Perfect ultra-low RH storage in HuiTong Dry-Cabinet
Once parts have been removed from their moisture barrier bags and placed safety in SUPER DRY defects at the end of the line will be reduced.
The mechanism of micro-crack in Integrated Circuits (ICs) packages
Before reflow
Reflow process

Normal Storage
Moisture in the air is absorbed in the package.
Delamination by heating at the first stage.
As process goes on,more pressure by heating will make the delamination become bigger.
The pressure from delamination makes cracks in the packages.
Cracks do not make any defects at first,however it gradually corrodes the IC chip.
HuiTng DRY-Cabinet Storage
HuiTng DRY-Cabinet can dehumidify micro-moisture absorbed in the package.
JEDEC/IPC suggests the storage of device should be under 10%RH.
HuiTng DRY-Cabinet ensures high quality control for production with it ultra low humidity control.
HYPERr series are recommended for the storage of IC packages during its production process. For faster dehumidification for taping devices, MT series are recommended.
