Some materials that are sensitive to air and have poor thermal stability need to be dried in a vacuum and pure box environment to remove water or solvent from the surface of the substrate inside the device, or to dry/cure sensitive materials under specific temperature conditions. Vacuum heating system is the most economical and effective product to realize these functions, with the highest temperature reaching 180°C.
When performing coaxial packaging or butterfly packaging for high-precision optical communication, laser and sensor devices, not only a closed inert gas environment is required, but also the water and oxygen content in the box body needs to be kept less than 5PPM. In order to maintain the water and oxygen content stably within the specified numerical range, a gas purification system needs to be installed, which can circulate the gas in the glove box continuously, then through the gas purification equipment to remove the water oxygen and organic solvent impurities in the glove box.
