of bare PCB manufacturing in this comprehensive guide. From design to fabrication, delve into processes, materials, and industry standards that ensure high-quality printed circuit boards for various applications.
What software do you need to learn for circuit development and design? Circuit design software refers to software for circuit diagram drawing, optimization, testing, and simulation. In China, the most developed and used circuit design software are as follows: protel, powerpcb, Allegro, orcad, cam350, etc. These circuit design software include functions such as electrical schematic…
When developing electronic products with processors, how to improve anti-interference ability and electromagnetic compatibility? This article summarizes some methods for everyone. Selecting a microcontroller with a low external clock frequency can effectively reduce noise and improve the system’s anti-interference ability. For square waves and sine waves of the same frequency, the high-frequency components in the…
When starting a hardware development project, the original driving force will come from many aspects, such as market needs, needs based on the entire system architecture, functional implementation needs of the application software department, needs to improve certain aspects of the system, etc. Therefore, as a hardware system designer, you must take the initiative to…
Many electronics enthusiasts like to do some electronic production by themselves. When making, they often spend a lot of time on the circuit board. Most of them use universal boards, but universal boards can only be built with wires, and cannot be routed according to the PCB design they have designed. The things they make…
