A dry box for electronic components is a humidity-controlled storage cabinet designed to protect sensitive electronic parts and devices from moisture-related issues like micro-cracks, and electrostatic discharge (ESD). Ideal for items such as semiconductors, PCBs (Printed Circuit Boards), and other moisture-sensitive devices, the dry box creates a stable, low-humidity environment to ensure long-term preservation.
Humidity is a serious concern in the EMS industry, particularly when dealing with sensitive components such as PCBs, chips, and other microelectronic devices.
Once a microcrack starts to form, moisture can be drawn deeper into the material through capillary action, further exacerbating the cracking. In semiconductors and high-precision electronics, this can degrade performance by allowing additional contaminants and moisture into sensitive areas.
How to prevent microcracks?
Humidity-Controlled Storage: Storing electronics in controlled, low-humidity environments (such as dry cabinets or dehumidified rooms) can reduce exposure to moisture.
Protective Conformal Coatings: Conformal coatings applied over circuit boards can shield components from moisture.
Proper Packaging: Moisture-barrier packaging for storage and transportation can keep sensitive components protected.

A dry box for electronic components, also called auto dry cabinet, adopts the latest dehumidifying technology. The entire dehumidifying system is controlled by a microcomputer. When the internal humidity is high, it starts to absorb moisture; when the humidity reaches the set value, it stops absorbing water and discharges water outside. This process is automatic, by maintaining low humidity and stable conditions, dehumidifying dry cabinets effectively protect valuable and sensitive items from the damaging effects of moisture.
This chart shows, in the ambient 25 degree C, humidity 50%RH, open door 30 seconds and then close, the humidity can recover to the set point within 30 minutes.
Drying and storage cabinets offer protection, reliability, and convenience, making them an invaluable tool for preserving sensitive items.
