Precautions in use (1) Soldering Conditions 1) When soldering, leave minimum clearance between the resin and the soldering point. 2) Maximum allowable soldering conditions Soldering dipping : 260 degrees C max., 10 seconds max., 2 time. Soldering iron : 350 degrees C max., 3 seconds max., 1 time, power 40w max. 3) Contact between molten solder and the resin must be avoided. 4) Correction the soldered position after soldering must be avoided. 5) In soldering, do not apply any stress to the lead frame, particularly when heated. 6) When other SMD parts on the same circuit board and adhesive is to be cured, maximum allowable conditions are : 120 degrees C max., 60 seconds max. (2) Lead forming and cut 1) 2) 3) 4) Lead forming must be done below the tie bar cutting portion. When forming a lead, do not stress the resin case. Lead forming must be done before soldering. Cutting the lead frame at high temperature may result in personal injury. Cut the lead frame at room temperature. (3) Assembly 1) Do not apply any stress to the lead frame while assembling. 2) When mounting products onto PCBs, the pitch between the mounting holes must match the pitch of the LEDs. (4) Static Electricity 1) These products are sensitive, a high standard of care must be used. Particularly if an overcurrent and over-voltage which exceeds the Absolute Maximum Rating of Products is applied, the overflow in energy may cause damage to, or possibly result in destruction of, the Products. Customer shall take absolutely secure countermeasures against static electricity and surge when handling Products. 2) A protection device should be installed in the LED driving circuit, which dose not exceed the max. rating for surge current during on/off switching. 3) Proper grounding of Products, use of conductive mat, semiconductive working uniform and shoes, and semiconductive containers are considered to be effective as countermeasures against static electricity and surge. 4) A soldering iron with a grounded tip is recommended. An ionizer should also be installed where risk of static generation is high. (5) Safety Precautions 1) Users must comply with the laws and public regulations concerning safety. The light output of the products may cause injuries to human eyes in circumstances where the products are viewed directly with unshielded eyes for more than a few seconds.
