1) Static electricity or surge voltage damages the LEDs.
It is recommended that a wrist band and an anti-electrostatic glove be used when handling the
LEDs.
2) All devices, equipment and machinery must be properly grounded. It is recommended that
measures be taken against surge voltage to the LED mounting equipment.
3) When inspecting the final products in which LEDs were assembled, it is recommended to
check whether the assembled LEDs are damaged by static electricity. To find static-damaged
LEDs, perform a light-on test or a VF test at a lower current (below 1mA is recommended).
4) Damaged LEDs will show some unusual characteristics such as the leakage current
remarkably increases, the forward voltage becomes lower, or the LEDs do not light at the low
current.
Criteria : ( VF>2.0V at IF=0.5mA )
LED MOUNTING METHOD
1) When mounting the LED to a housing, as shown on Fig.4, ensure that the mounting holes on
the PC board match the pitch of the leads correctly. Tolerance of dimensions of the
respective components including the LEDs should be taken into account especially when
designing the housing, PC board, etc. to prevent pitch misalignment between the leads and
holes on PCB, the diameter of the holes should be slightly larger than the size of the lead.
Alternatively, the shape of the holes could be made oval. (See Fig.4)
