1. Follow the layout principle of "first big, then small, first difficult, then easy", that is, the layout of important unit circuits and core components should be given priority. 2. The layout shall refer to the principle block diagram and arrange the main components according to the main signal flow pattern of the single board. [...]

Schematic diagram Ctrl+Backspace: repeat the previous operation Ctrl+Backspace: cancels [...]
In the process of PCB board design and manufacture, engineers should not only prevent PCB board from accidents during manufacturing and processing, but also avoid design mistakes. Today, banerjie summarized and analyzed common PCB problems, hoping to bring some help to your design and production work. The price is charged online on the jetpack website. [...]
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) [...]

The following jing state technical personnel and you talk. The interpolation and welding methods of integrated circuits and the interpolation and welding methods of discrete SMT [...]
Factors affecting PCB welding quality From PCB design to the completion of all components welding for a high quality circuit board, PCB design engineers and even the level of welding process, welding workers and many other links have strict control. It mainly includes the following factors: PCB diagram, quality of circuit board, quality of device, [...]
1. How to choose PCB board? The choice of PCB panel must meet the design requirements and the production and cost of the balance. Design requirements include electrical and mechanical parts. This material issue is usually important when designing very high speed PCB boards (frequencies greater than GHz). For example, the current commonly used fr-4 [...]
