The basic characteristic of the capacitor is to separate the straight connection. When the AC signal with DC bias passes through the coupling capacitor, the DC bias cannot pass through the capacitor, resulting in the bias of the AC signal becoming 0.
The miniaturization and thinness of electronic equipment inevitably use flexible PCB and rigid flexible combined PCB. With the expansion of applications, there will be many new performance requirements in addition to the increasing number of applications.
In order to improve the technical performance of the printed circuit board, we must first improve the performance of the printed circuit substrate board, and ensure the demand for high density and fine wire, copper foil, laminated insulating dielectric sh
The production process of soft and hard combined board has punching. Riveted. Laminate. Edge removal material. Drill holes. Remove glue residue. Copper sinking. PCB board surface plating. Outer dry film positive film production. Graphic plating. Alkaline
The disposal methods of waste PCB include crushing, separation, supercritical technology treatment, heat treatment (it mainly includes incineration, vacuum cracking, microwave, etc.), hydrometallurgy, biotechnology.
After the PCB size is determined, the pendulum position of the special component is determined. According to the function unit, the layout of all components of the circuit board.
The main heat dissipation methods of electronic components include natural heat dissipation or cooling, forced heat dissipation or cooling, liquid heat dissipation, cooling of heat dissipation or cooling, energy channeling in heat dissipation or cooling.
In the mobile phone terminal, the most important core is the RF circuit board and baseband circuit board. Rf circuit board responsible for RF transceiver, frequency synthesis, power amplification; Baseband circuit boards are responsible for signal process
Many design decisions affect the robustness of a high power inverter design. We need to evaluate the type of power switch, consider the operating voltage requirements, application dependencies, and how to power the secondary side of a half-bridge device.
Although the number of electronic components of printed circuit board is large, but its failure is regular to follow. Electronic components distribution order is to help customers professional, efficient, fast, high quality to solve the problem of multi-c
The life and performance of circuit board machining depend on the selection of PCB board. Fiberglass FR4 is the most common material used for PCB substrates. For flexible PCBS, use Clapton or equivalent plastic. PCBS made from cheaper materials such as ep
Make clear the components, general working principle, working process and signal flow, core components on the PCB board position. To analyze an electrical or electronic product, we first need to understand from the general, and then is the detailed analys
