Multiply-Layer Rigid PCB

KunXiang Multiply-Layer Rigid PCB, commonly referred to as multilayer PCB, is an essential component in electronic products, particularly in complex and high-performance electronic devices.

Definition: A multilayer PCB refers to a conductive system with multiple conductive layers stacked on a base plate, forming a three-dimensional conductive structure.Structure: Multilayer PCBs typically consist of four to thirty-six layers, with each layer composed of copper foil and insulating layers. Common conductive materials include copper, gold, aluminum, etc.

Functions

Improved Signal Transmission Speed: By increasing the number of layers, multilayer PCBs can effectively enhance signal transmission speed, thereby improving the overall performance of electronic products.

Reduced Signal Transmission Delay: The multilayer PCB design can effectively reduce interference and loss during signal transmission, thus minimizing signal transmission delay.

Enhanced Anti-Interference Capability: By utilizing different conductive materials and interlayer isolation techniques, multilayer PCBs can enhance the anti-interference capabilities of electronic products.

Space Saving: Multilayer PCBs allow for the integration of more functional modules within a limited space, saving on hardware space in electronic products.

The design of multilayer PCBs involves optimizing the routing of internal electrical layers to achieve a more rational circuit board layout. In the production process, Core and PP (Prepreg, semi-solid sheet) are two essential components of PCBs. Cores are used for conductive layers, while PP serves as a filler and adhesive. Typically, the number of impregnated layers (PP) does not exceed three to ensure consistent impedance control.

In summary, multilayer PCBs play a crucial role in electronic products due to their superior performance and wide range of applications.
