The grounding problem of electronic products is a common topic. This article only talks about a small part of it, mainly the grounding problem of the metal case and the circuit board. We often see that in some system designs, a high-voltage capacitor C1 (1~100nF/2KV) is usually connected in parallel with a large resistor R1…
1 Introduction With the continuous increase in the main frequency of embedded microprocessors, the transmission and processing speed of signals is getting faster and faster. When the system clock frequency reaches above 100MHZ, traditional circuit design methods and software can no longer meet the requirements of high-speed circuit design. In high-speed circuit design, the equal…
The first PCB wiring In PCB design, wiring is an important step to complete product design. It can be said that the previous preparations are all done for it. In the entire PCB, the design process of wiring is the most limited, the most skillful, and the most labor-intensive. PCB wiring includes single-sided wiring, double-sided…
Designing and building the next generation of electronic products is a complex process, especially in a highly competitive global industry such as electronics, where rapid and continuous technological changes have become the norm and the rule of innovation. If designers fail to embrace these changes, they will face the risk of being left behind by…
Introduction With the widespread application of DSP (digital signal processor), the design of high-speed signal processing PCB board based on DSP is particularly important. In a DSP system, the operating frequency of DSP microprocessor can be as high as hundreds of MHz, and its reset line, interrupt line and control line, integrated circuit switch, high-precision…
