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.
In PCB design, some holes seem insignificant, but without these "tool holes", the board will not achieve the expected function or even be manufactured correctly.
In the design of the PCB board, the anti-ESD design of the PCB can be achieved through layering, proper layout, and installation.
Layout considerations
By comprehending the sorts of non-standard type variables that you might be hired to make, you can utilize the required standards to sustain your agreement supplier (CENTIMETERS) as well as lessen any type of turn-around hold-ups or added prices.
High-speed issues including timing and signal integrity (SI) are currently the central issue for digital PCB board designers. All PCB designs will become high-speed designs.
How to Select the Ideal Trace Size for PCB design? For everybody that develops a PCB, eventually, they are confronted with the choice of specifying trace size.
In the introduction of this chapter and the previous chapters, we have emphasized some principles that need to be followed in PCB design. Here we will summarize these principles for readers to test during the design, or as an inspection after the design is completed. The basis for reference.
The above are the general principles of PCB board layout and wiring, but in actual operation, the layout and wiring of components is still a very flexible job.
Layout is one of the most basic job skills for PCB design engineers. The quality of the wiring will directly affect the performance of the entire system. Most high-speed design theories are finally realized and verified through Layout. It can be seen that wiring is crucial in high-speed PCB design.
When designing the PCB board, the most consideration for our wiring is how to connect each layer to the network signal line in the most reasonable way. The denser the high-speed PCB board circuit, the greater the density of vias (VIA) is placed, and the vias can serve each layer. The role of electrical connection between.
this page talk about the distance and related safety requirements about PCB design.
Standardize the PCB process design of the product, stipulate the relevant parameters of the PCB process design, so that the PCB design meets the technical specifications of manufacturability, testability, safety, EMC, EMI, etc., and build the product process, Technology, quality, and cost advantages.
In order to make the designed products work better and effectively, the PCB design takes into account its anti-interference ability, the relationship with the specific circuit, and the reduction.
The purpose of the prompt is to help the quality and improve the quality of the PCB design.
When we PCB design aspects, often discover that when components count as well close will certainly turn green, remove will certainly be recovered.
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.
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.
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.
