Soldering Iron

1. Temperature at tip of iron: 300 ̊C Max. (25W Max.)

2. Soldering time: 5 ± 1 sec.

Precautions For Use

1. Customer must apply resistors for protection and stability. Using Circuit B in the diagram below is recommended.

Using Circuit A can result in LED burnout.

2. Current change may lead to LED color change. If there is a large difference between the spectral color separation

current and actual service current, a color difference may occur.

3. Utilize forward current for LED operation. Subjecting the LED to continuous reverse voltage may cause damage

to the die.

Handling Precautions

1. When handling the product with tweezers, be careful to not damage the resin. The resin can be cut, chipped,

delaminated, or deformed, which can lead to wire-bond breaks.

2. Reflow soldering must not be performed more than twice. Hand soldering must not be performed more than once.

3. When soldering, do not put stress on the LEDs during heating.

4. LEDs are sensitive to static electricity or voltage surges. ESD can damage a die and its reliability.

5. Do not stack assembled PCBs together. When stacked, PCBs with soldered LEDs can damage the resin

surrounding the die, leading to failure.
