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, […]

Generally, the design current of PCB will not exceed 10A or even 5A. Especially in household and consumer electronics, the continuous working current on PCB usually does not exceed 2A. Recently, however, the company’s products should be designed with a power line, and the continuous current can reach about 80A. Considering the instantaneous current and […]

A good PCB layout design can optimize the efficiency, slow down the thermal stress, and minimize the noise and interaction between traces and components. All this comes from the designer’s understanding of the current conduction path and signal flow in the power supply. When a prototype power panel is powered on for the first time, […]

Printed circuit boards can be used in all fields, including motion control applications. The new CAD software can help designers create better schematic diagrams and layouts. Gone are the days when “electricity” and “mechanics” became independent disciplines. Nowadays, almost all mechanical systems are equipped with some form of electronic equipment for monitoring, control or both. […]

Cleaner production refers to continuously adopting measures such as improving design, using clean energy and raw materials, adopting advanced technology and equipment, improving management and comprehensive utilization, etc., to reduce pollution from the source, improve resource utilization rate, and reduce or avoid the generation and discharge of pollutants in the process of PCB production, service […]

R5 in PCB refers to the resistance. There are many resistors in the circuit diagram, which are listed in sequence, R1, R2? … (the previous “R” refers to the resistance in general; The Arabic numerals at the back are components; Here is the sequence number of the resistor. There will be a lot of component […]
