Material Architecture of the HA80 Series

The HA80 Series Aluminum Circuit Board is built on a multi-layer structure, each component tailored to enhance thermal efficiency and electrical performance:

Core Layer Composition

Aluminum Substrate: The foundational layer, selected for its high thermal conductivity and mechanical rigidity. Unlike generic aluminum substrates, the HA80 Series uses specially treated aluminum alloys that balance heat dissipation with resistance to corrosion and warping, ensuring stability in both high-temperature and humid environments.

Optimized Dielectric Layer: A proprietary dielectric material positioned between the aluminum substrate and copper circuit layer. Formulated with ceramic-reinforced polymers or high-temperature epoxies, this layer minimizes thermal resistance while maintaining high electrical insulation strength. Its low dielectric loss (Df) ensures signal integrity in high-frequency applications, distinguishing it from standard aluminum circuit boards.

High-Purity Copper Circuit Layer: Bonded to the dielectric via advanced lamination techniques, the copper layer features ultra-smooth surfaces and uniform thickness to reduce electrical resistance and enhance heat spreading. This precision ensures reliable current distribution and efficient thermal transfer from active components to the aluminum substrate.

This architecture creates a synergistic thermal-electrical system, where heat is rapidly routed away from critical components while electrical signals propagate with minimal loss—a hallmark of the HA80 Series.
