The basic principles of high-speed PCB layout are as follows: ① Considering the distribution parameters of circuit components under high-frequency working conditions, all components should be arranged evenly, neatly and compactly on the double-sided circuit board, so as to minimize and shorten the lead length between components. ② Analog circuits should be separated from digital […]

1. Overview of embedded hardware circuit design With the development of Internet of Things and artificial intelligence technology, our life is becoming more and more intelligent and informative. Smart phones, smart bracelets, smart locks, smart refrigerators, autonomous driving, robots and other smart products are emerging one after another, and human beings are about to enter […]

There are too many PCB manufacturers, and some larger ones will choose customers. For example, your factory is small and the order quantity is not enough, so they may not cooperate with you. Some small factories may have the technology, but by the time of mass production, they may not be able to meet your […]

The topic of intelligent vehicle development continues to be hot, especially after the green transportation boom of all-electric EV vehicles, and the demand for electronic design, such as autonomous driving, networked vehicles, and active/passive vehicle safety, is stimulated. Not only is the development of new technologies maturing, but the demand for automotive electronic PCB required […]

The layout of PCB Layout design is described from three aspects: right-angle layout, differential layout and serpentine: I. Layout design right-angle routing (three aspects) The influence of right-angle routing on the signal is mainly reflected in three aspects: first, the corner can be equivalent to the capacitive load on the transmission line, slowing down the […]

Circuit board simulation is no longer an option but an inevitable way for most layout designs today. EDA industry is the key factor to promote the rapid development of the global electronic industry, and its market size is as high as $1 trillion. Most of the sales are monopolized by several big companies (measured by […]

Drilling jig is one of them, but 90% of the jigs have been wave welded. This kind of jig is made of hard computer gongs, and some can move the twist drilling equipment or other drilling devices to the position of each hole accurately by moving the mold. A typical practice is to leave a […]

When it comes to outsourcing, the first thing that people think of is to send products or parts that they can’t or don’t want to produce to other factories for OEM. In fact, driven by the increasingly fine social division of labor, modern outsourcing is not only the outsourcing of products, but also the initial […]

1.layout design PCB wiring and layout isolation criteria: strong and weak current isolation, large and small voltage isolation, high and low frequency isolation, input and output isolation, and the demarcation standard is one order of magnitude difference. The isolation method includes: the space is far away and the ground wire is separated. 2. The crystal […]

In PCB design, whether to use SMD magnetic beads or SMD inductors mainly focuses on the application scenario. Design pcb The design of printed circuit board is based on the circuit schematic diagram to realize the functions required by circuit designers. The design of printed circuit board mainly refers to layout design, and the layout […]
