(1) Lead Forming
● When forming leads, the leads should be bent at a point at lease 3mm from the base of the epoxy bulb.
Do not use the base of the leadframe as a fulcrum during lead forming.
● Lead forming should be done before soldering.
● Do not apply any bending stress to the base of the lead.
The stress to the base may damage the LED's characteristics or it may break the LEDs.
● When mounting the product onto a printed circuit board, the via-holes on the board should be exactly aligned
with the lead pitch of the product. If the LEDs are mounted with stress at the leads, it causes deterioration of the epoxy resin
and this will degrade the LEDs.
(2) Storage
● Shelf life of the products in unopened bag is 3 months(max.) at <30°C and 70% RH from the delivery date.
If the shelf life exceeds 3 months or more, the LEDs need to be stored in a sealed container
with silica gel desiccants to ensure their shelf life will not exceed 1 year.
● When the lead is exposed to a corrosive environment, the plated surface may tarnish which may result in a reduction
in the solderability. There is a portion of the lead under the bottom surface of the resin that is not solder-plated, this surface
may also tarnish.
● To avoid condensation, the products must not be stored in the areas where temperature and humidity fluctuate greatly.
● Do not store the LEDs in a dusty environment.
● Do not expose the LEDs to direct sunlight and/or an environment where the temperature is higher than
normal room temperature.
