7.CAUTIONS
(1) Lead Forming
· When forming leads, the leads should be bent at a point at least 3mm from the base of the epoxy bulb.
Do not use the base of the leadframe as a fulcrum during lead forming.
· Lead forming should be done before soldering.
· Do not apply any bending stress to the base of the lead. The stress to the base may damage the
BG-LED’s characteristics or it may break the BG-LEDs.
· When mounting the BG-LEDs onto a printed circuit board, the holes on the circuit board should be
exactly aligned with the leads of the BG-LEDs. If the BG-LEDs are mounted with stress at the leads,
it causes deterioration of the epoxy resin and this will degrade the BG-LEDs.
(2) Storage
· The BG-LEDs should be stored at 30°C or less and 70%RH or less after being shipped from Nichia and
the storage life limits are 3 months. If the BG-LEDs are stored for 3 months or more, they can be
stored for a year in a sealed container with a nitrogen atmosphere and moisture absorbent material.
· Nichia BG-LED electrode sections are comprised of a silver plated copper alloy. The silver surface
may be affected by environments which contain corrosive gases and so on. Please avoid conditions
which may cause the BG-LED to corrode, tarnish or discolor. This corrosion or discoloration may cause
difficulty during soldering operations. It is recommended that the BG-LEDs be used as soon as possible.
· Please avoid rapid transitions in ambient temperature, especially, in high humidity environments where
condensation can occur.
(3) Static Electricity
· Static electricity or surge voltage damages the BG-LEDs.
It is recommended that a wrist band or an anti-electrostatic glove be used when handling the BG-LEDs.
· All devices, equipment and machinery must be properly grounded. It is recommended that measures
be taken against surge voltage to the equipment that mounts the BG-LEDs.
· When inspecting the final products in which BG-LEDs were assembled, it is recommended to check
whether the assembled BG-LEDs are damaged by static electricity or not. It is easy to find
static-damaged BG-LEDs by a light-on test or a VF
test at a lower current (below 1mA is recommended).
· Damaged BG-LEDs will show some unusual characteristics such as the leak current remarkably
increases, the forward voltage becomes lower, or the BG-LEDs do not light at the low current.
