(2) Avoid any contact by a sharp metal nail or other materials with the encupsulant.

(3) Pick and Place

Recommend condition : nozzle inner radius

≧

φ4.4mm

Avoid direct contact to the encapsulant with the nozzle.

(4). PCB handling

Bending the circuit board with soldered LEDs may cause breakage of LEDs.

Please take care to bow, twist, and warpage of fthe PCB.

2. Lighting at low current

A minimum current value of lighting of all dice is 6mA.

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.

3. Handling of static electricity

These products are sensitive to static electricity charge.

Please take measure to prevent any static electricity being produced as the wearing of a wristband

or anti-static gloves when handling this product.

All devices, equipment, and machinary 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.
