PCB design is the design of the pointer to the circuit board. Circuit board design is based on the circuit diagram, circuit designers need to achieve the functions. PCB design mainly refers to layout design, which needs to consider various factors such as the layout of external connections, the optimal layout of internal electronic components, [...]
1. Use good grounding method Ensure that the design has adequate bypass capacitance and floor plan. When using an integrated circuit, be sure to use the appropriate decoupling capacitors near the power supply end to the ground (preferably the ground plane). The appropriate capacitance depends on the specific application, capacitance technology and operating frequency. The [...]
[global output value of PCB industry in 2024 May exceed $75 billion, and high-end PCB products have a large growth space] The global printed circuit board (PCB) industry has a long history and has gone through several cycles. In 2017, the global output value of PCB industry was usd 58.84 billion, up by 8.5% year [...]
It is easy to form parasitic capacitance by placing two close wires on the PCB. Because of this capacitance, a rapid voltage change on one line produces a current signal on the other The digital switch action is separated from the analog circuit, and the digital and analog parts of the circuit are separated. (right) [...]
