Flexible Aluminum CCLs

Boyu’s flexible aluminum CCLs redefine possibilities in form factor design:

Bendable Laminates: Utilizing thin-gauge aluminum cores (≤0.2mm) and elastic dielectric materials like silicone-polyimide blends, these CCLs withstand repeated bending cycles (up to 100,000+ cycles) without performance degradation. Ideal for wearable health monitors, curved automotive displays, and foldable smartphones, they balance mechanical flexibility with thermal conductivity.

Conformal Electronics: Adhesive-backed variants enable seamless integration onto 3D surfaces, such as drone frames and industrial pipes, expanding the scope of smart sensing applications.

High-Frequency Aluminum CCLs

Catering to next-generation communication technologies:

Low-Dk Dielectrics: Proprietary formulations with dielectric constants (Dk) as low as 2.4 at 10 GHz minimize signal delay in 6G R&D and satellite communication systems. These laminates support data rates exceeding multi-Gbps, critical for ultra-high-speed networks.

Controlled Impedance Designs: Precision-engineered copper trace geometries and dielectric thicknesses ensure consistent impedance (±5%) across large panels, reducing signal reflection in radar and phased array antennas.

Heavy-Copper Aluminum CCLs

For power-intensive applications:

Thick Copper Cladding: Laminates with copper weights exceeding standard configurations support high-current distribution in industrial motor drives and EV battery busbars. The aluminum core dissipates resistive heat generated in heavy copper traces, preventing thermal overload.

Hybrid Bonding: A combination of mechanical interlocking and chemical adhesion ensures robust bonding between thick copper and aluminum, critical for vibration-prone environments like construction equipment.
