In the past, the wiring of a circuit was direct current in nature and the surrounding environment was not very important, but now it is necessary to control an electromagnetic field. The electromagnetic field is capacitive and the wire is close to its return path (high capacitance). It is also a mag... ...More>>
In the manufacture of high-speed PCB, the PCB must be selected to meet the design requirements, mass production, cost to strike a balance. In simple terms, the design requirements consist of electrical and structural reliability. In general, when designing very high speed PCB boards (frequencies gre... ...More>>

As electronic products are updated and iterated faster and faster, electronic design is constantly improving the performance of the whole machine, b... ...More>>
Most circuit board factories sometimes have this phenomenon, everyone in the factory is very busy, every department is busy, but the overall efficiency often fails to reach the target, and it is difficult to find out the reason, I do not know how to improve? The reasons are analyzed from eight aspec... ...More>>
The HDI is made of the following materials:copper foil: conductive graphic composition of the basic materialcore board (Core) : the skeleton of the circuit board, used for the inner production of the Core board.semi-cured sheet (Prepreg): multi-layer board production of indispensable material, the a... ...More>>
What should we pay attention to in the process of high-frequency plate processing?Impedance control requirements are relatively strict, and the relative line width control is very strict, generally about 2%.Due to the special plate, the adhesion of PTH copper sinking is not high. Generally, it is ne... ...More>>
Phenomenal versatility: HDI boards are ideal where weight, space, reliability, and performance are primary concerns.Compact design: The combination of blind vias, buried vias, and microvias brings down the board space requirement.Better signal integrity: HDI incorporates via-in-pad and blind via tec... ...More>>
