Here you'll find insights into PCB design, tech trends, assembly issues, and trending topics
in the general news media as they relate to printed circuit board technology.
As experts in the manufacture and assembly of printed circuit boards, we work to make our blog a helpful resource on PCB topics and the industries that we work with, including automotive, consumer electronics, aerospace and many more.
For a beginner, choosing an FPGA suitable for learning is the only way for the entire FPGA learning career. This article will introduce the principles that should be grasped when choosing FPGA.
This article is the following article "Summary of RF PCB Layout and Louting", mainly describes the skills and methods of high-frequency PCB design, electromagnetic compatibility design, and the use of differential signal line routing strategy in the circuit board design process.
Radiofrequency (RF) circuit board design is often described as a kind of "black art" because there are still many theoretical uncertainties, but this view is only partially correct. RF circuit board design also has many guidelines that can be followed and should not be Ignored by law.
General Principles of PCB Layout and Wiring in AD
As an electronic engineer, the miniaturization of electronic products and the complexity of system design make PCB design more and more complicated. Nowadays, highly integrated circuit boards are getting smaller and smaller, and the pins of packaged devices are getting denser and denser, all of which put tremendous pressure on wiring.
In order to reduce crosstalk between lines in PCB design, the 3W principle should ensure that the line spacing is large enough. When the line center spacing is not less than 3 times the line width, most of the electric fields can be kept from interfering with each other. This is the 3W rule. The 3W principle means that when multiple high-speed signal lines are routed over a long distance, the spacing should follow the 3W principle. For example, clock lines, differential lines, video and audio signal lines, reset signal lines and other system key circuits need to follow the 3W principle. Not all wiring on the board is mandatory to comply with the 3W principle. Satisfying the 3W principle can reduce the crosstalk between signals by 70%, while meeting 10W can reduce the crosstalk between signals by nearly 98%. Although the 3W principle is easy to remember, it should be emphasized that there are previous conditions for the establishment of this principle.
For the new PCB copy board that has just been taken back, we must first roughly observe whether there are problems on the board, such as whether there are obvious cracks, whether there are short circuits, open circuits, etc. If necessary, check whether the resistance between the power supply and the ground wire is large enough.
Regarding the knowledge of chip decryption, we know from the surface that it has the meaning of chip and decryption. If we want to understand chip decryption more deeply, we must start from these two points. The following is to explain to everyone around the chip.
With the rapid development of electronic products, a large number of highly integrated devices such as BGA, QFP, PGA and CSP are used in PCB production, and the complexity of PCB has also increased greatly. The subsequent PCB design and manufacture are difficult, testing and soldering are difficult. Production problems such as defects, mismatched components, and difficult maintenance.
Recently, I came into contact with a DFM software for PCB boards, which made me a little excited. I wrote an article specifically because I know that it can save me a lot of labor and improve work efficiency in the future.
The "Super Factory" for the production of curved screens and folding screens-Tianma's sixth-generation flexible AMOLED project main plant in Xiamen Torch High-tech Zone was successfully capped yesterday, which was one month earlier than the original plan, refreshing the construction of panel plants of the same industry and the same scale speed.
NI acquires monoDrive to accelerate the development of autonomous vehicles. On May 4, NI announced the completion of the acquisition of monoDrive, a company headquartered in Austin, Texas, USA. This acquisition expanded N.
It is necessary to examine MIL-PRF-50884, MIL-PRF-31031, as well as MIL-PRF-55110 criteria to make sure that the PCBs that are being produced autumn in line with the specifications.
By investigating the data of power battery supporting industry of new energy vehicles in 2019, this paper studies the bottleneck of battery technology in the development of new energy vehicles summarizes and analyzes the root causes of vehicle safety accidents, and then from the aspects of battery system R & D and design, cell production and manufacturing, production quality control, etc, The technical requirements and management requirements for safety protection of power battery system are put forward.
As an engineer who has been engaged in PCB design for many years, he often feels troubles during long-time drawing board work. It is not due to the design requirements of the board, nor is it limited by the compatibility between different product structures, but an inability to Ignored problem-PCB DFM.
This page is about EMC design knowledge in PCB circuits for engineers.
Most of the students majoring in electronic engineering need to try to make simple electronic circuit DIY projects and make PCBs. This article will introduce "how to make PCB at home" without any special materials. Let’s briefly review the content of the previous article.
This article introduces the ranking of the world's top printed circuit board manufacturers released by NTI in 2019, and understands the scale of global and Chinese printed circuit companies. China's PCB manufacturing industry has a higher proportion of the world and has a bright future.
There is no doubt that the industrial robots of the future will replace people to do a lot of work. Understanding the design process and software of robots will become the basic knowledge for more and more engineers.
PCB industry is technology intensive and capital intensive, but it is still labor-intensive. With the improvement of robot performance and the decline of price, "automation equipment + industrial robot operation" will replace the traditional "automation equipment + manual operation" production mode, which will become the transformation and development trend of PCB industry.
