PCB board each layer function
The signal layers are all layers with electrical connections, which is the actual copper layer. Intermediate layer refers to the intermediate plate layer used for wiring, in which the wire is distributed.

Patch processing which good how to choose
In Shenzhen, there are a lot of patch processing manufacturers, these manufacturers are uneven in quality, the price is not the same, so before the production, you can choose the following advantages of the patch processing plant: a, a high degree of prof
Matters needing attention for component packaging in RF circuit
RF designs must be thoroughly and carefully planned at the beginning of the design process, with a thorough and continuous evaluation of progress at each design step.
The technical requirements of high speed and high frequency copper clad plate for 5G communication
Thin substrate material should be selected for 5G high-frequency plate. Meanwhile, material characteristics such as high thermal conductivity, smooth surface of copper foil and low loss factor should be selected to reduce heating.
PCB technical requirements and difficulties of 5G communication products
In order to alleviate this design pressure, communication chip manufacturers have to choose to develop higher speed IC products to meet the needs of large capacity and small volume products.
What are PCB high frequency plates? How to choose?
PCB board selection must meet the design requirements, mass production, cost balance. In short, the design requirements include both electrical and structural reliability.
Why did these PCB companies fail?
Needless to say, the PCB industry is facing increasing challenges and competition. But in trouble, lying flat can not save themselves, only fight, can be reversed.
Etching process of PCB outer circuit
This type of graphic plating is characterized by the presence of a copper coating only under the lead tin resist layer. Alternatively, the entire plate is coated with copper, with only tin or lead-tin resist outside the film
What are the key points of PCB wiring for surge prevention?
General engineers only consider the design of system functionality when designing, but it is possible that the system needs surge design, and the transient surge current should reach 3KA.
Use PCB holes to reduce EMI
The PCB mounting holes help secure the PCB to the housing. But this is its physical mechanical use, in addition, in electromagnetic function, PCB mounting hole can also be used to reduce electromagnetic interference.
How to improve the appearance quality of PCB solder resistance
how to improve the appearance quality of the printed circuit board flux resistance has become an urgent problem to be solved in every PCB factory. Factors that affect the appearance quality of solder resistance
High reliability PCBS generally have these characteristics
PCB as the core substrate of electronic products, its quality and reliability directly affect the quality and reliability of electronic products, so high reliability PCB has become the basic requirements of many electronic products.
