In order to reduce crosstalk between lines, the line spacing should be large enough. When the line center spacing is not less than 3 times the line width, 70% of the electric fields can be kept from interfering with each other, which is called the 3W rule. If you want

As an electronic person, the basic knowledge of digital circuits is something that everyone must master, and the same is true for electronic people who learn PCB design. Today, 2PCB mainly introduces the combinational logic circuits in digital circuits. About combinational logic circuits The circuit that uses digital signals to

In all the processes of PCB design, wiring is the most delicate, most restrictive, and most time-consuming. Many engineers spend their daily work “drawing wires” diligently. Next, 2PCB will share some very practical wiring tips with you, hoping to be helpful to you. Wiring tips between power and ground wires

Layout means placing the components on the board reasonably based on comprehensive consideration of signal quality, EMC, thermal design, DFM, DFT, structure, safety regulations and other requirements. In high-speed PCB design, reasonable layout is the first step to successful PCB design. Next, 2PCB will introduce the ideas and principles of

Signal integrity (SI) refers to the quality of the signal on the transmission path. With the increase in the output switching speed of integrated circuits and the increase in the density of PCB boards, signal integrity has become one of the issues that must be concerned about in high-speed digital

Optocoupler (OC) is also called photoelectric coupler, abbreviated as OC. It is a device that uses light as a medium to transmit electrical signals. Usually, the light emitter (infrared light-emitting diode LED) and the light receiver (photosensitive semiconductor tube) are encapsulated in the same tube shell. When an electrical signal

At present, high-speed PCB design is widely used in the fields of communication, electronics, computers, graphics and image processing, etc. All high-tech value-added electronic product designs are pursuing miniaturization, lightweight, low power consumption, low electromagnetic radiation, high reliability and other characteristics. In order to achieve the above goals, engineers need

#2PCBTechnology held a tug-of-war competition on the Dragon Boat Festival. Everyone strives to do their best for the success of the team, just as hashtag #2PCB strives to do our best for the success of our customers.

As the saying goes, “The master leads you to the door, and the practice depends on yourself.” For PCB design beginners, it is easy to “have no direction, don’t know where to start, and be confused.” Therefore, if you can get some guidance and suggestions from masters, you will definitely

As a qualified PCB design engineer, you need to master the knowledge of design software, electronic components, key signals, boards, SI, PI, EMC, etc. Today, 2PCB will briefly introduce the selection of PCB boards. How to choose PCB boards? The selection of PCB boards must strike a balance between meeting

PCB design is a very important part of electronic product design, and it is an important carrier of electronic products. A good PCB should not only look good, but also meet the requirements of high cost performance, good electrical performance, high stability and reliability, easy production and maintenance, and easy

The processing of the power plane plays a very important role in PCB design. In a complete design project, the processing of the power supply can usually determine the success rate of the project by 30%~50%. Today, 2PCB will introduce the 3 basic factors that should be considered in the
