Structure and Materials of Hybrid PCBs
What Makes a PCB "Hybrid"?
Hybrid PCBs integrate diverse materials (e.g., PTFE, ceramics, polyimides) unlike single-material FR-4 boards. This blend:
Enhances performance in high-heat or high-frequency environments.
Balances strength (FR-4) with signal efficiency (PTFE).
Common Materials and Their Roles
Material Type Description PTFE Minimizes signal loss in RF applications. FR-4 Provides structural rigidity as a base material. Polyimide Withstands high temperatures and offers flexibility. Ceramics Manages heat and supports high-frequency signals. Conductors Copper, gold, or silver for electrical pathways.
Material Combinations for Performance
Benefit How Material Mixing Helps Signal Transmission PTFE reduces signal degradation in RF systems. Thermal Management Ceramics dissipate heat in power-dense areas. Mechanical Strength FR-4 reinforces flexible layers (e.g., polyimide). Cost Efficiency Targeted material use avoids over-engineering.
