eye-response curve.
• When soldering, leave 2mm of minimum clearance from the resin to the soldering point.
• Dipping the resin to solder must be avoided.
• Correcting the soldered position after soldering must be avoided.
• In soldering, do not apply any stress to the lead frame particularly when heated.
• Lead forming must be done before soldering.
• It is necessary to cut the lead frame at normal temperature.
Static Electricity and surge damages the LED. It is recommend to use a wrist band or
anti-electrostatic glove when handling the LED. All devices, equipment and machinery
must be properly grounded.
