Flexible Structure and Layer Count Options
The number of layers in a Multilayer Rigid PCB can be flexibly customized to meet application requirements:
- Common 6 Layer Rigid PCB and 8 Layer Rigid PCB configurations are suitable for most mid- to high-end electronic products.
- High-end applications can require 12 layers or even several dozen. Shenzhen STHL Technology Co., Ltd. can manufacture rigid multilayer PCBs with up to 56 layers.
- The greater the number of layers, the more refined the allocation of signal, power, and ground planes, improving signal integrity and electromagnetic compatibility.
For applications that demand high-speed signal transmission in limited space, High-Density Rigid PCB designs often incorporate advanced processes such as blind vias, buried vias, and microvias, enabling more compact routing and more efficient interconnections.
Core Materials and Layer Structure
Process and Performance Advantages
- Signal Integrity: High-speed signal layers sandwiched between ground planes reduce crosstalk and reflections
- Optimized Power Distribution: Independent power and ground planes lower impedance and noise
- Structural Stability: Rigid substrates and precise stack-up processes ensure long-term reliability
- High Wiring Density: Multi-Layer Rigid PCBs enable complex layouts in limited space, accommodating high-pin-count devices
- Reliable Interconnect: High-precision drilling and copper plating ensure stable via conductivity
Typical Application Areas
- Communications Equipment: 5G base station main control boards, optical modules
- Computers and Servers: Motherboards, graphics cards, storage expansion cards
- Automotive Electronics: ADAS control units, in-vehicle infotainment systems
- Medical Equipment: High-precision imaging systems, portable diagnostic devices
- Industrial Control: Robot control boards, PLC core modules
In these applications, Multilayer Rigid PCBs must not only meet high-speed, high-frequency electrical performance requirements but also ensure long-term stability and environmental durability.
