Blind and buried vias PCB relies on precise fabrication to enable dense, efficient layouts. By limiting via paths to necessary layers, it reduces signal loss, making it vital for high-performance devices。
Blind and buried vias manufacturing is a critical process in PCB design, enabling high-density interconnects and improved signal integrity. This technology is essential for modern electronic devices requiring compact and efficient designs。
Blind and buried vias fabrication specifications cover hole diameter (ranging from 0.075mm for laser – drilled micro-vias to over 0.2mm for mechanical drilling), depth based on layer thickness, and plating thickness (usually 25 – 50μm). Alignment tolerances of ±50μm are common。
Blind and buried vias fabrication enhances high-density PCBs with better signal integrity, thermal management, critical for advanced electronics, aerospace, medical devices。
