DESCRIPTION

The VLMW71.. is one of the most robust and light
efficient LEDs in the market. With its extremely high
level of brightness and the ultra low high profile, which
is only 1.5 mm are highly suitable for both conventional
lighting and specialized application such as
automotive signal lights, traffic lights, channel lights,
tube lights and garden lights among others.

DRY PACKING

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

Aluminum bag

20613

RECOMMENDED METHOD OF STORAGE

Dry box storage is recommended as soon as the
aluminum 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 672 h 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 h at 40 °C + 5 °C/- 0 °C and < 5 % RH
(dry air/nitrogen) or

96 h at 60 °C + 5 °C and < 5 % RH for all device
containers or

24 h at 100 °C + 5 °C not suitable for reel or tubes.
An EIA JEDEC standard JESD22-A112 level 2a label

is included on all dry bags.

CAUTION

1. Shelf life in sealed bag 12 months at <40°C and < 90% relative humidity (RH)

2. After this bag is opened devices that will be subjected to infrared reflow,
vapor-phase reflow, or equivalent processing (peak package body temp.

260°C) must be:

a) Mounted within
b) Stored at <1

3. Devices require baking before mounting if:
a) Humidity Indicator Card is >10% when read at 23°C +
b) 2a or 2b is not met.

4. If baking is required, devices may be baked for:

192 hours
96 hours
24 hours
