Photoelectric elements are extremely sensitive to dust as it can easily cause a short circuit. Therefore, a clean environment is necessary in the processing of photoelectric elements used for LED, LCD, semiconductor, and optical lens products. The cleanroom oven we provide is a class 100 drying unit which can lower the dust concentration to below 100 ×0.5μm, less than 3.5 particles per liter of air. Additionally, these cleanroom ovens are made from mirror like stainless steel and comes equipped with a highly efficient filter. It provides excellent airtightness through a full weld to satisfy your cleanliness requirements.
