The special crane for the semiconductor clean room is an important equipment for material handling in the semiconductor workshop. The clean room crane is required for semiconductor operation, because the tinyest dust will destroy the function of the whole chip. The clean room is an environmental control facility that produces products that are defined as specially constructed enclosed spaces. Airborne contaminants are subject to airborne particulates, temperature, humidity, air pressure, airflow patterns, air movement, vibrational height control, noise, and biology. And lighting. The clean room has strict rules and procedures to prevent semiconductor contamination. Because there is no effective control, the pollution may be harmful to the product. The dust-free clean crane is an essential equipment for semiconductor production.
