A good circuit board not only needs to achieve the functionality of the circuit design but also must consider electrical characteristics such as EMI, EMC, ESD (Electrostatic Discharge), and signal integrity. Additionally, mechanical structure and heat dissipation issues for high-power chips must be taken into account. On this basis, the aesthetic aspect of the circuit … Read more
Successful RF design requires careful attention to every step and detail throughout the design process. This means thorough and careful planning must be done at the start of the design phase, along with comprehensive and continuous evaluation of the progress of each design step. Such meticulous design skills are often lacking in the culture of … Read more
PCB grounding is a concern for PCB layout engineers, such as how to effectively plan a grounding system on the board, whether to wire analog, digital, and power grounds separately or together at a single point, and how to eliminate ground loops on the circuit board. Today, we will mainly discuss PCB grounding design, PCB … Read more
TOP Mounting Target On Paste Due to the ultra-thin and flexible characteristics of FPC (Flexible Printed Circuits), it is widely used in the sliding and bending parts of small electronic devices, as well as in the three-dimensional layout of small mobile terminals like smartphones and wearable devices. However, despite the widespread application of flexible circuit … Read more
In microcontroller systems, the issue of electromagnetic compatibility (EMC) is one of the most challenging to resolve. It primarily stems from electromagnetic interference (EMI) both inside and outside the system, which can easily lead to abnormal operation of the microcontroller, thereby affecting the stability and reliability of the entire system. Therefore, it is essential to … Read more

With the emergence of high-speed DSP (Digital Signal Processors) and peripherals, new product designers face an increasingly severe threat from electromagnetic interference (EMI). Initially, the issues of transmission and interference were referred to as EMI or RFI (Radio Frequency Interference). Now, a more definitive term, “interference compatibility,” is used instead. Electromagnetic compatibility (EMC) encompasses both … Read more
In high-speed digital signal processing (DSP) systems, electromagnetic interference (EMI) is a critical issue that cannot be overlooked. Due to the high-frequency signal processing and complex circuit layouts involved in DSP systems, the electromagnetic environment becomes more complicated, easily leading to signal distortion, system instability, and even functional failure. Therefore, engineers need to understand the … Read more
