Combined with the dual characteristics of baking and dehumidification, the outer surface and inner deep water molecules of electronic parts are fully excited to make them completely dry. The dry cabinet with 40 ℃ micro temperature to force water molecules to evaporate from the inside of the parts, and then the dehumidifier host completely absorbs the water molecules in the air in the cabinet and discharges them out of the cabinet, so the dryness can reach below 5% RH. It can not only avoid the potential thermal damage and oxidation of electronic parts when baking in the traditional high tenperature drying oven, baking dry cabinet can solve the problem of moisture attaching to the parts again after cooling.
