Recommended Solder Pad Design
• All dimensions are in millimeters.
• Electrical isolation is required between Slug and Solder Pad.
Soldering Conditions
• When soldering High Power Led, Heat may affect the electrical and optical characteristics of the LEDs.
• In soldering, do not stress the lead frame and the resin part under the high temperature.
• The silicone part should be protected from mechanical stress or vibration until the High Power Led return to room temperature after soldering.
• Preliminary heating to be at 140˜160℃ max, for 120 seconds max.
• Soldering heat to be at 260℃ max, for 3 seconds max.
• For manual soldering is not more than 3 seconds at max 260℃, under soldering iron.
Storage
• Before opening the package, the LEDs should be kept at 30℃ or less and 70%RH or less.
• The LEDs should be used within one year.
• After opening the package, the LEDs should be kept at 30℃ or less and 30%RH or less.
• The LEDs should be used within one month after opening the package.
• If the moisture absorbent material(silicone) has fade away or the LED have exceeded the storage time, baking treatment should be performed using the following conditions. Baking treatment: 60℃±5℃ for 48 hours.
Static Electricity
• Static electricity or surge voltage damages the High Power LED. It is recommended that a wrist band or an anti-electrostatic glove be used when handing the LEDs.
• A tip soldering iron is requested to be grounded, An ionizer should also be installed where risk of static.
• All devices, equipment and machinery must be properly grounded, It is recommended that measures be taken against surge voltage to the equipment that mounts the High Power LED.
Cleaning
• Isoprophy Alcohol or Ethylene Alcohol is recommended in 5 minutes at room temperature. Do not use unspecified chemical may cause crack or haze on the surface of the epoxy resin.
• Before cleaning, a pre-test should be done to confirm whether any damage to the LED will occur.
• Freon solvent should not be used to clean the LEDs because of worldwide regulations.
Heat generation
• When the LEDs are illuminating, operating current should be decided after be considering the ambient maximum temperature.
• Please consider the heat generation of the LED when it is designed the PCB.
• The LEDs must be mounted on metal core PCB or heat sink or applied thermal pad.
Handing LED
LEDGUHON recommends the following at all times when handing LEDs or assemblies containing the these LEDs:
• When handing the LED with tools like Tweezer or Nipper, do not apply Mechanical Forces directly on LED's Surface.
• Do not touch with hand LED Lens surface directly. It may contaminate the Lens surface and affect on optical characteristics.
• LED should be handled from side because LED's molding material may be damaged with scratching on surface, piercing molding material and broking wire.
Attention: Electric Static Discharge (ESD) Protection
The symbol shown above herein to introduce "Electro-Optical-Characteristics". ESD protection for AIGaInP and InGaN is based chips is still necessary even though they are safe in low static-electic discharge. Material in AIGaInP and InGaN based chips are STATIC SENSITIVE devices. ESD protection has to considered and taken in the initial design stage. If manual work is needed, please ensure the device is well protective from ESD during all the process.
Option 1 - Tube Packing
Option 2 - Tape Reel Packing - (*Default Option*)
Notes:
1. Drawing not to scale.
2. All dimensions are in millimeters.
