Speaking of flexible circuit boards, many friends are very unfamiliar. I do n’t know what this is. The flexible circuit board is also called FPC circuit board. It is a technology that has only been developed in recent years, mainly used in some sophisticated In products, mobile phones, computers, digital cameras, flexible circuit boards are [...]
Flexible circuit board Flexible circuit boards are also called flexible circuit boards and flexible circuit boards. Referred to as flexible board or FPC, it is made of a flexible insulating substrate. Compared with ordinary hard resin circuit boards, flexible circuit boards have the advantages of high wiring density, light weight, thin thickness, less wiring space [...]
EV dedicated units require higher reliability, miniaturization, and low loss. ROHM can provide solutions in the form of solutions, which can provide power components represented by SiC and IGBT, as well as gate driver ICs that drive these devices. In addition, there are many general-purpose products such as power ICs, transistors, diodes, and current-shunt resistors [...]
The abbreviation of Flexible Printed Circuit is FPC, also known as flexible circuit board, flexible circuit board, flexible circuit board, flexible printed circuit board, flexible circuit board, referred to as flexible board or FPC, has high wiring density, good flexibility, It can be bent, light weight and thin. Mainly used in many products such as [...]
As a PCB design engineer, it is necessary to have certain high-speed knowledge. In terms of signals, high-speed signals usually appear in various parallel buses and serial buses. Only when we know what is the bus can we know its running speed and start wiring. bus A bus is a shared physical path for communication [...]
This structure is suitable for such high-power occasions. In fact, I have been exposed to this topology since I studied the design of switching power supplies. I have made several high-power power supplies using this structure. The performance is excellent. This kind of structure has a special liking, that is, the structure is simple and [...]
Superconductors are also called superconducting materials. It generally refers to a conductor whose resistance is zero at a certain temperature. In the experiment, if the measured value of the conductor resistance is lower than 10 to the -25th power Ω, the resistance can be regarded as zero. Superconductors not only have the characteristics of zero [...]
Today, with the rapid development of science and technology, the replacement of electronic products is getting faster and faster, and the technology of LED lights is also constantly developing, which is colorfully decorated for our cities. LED devices account for about 40% to 70% of the cost of LED display screens, and the significant reduction [...]
After continuous development of the optical lens industry, a complete industrial chain has been formed. The optical lens is at the core of the optical component industry chain. The industrial chain includes upstream optical lens raw materials (optical glass, optical plastics). The midstream optical components are mainly the manufacture of optical components such as spherical [...]
Today we will study the different effects of capacitors on direct current and alternating current. The two circuits, the small bulb and the capacitor are exactly the same, and the effective value of the DC voltage and the AC voltage are equal. When the switch is closed, the small light bulb in the DC circuit [...]
