Heavy Copper PCB Circuit Boards 3-20 oz/ft² for Power Supplies & Automotive Electronics with 48 Layers
Heavy copper PCBs feature significantly thicker copper layers ranging from 3 oz/ft² to 20 oz/ft², providing enhanced current-carrying capacity for high-power applications where standard PCBs (typically under 2 oz/ft²) are insufficient.
Minimizes signal loss and distortion, ensuring clear data transmission even at elevated frequencies for telecommunications and data applications.
Utilizes materials with low dielectric constants and loss tangents to reduce energy loss during signal transmission.
Withstands elevated temperatures without degradation, maintaining reliability in demanding applications that generate significant heat.
Enables precise impedance control critical for maintaining signal quality and minimizing reflections in RF and microwave applications.
Exhibits superior electromagnetic compatibility by minimizing EMI and enhancing signal integrity through specialized material characteristics.
