5 CAUTIONS
・ When forming leads, the leads should be bent at a point at last 3 mm from the base of the
・ 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
・ When mounting the LEDs onto a printed circuit board, the holes on the circuit board should
・ Store at room temperature (25±3℃) and under low humidity (RH lower than 50%).
・ Static electricity or surge voltage damages the LEDs. It is recommended to use a wrist band
・ Hand soldering should be performed at temperatures under 300℃ and less than 3 seconds.
・ Reflow soldering should be performed at the peak temperature under 240℃ and less than 10
