Key Differences Between PCB and HDI Circuit Boards
While both fabricated circuit (PCB) and High-Density Interconnect (HDI) circuit serve as the foundation for electrical devices, they exhibit notable distinctions. PCBs typically utilize plated vias, which are relatively significant and conventional to create. HDI boards, conversely, employ tiny – vias formed with diameters of 0.1mm or fewer – and photo drilled vias and sequential build techniques. This enables considerably higher component concentration on HDI boards, minimizing the overall platform footprint and optimizing power quality. Consequently, HDI boards are often employed in miniature and more complex uses like portable gadgets and portable systems where space is limited, whereas PCBs are electronic manufacturing services more generally utilized in less applications.
- PCBs: larger vias, simpler manufacture
- HDIs: small vias, higher density
Designing for Performance: Considerations for Multilayer PCBs
