This Ceramic Heating Core is specifically engineered for high-performance hot air rework stations and industrial heat guns. By utilizing an advanced co-fired ceramic structure, the heating circuit is fully embedded within the substrate, allowing for direct and efficient heat transfer to the passing airflow. Unlike traditional quartz-tube heaters with exposed wires, our ceramic cores are immune to oxidation and mechanical vibration, ensuring a stable and clean hot air stream. Its superior thermal shock resistance allows it to handle rapid start-stops and high-volume airflow without cracking, making it the ideal choice for lead-free BGA rework and precise industrial thermal processing.
Key Features
