With the rise of Internet of Things technology, it is more and more common for electronic products to be equipped with wireless communication function, and wireless communication technology is realized by radio frequency circuit on PCB. Unfortunately, even the best PCB designers are often discouraged from radio frequency circuit, because it will bring great design […]

The design of schematic diagram is the basis of circuit design. Only on the basis of designing schematic diagram can the circuit simulation of printed circuit board be carried out. The following briefly introduces the design steps of circuit schematic drawing by new scholars of Protel DXP2004SP2. It contains the following nine specific design steps: […]

Why should test points be added to circuit board design? Circuit board design plus test points are not needed in PCB production, but ICT test after PCBA is completed, which is to test whether there is any problem in circuit board welding and whether the performance meets the requirements. In the production of PCB, the […]

The design of single-sided PCB requires a lot of professional data and some physical knowledge, which can be said to be a comprehensive skill project. If you want to make a high-quality PCB, you need not only a solid foundation, but also sensitivity to impedance. The impedance involved in PCB mainly includes the following aspects: […]

The first and fourth layer PCB design drawing program: 1. Draw a circuit diagram and make a netlist. Among them, the process of drawing schematic diagram involves drawing elements and packaging, so it is no problem to master these two kinds of schematic diagrams. The elimination of errors and warnings can solve general problems. You […]

High-speed PCB design is a relatively complicated process. Because of the need to fully consider many technical factors such as signal, impedance, transmission line, etc. in high-speed PCB design, it often becomes a major difficulty for beginners in PCB design. The basic concepts and technical points of high-speed PCB design provided in this paper will […]

I believe everyone knows the working principle of the circuit board design: the insulating material of the substrate is used to isolate the conductive layer of the copper foil on the surface, so that the current can wander in various components along the route designed in advance, thus realizing functions such as doing work, amplifying, […]

Organization is the key to design efficiency, and the lack of organization will reduce the efficiency of PCB design. Take design rules as an example: when starting a new project, many PCB design engineers tend to redesign their designs according to their own design rules, instead of relying on an appropriate, organized and systematic rule […]
