Modulation is the process of processing the encoded information of a signal source to make it suitable for transmission. Generally speaking, this means converting the baseband signal (source) into a band communication signal with a very high frequency relative to the baseband frequency. This band communication signal is called a modulated signal, while the baseband [...]
Communication equipment Communication equipment, 76 companies, with a total market value of 750 billion, PE57. This index has been relatively weak in recent years, with a peak of 6500 in 2015 and a drop below 2000 at the end of 2018. Three times in these years, the peak has stopped at 3800. In February of [...]
Smart city, 5G Internet of Things, virtual reality... These attractive future landscapes are drawn by chips and circuit boards. The microelectronics industry, represented by integrated circuits, is the core of high-tech industry, the key technology for informatization to drive industrialization, accelerate the optimization and upgrading of traditional industrial structure, and the cornerstone of the development [...]
Flexible circuit board is a kind of pcb circuit board, also known as soft board and flexible printed circuit board. It is mainly made of flexible substrate and has high reliability and flexibility. It has the characteristics of thin thickness, flexible, high wiring density, light weight and high flexibility. It is mainly used in mobile [...]
The resonant circuit board of ultrasonic transducer is an independent drive circuit with impedance and resonant frequency, including DC power supply, switching components, voltage divider capacitor components, transformer, resonant inductor, etc., which can effectively ensure that the ultrasonic cleaning transducer can not be damaged due to voltage, the maximum output voltage is controllable, and the [...]
PCB (Printed Circuit Board), also known as printed circuit board (PCB) in Chinese, is an important electronic component, mainly composed of insulating substrate and conductor materials, and plays a supporting and interconnection role in electronic equipment. The main advantage of using circuit board is to greatly reduce wiring and assembly errors, and improve the automation [...]
Finally, it was a great experience, and the most surprising thing was that Freeguino really worked. I want to share my experience with you. What is Freeduino? It is an Arduino UNO board without any circuit boards. It uses a technology called freeform to interconnect components through wires or copper wires rather than circuit boards. [...]
Printed circuit board can be divided into rigid printed circuit board and flexible printed circuit board according to the production materials. Flexible circuit board is commonly known as FPC, that is, printed circuit board made of flexible insulating substrate. It is mainly used for communication, mobile phones, laptops, LCD and other products. In addition, some [...]
In the process of PCB copying, it is necessary to disassemble the circuit board, dismantle the integrated circuit and other components to make a BOM list, and scan and copy the disassembled bare PCB. Therefore, it is also an important topic to correctly disassemble the integrated circuit on the PCB in this process. Not only [...]
As there are still many market variables in the near future, it is expected that the market situation in the third quarter will be similar to that in the second quarter. Among them, high-density junction boards (HDI circuit boards) will benefit and enter the peak season. The demand and crop movement rate are expected to [...]
