Something We Need to Know About Dry Box for Electronic Components

When it comes to electronic components, moisture can pose a major problem.  Moisture can cause corrosion, mold, and short circuits.  To protect electronic components from moisture, using a dry box is essential.  A dry box is an airtight container that stores electronic components in a low humidity environment.  In this blog, we will discuss what a dry box is, how it works, and why it is important.  We will also look at the different types of dry boxes available in the market.  Finally, we will discuss the importance of using a dry box dehumidifier in your dry box.


A dry box for electronic components is a storage cabinet that maintains a low humidity environment.  The humidity level in a dry box is typically below 5% RH.  Dry boxes are used to store electronic components that are sensitive to moisture.  These components include circuit boards, semiconductors, sensors, and other devices.  Dry boxes are commonly used in industries such as aerospace, defense, semiconductor manufacturing, and research laboratories.


How Does a Dry Box Work?


A dry box works by removing humidity from the air inside the cabinet.  The cabinet is sealed to prevent moisture from entering.  The inside of the cabinet is lined with a desiccant material such as silica gel.  The desiccant material absorbs moisture from the air, keeping the humidity level low.  A dry box also has a hygrometer to monitor the humidity level inside the cabinet.  Some dry boxes also have a nitrogen purge system, which replaces air with nitrogen gas to further reduce the humidity level.


Types of Dry Boxes Available in the Market


There are different types of dry boxes available in the market.  The most common types are the desiccant dry box, nitrogen purge dry box, and automatic dry box.  A desiccant dry box uses a desiccant material to absorb moisture from the air.  A nitrogen purge dry box replaces air with nitrogen gas to reduce the humidity level.  An automatic dry box uses a combination of a desiccant material and a nitrogen purge system to maintain a low humidity environment.


Why is a Dry Box Important?


Moisture can damage electronic components and cause them to malfunction or fail.  Moisture can cause corrosion, mold, and short circuits.  Using a dry box for electronic components ensures that they are stored in a low humidity environment, preventing moisture from causing any damage.  Storing electronic components in a dry box also prolongs their lifespan and ensures their reliability.


Using a Dry Box Dehumidifier


A dry box dehumidifier is a device that removes moisture from the air inside the dry box.  A dry box dehumidifier is essential to ensure that the humidity level inside the dry box remains low.  Without a dry box dehumidifier, the desiccant material in the dry box will eventually become saturated and lose its effectiveness.  There are different types of dry box dehumidifiers available, including electric dehumidifiers, rechargeable dehumidifiers, and desiccant bags.  It is important to choose a dehumidifier that is suitable for the size of the dry box.


Differences Between Humidity Storage Cabinet and Dry Box Dehumidifier


A humidity storage cabinet and a dry box dehumidifier are both used to protect humidity-sensitive items from moisture damage. However, there are some differences in their design and function:


  • Design: A humidity storage cabinet usually has a larger capacity than a dry box dehumidifier. It is designed to store items in bulk, whereas a dry box dehumidifier is compact, designed to store smaller items such as cameras and lenses.

  • Humidity Control: A humidity storage cabinet controls the relative humidity by stabilizing the air inside, while a dry box dehumidifier uses a desiccant or a dehumidifying unit to remove moisture from the air.

  • Power Consumption: A humidity storage cabinet requires more power to operate since the cabinet has larger dimensions, which means it requires more energy to maintain stable humidity levels compared to a dry box dehumidifier

  • Accessibility: A dry box dehumidifier is portable, lightweight and more easily accessible than a humidity storage cabinet. It can be carried around and used in different locations, while a humidity storage cabinet is usually installed in a fixed position.


Overall, a humidity storage cabinet and a dry box dehumidifier serve similar functions, but there are differences in their design and applications. The choice between them depends on the type of items or equipment that needs to be protected and the level of humidity control required.


A dry box for electronic components is essential to protect them from moisture.  Moisture can cause damage to electronic components, reducing their lifespan and reliability.  A dry box operates by absorbing moisture from the air inside the cabinet.  There are different types of dry boxes, including desiccant dry boxes, nitrogen purge dry boxes, and automatic dry boxes.  Using a dry box dehumidifier is important to ensure that the humidity level inside the dry box remains low.  Using a dry box for electronic components is a necessary investment for anyone who wants to protect their electronic components from moisture.
