Puwei's AlN Coated Copper Direct Bonded Copper (DBC) Substrate is a premium engineered solution designed to revolutionize thermal management in advanced thermoelectric modules. By integrating high-purity Aluminum Nitride (AlN) ceramic with robust copper layers, this substrate delivers unparalleled heat dissipation and electrical isolation, making it a critical component for demanding applications in Power Devices, Microelectronics Packaging, and high-efficiency Thermoelectric Semiconductor Module Plates. It is the ideal foundation for applications leveraging the Peltier effect for precise cooling or power generation.
Optimized AlN DBC substrate for enhanced thermoelectric module performance.
Reliable thermal management core for Thermoelectric Cooling (TEC) systems.
Comprehensive performance data ensuring informed design decisions.
This substrate functions as the backbone of a thermoelectric module. When current flows through the semiconductor elements (utilizing the Peltier effect), heat is pumped from one side to the other. Our substrate's copper layers efficiently distribute current and transfer heat, while the AlN ceramic provides essential electrical isolation and minimal thermal resistance, maximizing energy conversion efficiency. This principle is crucial for Thermoelectric Modules for Electric Power Generation and precision cooling systems.
Medical diagnostic equipment, laboratory instruments, and CCD cooling where stability is critical for Sensor Packaging.
Converting waste heat from automotive exhaust or industrial processes into usable electricity.
Thermal stabilization for high-power laser diodes, RF amplifiers (Microwave Components), and High-Power Microelectronic Components.
Battery thermal management in EVs, seat climate control, and avionics cooling requiring extreme reliability.
Every Puwei AlN DBC Substrate is produced under a stringent quality management system (ISO 9001) and complies with RoHS/REACH directives. Our vertical integration from material selection to precision machining ensures traceability and consistency, providing you with a reliable Bare Ceramic Plate ready for high-yield assembly.
We specialize in tailoring solutions to your exact needs. Our capabilities include:
