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

In PCB design, the handling of power and ground wires deserves engineers’ attention. Because even if the wiring in the entire PCB board is completed well, interference caused by insufficient consideration of power and ground wires will degrade the performance of the product and sometimes even affect the success rate

For human, we will get sick if the body temperature is too high. For electronics, the components will fail due to overheating and the reliability will decrease. Therefore, it is very important to handle the heat dissipation of the circuit board well. In thermal design, the heat sources mainly come

How can I learn PCB design well? Although this problem is a commonplace, for many PCB design beginners, it is an urgent problem that they need to solve. Because efforts without direction are often in vain and meaningless. In this article, 2PCB has collected some suggestions from technical experts in

Everyone has their own little habits, whether in life or work. Sometimes, some small habits are harmless, but some bad habits need to be eliminated. As a hardware engineer, you must get rid of the following bad habits~ 7 Bad Habits Hardware Engineers Need to Break 1. The PCB design

Metal-Oxide-Semiconductor Field-Effect Transistor, referred to as MOSFET, is a field-effect transistor that can be widely used in analog circuits and digital circuits. ). In power supply design, MOSFET is often the most overlooked electronic component by engineers. MOSFET is an essential electronic component in power supply design. Most engineers’ use
