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, […]

Flexible printed circuit (FPC) is a kind of high reliability and excellent flexible printed circuit board made of polyimide or polyester film. It has the characteristics of high wiring density, light weight, thin thickness and good flexibility. Today, Xiaobian will introduce you to four common flexible printed circuit board. 1. Single-sided flexible board Lowest cost. […]

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 […]

There are many ways to solve EMI problems. Modern EMI suppression methods include: using EMI suppression coating, selecting appropriate EMI suppression parts and components, EMI simulation design, etc. Starting from the most basic PCB layout, this paper discusses the function and design skills of PCB layered stacking in controlling EMI radiation. Power bus If a […]
