There are many components on the circuit board. Their functions are different and have their own functions. They can complement each other to make the electronic product work normally or for a long time; let us talk about the role of the diode in it. The current flowing through the inductor coil in the circuit [...]
On May 19, 2020, in Munich, Germany and Boca Raton, Florida (GLOBE NEWSWIRE), HENSOLDT, a sensor solution provider, and Nano Dimension, a leading supplier of 3D printed electronics (AME)/printed electronics (PE), are using 3D Significant breakthroughs have been made in the development of high-performance electronic components in printing technology. Using Nano Dimension’s newly developed dielectric [...]
The circuit connection of the multi-layer board is through the buried hole and blind hole technology. Most motherboards and display cards use 4-layer PCB boards, and some use 6, 8-layer or even 10-layer PCB boards. To see how many layers there are on the PCB, it can be identified by observing the via holes, because [...]
FPC is a kind of printed circuit board, which is called flexible circuit board, and we call it FPC soft board. FPC generally uses PI as the base material, which can be bent and flexed arbitrarily. PCB is a so-called rigid circuit board, which is usually called a hard board. PCB generally uses FR4 as [...]
The names of the circuit boards are: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra Thin circuit boards, printed (copper etching technology) circuit boards, etc. The circuit board makes the circuit miniaturized [...]
How to set the speed and temperature of reflow soldering just right The main factors that determine the quality of reflow soldering products are the settings of reflow soldering temperature and reflow soldering speed in the reflow soldering process. These two key process points are set... How can I disassemble the IC block During circuit [...]
1. Principle of 20H If the printed circuit board has the ideal voltage and frequency, it will transmit electromagnetic into space; In order to reduce the probability of this situation, it is necessary to make the physical size of the signal line printed board of one floor and the physical size of the surrounding connection [...]
Automatic soldering machine for PCB circuit board Automatic solder robot is a solder welding equipment, so in addition to the manipulator movement function, its main or to complete the solder job. So the core part of the soldering robot is the welding system. The solder system mainly consists of automatic tin feeding mechanism, temperature control, [...]
PCB is an important electronic component, the support body of electronic components, and the carrier of electrical connection of electronic components. What are the requirements for PCB component layout? Let's introduce it to you. 1, the signal Signal interference is the most important factor to consider in PCB layout design. The most basic aspects are: [...]
Detailed knowledge of double sided circuit board welding. Compared with the single panel, the double-sided circuit board has higher wiring density and smaller aperture. The metallized holes on which interlayer interconnection depends are directly related to the reliability of printed circuit boards. With the narrowing of the aperture, some sundries, such as grinding debris, volcanic [...]
