Nowadays, the trend of increasingly compact electronic products requires three-dimensional design of multilayer printed circuit boards. However, layer stacking raises new problems related to this design viewpoint. One of the problems is to obtain high-quality stack construction for the project. With the production of more and more complex printed circuits composed of multiple layers, the […]

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 […]

If some preventive measures are not taken in pcb design, interference, data loss and poor signal integrity may occur. We will outline many rules and guidelines to consider when choosing Bluetooth technology for a given application, more specifically, designing it into the circuit board. A variety of applications use Bluetooth, including: Beacons used in shopping […]

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 […]

When many people get to know the battery circuit board initially, they will be scared by the various layers of the circuit board. Each layer has its own name and function, with strict division of labor and complicated contents. Let’s give you a systematic introduction today! 1. Mechanical mechanical layer As the name implies, the […]

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, […]
