EMC specification for RF PCB design
In the actual design, the frequency, power rate and gain should be considered comprehensively to decide whether to add shielding plate.

Notes for RF circuit power supply design
Having a "noise-free" power supply is essential to optimizing system performance, although there are other factors that can degrade system performance in the actual design.
Reliability design of printed circuit board
It has been proved that the reliability of electronic equipment will be adversely affected even if the circuit diagram is designed correctly and the printed circuit board is not designed properly.
The basic method to minimize RF effect in PCB interconnect design
This paper introduces various techniques of the three types of interconnect design, including device installation methods, wiring isolation and measures to reduce lead inductance.
How to wire PCB design
No matter what work you are engaged in in the circuit board industry, if the circuit principle of electronic products is clear, you can improve the efficiency of functional testing and production efficiency of products. A trick takes you to understand the
PCB design for power processing and plane segmentation
In high speed PCB, RF energy is usually coupled between the power plane and the ground plane to become the edge flux leakage.
PCB design always have impedance discontinuity
In the process of transmission, if the characteristic impedance of the transmission path changes, the signal will reflect at the node where the impedance is discontinuous.
Common errors in PCB routing and differential signal design
Wiring is one of the most basic job skills of PCB design engineer. The quality of wiring will directly affect the performance of the whole system. Wiring is very important in high speed PCB design.
Several common errors in PCB differential signal design
For PCB engineers, the most important thing is to ensure that the advantages of differential routing can be fully utilized in the actual routing
How to avoid electromagnetic problems in PCB design
Emc and associated EMI have historically required the eyes of system design engineers, but today board designs and component packages are shrinking and Oems are demanding faster systems.
Rf circuit PCB design skills
The key of RF circuit PCB design is how to reduce circuit radiation and improve anti-interference ability, but in the actual layout and routing of some problems are in conflict with each other.
PCBA processing requirements for plug-in hole design and the DIP plug-in processing process of the patch factory
The processing of plug-in components generally adopts wave soldering. Because the wave soldering time is very short, if the jack is connected to more ground/electric layers, the tin penetration will be poor, resulting in poor welding.
