CAUTION - The ‘‘accelerated equivalent’’ soak requirements shall not be used until correlation of damage response, including electrical, after soak and reflow is established with the ‘‘standard’’ soak requirements or if the known activation energy for diffusion is 0.4 - 0.48 eV. Accelerated soak times may vary due to material properties, e.g., mold compound, encapsulant, etc. JEDEC document JESD22-A120 provides a method for determining the diffusion coefficient. 2. The standard soak time includes a default value of 24 hours for semiconductor manufacturer’s exposure time (MET) between bake and bag and includes the maximum time allowed out of the bag at the distributor’s facility. If the actual MET is less than 24 hours the soak time may be reduced. For soak conditions of 30 °C/60% RH the soak time is reduced by one hour For each hour the MET is less than 24 hours. For soak conditions of 60 °C/60% RH, the soak time is reduced by one hour for each five hours the MET is less than 24 hours. If the actual MET is greater than 24 hours the soak time must be increased. If soak conditions are 30 °C/60% RH, the soak time is increased one Hour for each hour that the actual MET exceeds 24 hours. If soak conditions are 60 °C/60% RH, the soak time is increased one hour for each five Hours that the actual MET exceeds 24 hours. 3. Supplier may extend the soak times at their own risk. ESD Protection During Production Electric static discharge can result when static-sensitive products come in contact with the operator or other conductors. The following procedures may decrease the possibility of ESD damage: 1.Minimize friction between the product and surroundings to avoid static buildup. 2.All production machinery and test instruments must be electrically grounded. 3.Operators must wear anti-static bracelets. 4.Wear anti-static suit when entering work areas with conductive machinery. 5.Set up ESD protection areas using grounded metal plating for component handling. 6.All workstations that handle IC and ESD-sensitive components must maintain an electrostatic potential of 150V or less. 7.Maintain a humidity level of 50% or higher in production areas. 8.Use anti-static packaging for transport and storage. 9.All anti-static equipment and procedures should be periodically inspected and evaluated for proper functionality. Heat Generation: 1.Thermal design of the end product is of paramount importance. Please consider the heat generation of the LED when making the system design. The coefficient of temperature increase per input electric power is affected by the thermal resistance of the circuit board and density of LED placement on the board ,as well as other components. It is necessary to avoid intense heat generation and operate within the maximum ratings given in this specification. 2.Please determine the operating current with consideration of the ambient temperature local to the LED and refer to the plot of Permissible Forward current vs. Ambient temperature on CHARACTERISTICS in this specification. Please also take meas ures to remove heat from the area near the LED to improve the operational characteristics on the LED. 3.The equation ① indicates correlation between Tj and Ta ,and the equation ② indicates correlation between Tj and Ts Tj = Ta + Rthj-a *W ……… ① Tj = Ts + Rthj-s *W ……… ② Tj = dice junction temperature: °C Ta = ambient temperature:°C Ts = solder point temperature:°C Rthj-a = heat resistance from dice junction temperature to ambient temperature : °C/ W Rthj-s = heat resistance from dice junction temperature to Ts measuring point : °C/ W W = inputting power (IFx VF) : W SPEC NO: DSAJ0164 REV NO: V.3 DATE: APR/01/2009 PAGE: 7 OF 10 APPROVED: WYNEC CHECKED: Allen Liu DRAWN: S.P.Chen ERP: 1212000060 3.0x2.0mm SMD LED WITH CERAMIC SUBSTRATE Handling Precautions Compare to epoxy encapsulant that is hard and brittle, silicone is softer and flexible. Although its characteristic significantly reduces thermal stress, it is more susceptible to damage by external mechanical force. As a result, special handling precautions need to be observed during assembly using silicone encapsulated LED products. Failure to comply might leads to damage and premature failure of the LED. 1. Handle the component along the side surfaces by using forceps or appropriate tools. 2. Do not directly touch or handle the silicone lens surface. It may damage the internal circuitry. 3. Do not stack together assembled PCBs containing exposed LEDs. Impact may scratch the silicone lens or damage the internal circuitry. 4. The outer diameter of the SMD pickup nozzle should not exceed the size of the LED to prevent air leaks. The inner diameter of the nozzle should be as large as possible. 5. A pliable material is suggested for the nozzle tip to avoid scratching or damaging the LED surface during pickup. 6. The dimensions of the component must be accurately programmed in the pick-and-place machine to insure precise pickup and avoid damage during production.

Refer to the following recommended position and direction of LED. Appropriate LED mounting is to place perpendicularly against the stress affected side. 2.Depending on the position and direction of LED,the mechanical stress on the LED package can be changed. Refer to the following figure. 3.Do not split board by hand.Split with exclusive special tool. 4.If an aluminum circuit board is used,a large stress by thermal shock might cause a solder crack. For this reason,it is recommended an appropriate verification should be taken before use.
