The AMC23C12 is an isolated window comparator with a short response time. The open-drain output is separated from the input circuitry by an isolation barrier that is highly resistant to magnetic interference. This barrier is certified to provide reinforced galvanic isolation of up to 5 kVRMS according to VDE V 0884-11 and UL1577, and supports [...]
1、 Solder paste stage 1.1 solder paste Solder paste (or solder paste) is the key material for welding. As Wikipedia, it is a kind of material used in the manufacturing of printed circuit boards to connect surface mount components to pads on the board The paste is initially sticky. After heating, it is pasted on [...]
Whether it is for personal use or commercial applications, the defects of flexible circuit boards will cause serious adverse consequences. So, how to quickly detect the fault of flexible circuit board? 1. Determine fault location Once there are signs of problems, the next step is to track and determine the location until the defect is [...]
market? About the future, whiPrinted circuit board (PCB) is known as the "mother of electronic products". It can realize the interconnection between electronic components and play the role of relay transmission. It is the support of electronic components. According to the survey of Yidu data, the global PCB output value in 2021 was about US [...]

Impedance matching is a part of microwave electronics. It is mainly used in transmission lines to achieve the purpose that all high-frequency microwave signals can be transmitted to the load point, and no signal will be reflected back to the source point, so as to improve energy efficiency. In general, there are two kinds of [...]
In the process of research and development or learning, you often need to buy a small number of films. At this time, you can only find goods in the electronic market. The goods in the market are mixed. You should learn to distinguish between good and bad. Here are some problems faced by IC spot: [...]
Brief description of QFN package QFN (quad flat no leads package) is a pin free package, which is square or rectangular. There is a large area of exposed pad in the center of the bottom of the package for heat conduction, and there are conductive pads for electrical connection around the package periphery of the [...]
