Dry box storage guidelines
IC packages are compromised within 24 hours, after they left the Moisture barrier bags (MBBs). They continuously absorb moisture from the humidity in the air, resulting in micro-cracks during reflow heating.
Performance of Mcdry
Our solutions provide optimal ultra-low humidity and moisture-proof storage for IC packages. Moisture-sensitive components have an indefinite floor-life and micro-cracking or pop-corning during the reflow process is not an issue.
Moisture absorption and dehumidification data
We gathered various Data with different conditions to verify the quality of our system. Our powerful Zeoluite enables you to interact every 10min for a 2min opening time.
McDry is your way to Just-in-time-Production.
How to store
IC packages
Low humidity storage of sensitive Surface Mount Devices as specified by IPC/JEDEC J-STD-033C. To prevent micro-cracking, moisture containing IC's and LEDs can be baked or stored in McDry.
Antistatic countermeasure
Electrostatic discharge destroys electronic devices. In order to prevent this, the antistatic
measures are applied on Mcdry and McDRY complies with IEC61340-5-1.
IC Package storage specified by IPC-JEDEC
Mcdry is recommended for IC Package Storage after Opening Moisture-Barrier Bags. As specified by IPC/JEDEC J-STD-033C.
ordinary storage
Atmospherical moisture diffuses in the IC during storage.
reflow process
Moisture gathering,
pressure increase
The interface between the die pad and resin is peeled by the water vapor pressure during reflow heating
reflow process
The package is blown by expanding moisture
Further heating causes the vapor to expand, stretching the package.
reflow process
The Packaging releases the water due to pressure, forcing cracks
Is the power connected?
Check Indicator at the front. There should be a green LED visible.
Is the correct voltage used?
Was there a Power Surge in your System?
Is the humidity Meter and F Switch set “ON” ?
Is the humidity meter calibrated properly?
Is a LED blinking on the display of the humidity meter?
Are there any physical problems with your unit?
