The Electronic Humidity Control Cabinet utilizes the principle of vapor pressure equilibrium. This means that water molecules in the air are in constant, random, and high-speed motion, causing them to spread from areas of high density (the center) to areas of low density (the center) until the air is evenly hydrated, achieving humidity balance. The electronic cabinet can store items in a relatively sealed and controlled environment.

Create a moisture and oxidation-proof environment to prevent moisture absorption, deliquescence, and oxidation. The electronic desiccator is composed of a molecular sieve made of hygroscopic polymer materials that absorb water molecules. Through a memory action, it controls the moisture absorption and exhaust cycle between the inner and outer doors, expelling water molecules from the desiccator to the outside. Throughout the process, water molecules remain in a gaseous state, without any heat absorption or release.

Therefore, it also ensures the stability of the internal temperature, and is also known as a constant temperature dehumidifying cabinet. During the baking process, be mindful not to cause the material trays to release unknown gases, as this may affect the welding properties of the equipment. It is essential to keep detailed baking records during the baking process to control the baking time. After several cycles of reflow welding or rework, it cannot replace the drying process. Some SMD components and motherboards cannot withstand long periods of high-temperature baking, such as some FR-4 materials, which cannot tolerate 24 hours of baking at 125℃; some batteries and electrolytic capacitors are also very sensitive to temperature. Considering these factors, the MSD-SUN electronic desiccator can be chosen to control the drying process.
