Design Advantage:

• Pure copper leadframe.
• Standard A Class chips.
• Cost performance.
• Gold wire bond.
• Easy reflow sodering.

Cautions 1w high power led chip, 3w high power led chip

1) Soldering Conditions

Number of reflow process shall be less than 2 times and cooling process to normal temperature is required between first and Second soldering process.

2) Static Electricity

It is recommended that a wrist band or an anti-electrostatic glove be used when handling the LEDs.All devices, equipment and machinery must be properly grounded.Damaged LEDs will show some unusual characteristics such as the forward voltage becomes lower, or the LEDs do not light at the low current. Criteria : (VF > 2.0V at IF=0.5mA)

3) Storage

Before opening the package ,The LEDs should be kept at 30°C or less and 70%RH or less. The LEDs should be used within a year.

4) Moisture Proof Package
