amber devices. This tape also protects the LED during the soldering process and
should be left in place until initial operation.

Projection Power
B. General Handling recommendations
The use of any type of sharp objects should generally be avoided, since this can
damage the component. Generally the LED light-emitting area should not be
touched or punctured as this can damage the component.
ESD stability
All OSRAM OSTAR
®
Projection devices offer a build-in 2kV ESD providing ESD
stability of up to 2 kV. It is assigned to the “Class 2 HBM” category in accordance
with ANSI / ESDA / JEDEC JS-001. With this class the LED can be considered
as uncritical for processing and assembly by state-of-the-art SMT equipment
aligned with ESD precautions. To achieve higher ESD protection on the system
level, additional ESD protection must be applied.
Nevertheless, please be aware of ESD safety precautions while handling LEDs.
As a matter of principle, common ESD safety precautions must be observed
during the handling, assembly and production of electronic devices (LEDs). For
further information about ESD protection please refer to the application note
“ESD protection while handling LEDs”.
Cleaning
Any direct mechanical or chemical cleaning of the LED should be avoided. For
dusty LEDs, simple cleaning by means of purified compressed air (e.g. central
supply or spray can) is recommended. In order to ensure that the compressed
air does not contain any oil residues, the use of a spray can is recommended. A
maximum pressure of 4 bar at a distance of 20 cm to the component is also
recommended.
