Dry Packing
The reel is packed in an anti-humidity bag to protect
the devices from absorbing moisture during
transportation and storage.

Final Packing
The sealed reel is packed into a cardboard box. A
secondary cardboard box is used for shipping
purposes.
Recommended Method of Storage
Dry box storage is recommended as soon as the alu-
minium
bag has been opened to prevent moisture
absorption. The following conditions should be
observed, if dry boxes are not available:
• Storage temperature 10 °C to 30 °C
• Storage humidity ≤ 60 % RH max.
After more than 1 year under these conditions
moisture content will be too high for reflow soldering.
In case of moisture absorption, the devices will
recover
to the former condition by drying under the following
condition:
192 hours at 40 °C +5 °C/ -0 °C and < 5 % RH
(dry air/ nitrogen) or
96 hours at 60 °C +5 °C and < 5 % RH
for all device containers or
24 hours at 100 °C +5 °C
not suitable for reel or tubes.
An EIA JEDEC Standard JESD22-A112 Level 2 label
is included on all dry bags.
ESD Precaution
Proper storage and handling procedures should be
followed to prevent ESD damage to the devices
especially when they are removed from the Antistatic
Shielding Bag. Electro-Static Sensitive Devices
warning labels are on the packaging.

Bar-Code Labels
The Vishay Semiconductors standard bar-code labels
are printed at final packing areas. The labels are on
each packing unit and contain Vishay Telefunken
specific
data.
Assembly Instructions
Reflow Soldering
• Reflow soldering must be done within 1 year
stored under max. 30 °C, 60 % RH after opening
envelop
• Recommended soldering paste
(composition: SN 63 %, Pb 37 %)
Melting temperature 178 °C to 192 °C
• Apply solder paste to the specified soldering
pads, by using a dispenser or by screen printing.
• Recommended thickness of metal mask is 0.2 mm
for screen printing.
• The recommended reflow furnace is a
combinationtype with upper and lower heaters.
• Set the furnace temperatures for pre-heating and
heating in accordance with the reflow temperature
profile as shown below. Excercise extreme care to
keep the maximum temperature below 230 °C. The
