Influence of slotting on EMC performance of PCB board
The generation of grooving can be summarized into the following two cases :1. Grooving caused by power/ground plane segmentation; 2.the through hole is too dense to form grooves.

In PCB design, these spacing is not considered, which may lead to design failure
There are many aspects of PCB design that need to take into account the safe spacing. It is classified into two categories: one is electrical related safety spacing and the other is non-electrical related safety spacing.
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.
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 Introduction to printed circuit boards
In this way, the printed circuit or printed circuit of the finished board called printed circuit board, also known as printed board or printed circuit board.
Overview of high precision technology of printed board PCB
Buried, blind hole structure of the printed circuit board, generally use the "sub-board" production mode to complete, which means that after several times of pressing plate, drilling, hole plating and so on to complete, so precise positioning is...
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, circuit board, circuit board
There are many kinds and numbers of holes and complex shapes of single-sided paper substrate and double-sided non-metallic holes of epoxy glass cloth substrate.
Brief discussion on several important technical properties of PCB ink
It is a short name for dynamicviscosity. The viscosity is generally expressed in terms of the shear stress of the fluid flow divided by the velocity gradient in the direction of the flow layer in international units of Pa/s (Pa). S) or millipa/second (mPa
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.
How to check spot welding quality in SMT patch processing
For electronic devices, a certain amount of heat is generated during operation. If the heat is not released in time, the devices will continue to heat up, and the devices will fail due to overheating, and the reliability of the devices will be reduced. Th
