(4). PCB handling
Bending the circuit board with soldered LEDs may cause breakage of LEDs.
Please take care to bow, twist, and warpage the PCB.

9-2. Lighting at a low current
A minimum current value of lighting of all dice is 30mA.
When a minimal current is applied, LED dice may look different in their brightness due to
the individual difference of the LED element, and it is not a failed product.
9-3. Handling of static electricity
- These products are sensitive to static electricity charge.
Please take measures to prevent any static electricity being produced such as the wearing of a
wristband or anti-static gloves when handling this product.
- All devices, equipment and machinery must be properly grounded. It is recommended that precautions
be taken against surge voltage to the equipment that mounts the LEDs.
- When inspecting the final products in which LEDs were assembled, it is recommended to check
whether the assembled LEDs are damaged by static electricity or not.
- It is easy to find static-damaged LEDs by a light-on test.
