Circuit Block Assembly Thermal Management with RF Noise Isolation

The heat dissipation system is segmented into multiple independent metal heat spreaders, each dedicated to a specific circuit block. This segmentation prevents the formation of continuous metal pathways that would transmit radio frequency noise between different circuit blocks, while still providing effective heat dissipation for each individual block through its own heat spreader.

Non-conductive adhesive layers are introduced as intermediary materials between the metal heat spreaders and the circuit blocks, and between heat spreaders and surrounding structures. These intermediaries maintain thermal contact for heat dissipation while electrically isolating the metal components, thereby preventing radio frequency noise transmission through the heat spreader system.

The electronic device is divided into multiple independent circuit blocks, each with its own dedicated metal heat spreader. This segmentation allows flexible arrangement and modularization for design freedom, while ensuring that each block maintains efficient heat dissipation through its own heat spreader without relying on shared thermal pathways.

Each circuit block is equipped with its own metal heat spreader tailored to the specific thermal requirements of that block. This local quality approach ensures that heat dissipation is optimized for each individual module, maintaining high thermal efficiency despite the modularized structure that provides design flexibility.
