Precision-Engineered Multilayer Connectivity Solutions
Our buried via PCBs deliver superior internal layer interconnections for high-density, high-performance electronic applications. These advanced circuit boards feature strategically placed vias that connect internal copper layers without extending to the outer surfaces, maximizing routing density while maintaining signal integrity.
Key Features:
- Space-Efficient Design: Vias terminate within the PCB stack-up, freeing valuable surface area for component placement and additional routing
- Enhanced Signal Performance: Shorter via lengths reduce parasitic inductance and capacitance, improving high-frequency signal transmission
- Increased Routing Density: Enables complex multilayer designs with up to 20+ layers while maintaining compact form factors
- Superior Electrical Isolation: Internal connections provide excellent crosstalk reduction and electromagnetic interference shielding
Technical Specifications:
- Via diameter: 0.1mm to 0.2mm (4-8 mils)
- Aspect ratio: Up to 8:1 for reliable plating
- Layer count: 4 to 24+ layers
- Material compatibility: FR-4, Rogers, polyimide, and other high-performance substrates
- Impedance control: ยฑ5% tolerance for controlled impedance applications
Applications:
- High-speed digital processors and memory modules
- RF/microwave communication systems
- Aerospace and defense electronics
- Medical devices requiring miniaturization
- Advanced automotive electronics
- Server and networking equipment
Quality Assurance: Every buried via PCB undergoes rigorous electrical testing, cross-sectional analysis, and reliability validation to ensure consistent performance in demanding applications. Our manufacturing process meets IPC Class 2 and Class 3 standards with full traceability.
