Storage

Recommended storage environment

Temperature: 5oC ~ 30oC (41oF ~ 86oF)

Humidity: 60% RH Max.

Use within 2 days after opening of sealed vapor/ESD barrier bags.

If the moisture absorbent material (silica gel) has faded away or the LEDs have exceeded the storage time, baking treatment should be performed using the following conditions.

Baking treatment : 70±5℃for 24 hours.

Fold the opened bag firmly and keep in dry environment.

[ Recommended soldering pad design ]

Use the following conditions shown in the figure.

Handling of Silicone Resin LEDs

Handling Indications

During processing, mechanical stress on the surface should be minimized as much as possible. Sharp objects of all types should not be used to pierce the sealing compound

Figure 1

In general, LEDs should only be handled from the side. By the way, this also applies to LEDs without a silicone sealant, since the surface can also become scratched.

Figure 2

When populating boards in SMT production, there are basically no restrictions regarding the form of the pick and place nozzle, except that mechanical pressure on the surface of the resin must be prevented.

This is assured by choosing a pick and place nozzle which is larger than the LED’s reflector area.
