Why use smart moisture cabinets?

Why use smart moisture cabinets? Most electronic products require operation and storage in dry conditions. According to statistics, more than a quarter of industrial manufacturing defective products are related to moisture hazards every year. For the electronics industry, the hazard of moisture has become one of the main factors in product quality control.

(1) Integrated circuit: The damage of moisture to the semiconductor industry is mainly manifested in moisture that penetrates and adheres to the inside of the IC. Water vapor is formed in the heating process of the SMT process, and the generated pressure causes the IC resin package to crack and the metal inside the IC device. Oxidation causes product failure. In addition, when the device is soldered during the PCB board, the solder joint pressure will also cause the solder joint.

(2) Liquid crystal device: The glass substrate, polarizer and filter lens of liquid crystal device such as liquid crystal display should be cleaned and dried in the production process, but it will still be affected by moisture after cooling, reducing the yield of the product. . Therefore, it should be stored in a dry environment after washing and drying.

(3) Other electronic devices: capacitors, ceramic devices, connectors, switch parts, solder, PCB, crystal, silicon wafer, quartz oscillator, SMT adhesive, electrode material adhesive, electronic paste, high-brightness device, etc. Will be exposed to moisture.

(4) Electronic components during operation: semi-finished products in the package to the next process; before and after the PCB package and between the power supply; IC, BGA, PCB, etc. after unpacking but not used up; waiting for the tin furnace Soldering devices; devices that have been baked to be warmed up; products that have not been packaged are subject to moisture.
