Let's Be Our Agent
For the Storage of Semiconductor Devices
SUPER DRY, is the 1st auto-electronic desiccator that can maintain the ultra low humidity under 5%RH in the world, successfully marketing our products since 1974. SUPER DRY is designed to eliminate Moisture Sensitive Device (MSD) defects such as; micro-cracks, voids, depanaling and delamination etc. Currently more than 1400 company users including NASA, Intel etc over 26 countries have selected Totech’s auto-electronic desiccator to protect their valuable inventory.
IPC/JEDEC(J-STD-033A) - Handling standards of SMD
The mechanism of micro-crack in Intergrated Circuits (ICs) packages
Strategy against lead-free
SUPER DRY Application pattern at a semiconductor factory
SUPER DRY was the first dry cabinet introduced in many Japanese Semiconductor factories, SUPER DRY is widely used in various European and American factories. With SUPER DRY, the moisture related defects of IC packages and Printed Circuit Boards (PCBs) can be effectively and easily reduced or prevented. And with the introduction of lead-free processes the proper handling and care of MSD will become even more critical.

IPC/JEDEC Standard (J-STD-033A)
IPC/JEDEC has concluded the following joint standard for the handling SMD.
Moisture
Sensitivity
Level 2-4
Below 10% RHstorage is necessary. After the removal from a moisture barrier bag,the floor life of dry packages which is exposed under the environment not exceeding 30ºC and 60%RH can be reset, if they are placed in a dry box not greater than 10%RH for a minimum desiccating period of 5X the expose time.
Moisture
Sensitivity
Level 5-5a
Below 5% RHstorage is required. A minimum desiccating period of 10X the exposure time is necessary to dry the IC packages which are exposed not exceeding 30ºC and 60%RH after removing from a moisture barrier bag enough to reset their floor life.

241)	SUPER DRY is the only choice for your ultra-low humidity storage
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. Humidity Control Paradigm
Prefect ultra-low RH storage in SUPER DRY
Easy Operation: SUPER DRY is an electric appliance, so just plug it in before using.
Auto-recycling: Absorbed moisture is discharded as vapor without casing any problems of water leakage.
Cost-saving: The maintencance fee of SUPER DRY is only 1/20 compared with N2gas storage box.

The comparison between N2 gas storage and SUPER DRY storage

Moisture Sensitivity/Desiccant
Packaging/Handling of PSMCs (from Intel)
Products Humidity Setting and their Main features
Hyper series 1-50%RH (Drying Unit x 2)
Recommended whenever doors will be opened once an hour or once 2 hours.
02 series 2-50%RH (Drying Unit x 1)
Suitable for long term storage of MSD with infrequent door opening.

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.
SUPER DRY Storage
SUPER DRY can dehumidify micro-moisture absorbed in the package.  
JEDEC/IPC suggests the storage of device should be under 10%RH.  
SUPER DRY ensures high quality control for production with it ultra low humidity control.
HYPER series are recommended for the storage of IC packages during its production process. For faster dehumidification for taping devices, Easy Control series are recommended.
Strategy against Lead-free
Moisture trapped inside MSDs will cause defects during the reflow process. The introduction of a lead free process will only aggravate this reality. The data below shows that the vapor pressure becomes greater and greater with increasing reflow temperatures.
This vapor pressure can cause micro-cracking and delamination inside MSDs and in the end will result in failures, both at test and latent defects in the fields. With ultra-low humidity storage in SUPER DRY, the moisture inside IC packages can be dehumidified to nearly 0% preventing defects which can be caused by moisture absorption.
