(4) Soldering
Ï  Bright View LEDs use a copper alloy lead frame which provides a high thermal conductivity.
Thermal stress such as soldering heat may reduce the reliability of the product; particular
caution should be used to avoid damage prior to and during soldering.
The recommended soldering conditions are listed in the following table.
Ï  Although the recommended soldering conditions are specified in the below table, dip or
soldering at the lowest possible temperature is desirable.
Ï  When it is necessary to clamp the LEDs to prevent soldering failure, it is important to
the mechanical stress on the LEDs.
Ï  Solder the LED no closer than 1.6mm from the base of the stopper.
Ï  Dip soldering and hand solding should not be done more than one time.
Ï  A rapid-rate process is not recommended for cooling the LEDs down from the peak temperatu
Ï  Cut the LED leadframes at room temperature. Cutting the leadframes at high temperature
may cause failure of the LEDs.
