After soldering the LEDs should be protected from mechanical shock or vibration until the LEDs return to room temperature. When it is necessary to clamp the LEDs to prevent soldering failure, it is important to minimize the mechanical stress on the LEDs. Temperature Profile PCB Footprint Layout (Unit: mm) Static Electricity • LEDs are very sensitive to Static Electricity and surge voltage. It is recommended to always wear a wrist band or an anti-electrostatic glove when handling the LEDs. • All devices, equipment and machinery must be grounded properly. It is recommended that precautions should be taken against surge voltage to the equipment that mounts the LEDs. 16.06.2011 SMT405R 4 of 4
