Therefore, it is a weak structure against the external stress. Please take care that the external stress is not added to the product. ②The voltage must be applied to LED only as a forward direction.Moreover,please design circuit diagram considering no voltage gap between Anode and Cathode during off state. If the reverse voltage is applied to LED for a long term, the electro-migration is generated and there is a possibility of the short-circuit of the circuit. ③This product is sensitive for electrostatic voltage and suge voltage. Static electrocity or surge voltage can deteriorate product and its reliability. Please make sure that all devices and equipments must be grounded. We recommend to built in zener diode or TVS(Transient Voltage Suppression)as protection circuit against static electricity. ④This product is composed of blue LED chip and special phosphor. Color tone is possible to vary in some degree,depending on the operating conditions such as ambient temperature or current amount. Also it is So please verify the performance before use. ⑤Do not look directly at LEDs with unshielded eyes, or damage to your eyes may result. ⑥Materials with high thermal conductivity are used in this product in order to allow generated heat to escape effectively out of the product. Avoid locating other heat sources(ex.resistance, etc.)near the products on circuit board to protect the devices from the heatedamage. Please make sure thatcasa temperture is always under 85℃ during operation, include the self-heat. ⑦Since dust on the surface of the radiation part is hard to remove and may decrease the luminous intensity, please handle the products in a clean, non-dusty condition. ⑧The luminous area of this product is formed with silicone resin. In the case of handling this device, please do not push the luminous area by the sharp tools. The crack and peel off of the emitting area, and the wire deformation are generated and it causes not lighting. It pressurizes by the head of the width of the point 1mm referring and the load where not lighting is generated is as follows. SIDE : 5N TOP : 40N 15 sharp LD-E14-1-15-A Model No. GM5Fxxxx10A “Contents in this technical document be changed without any notice due to the product modification.” http://www.sharp-world.com/products/device/ ⑨This product is the small size and the luminous area portion is formed by silicone resin, there is a possibility to have a damage by the external stress. ・ In the case of the handling with the tweezers In the case of the handling with the tweezers, please pick up the products with the sides of the case and do not touch the luminous area. ・ In the case of the mount of the product Please use this product after confirming the mouting condition, because there is a possibility to have a damage by the external stress when the load is applied by the nozzle of the mouter.. ⑩Please make sure not to apply any external stress to resin after mounted as well. When the substrate bends after mounted, the product might be applied by an external stress, and the crack will be generated in the soldering part. Please arrange the product in the direction not stressed for the warp of the substrate after mounted. ⑪Please do not pile the substrate after this product is mounted. This product will be damaged by the substrate, and it causes the crack of the lens and not lighting by the inner-wire deformation or wiring disconnection. ⑫The products are not designed for the use under any of the following conditions. Please verify their performance and reliability well enough if you use under any of the following conditions; (1)In a place with a lot of moisture, dew condensation, briny air, and corrosive gas (Cl,H2S,NH3,SO2,NOX,etc) (2)Under the direct sunlight, outdoor exposure, and in a dusty place (3)In water, oil, medical fluid, and organic solvents ⑬The silicone resin using for LED device is affected for strong acid, strong alkalinity. Under influence by heat or the light from LED device, halogen gas is generated from neighboring materials and may adversely affect LEDs. Please use that you do not have any problem enough after confirmation. ⑭Guarantee covers the compliance to the quality standards mentioned in the Specifications; however it does not cover the compatibility with application in the end-use, including assembly and usage environment. In case any quality problems occurred in the application of end-use, details will be separately discussed and determined between the parties hereto. 16 sharp LD-E14-1-15-A Model No. GM5Fxxxx10A http://www.sharp-world.com/products/device/ “Contents in this technical document be changed without any notice due to the product modification.” 7-2. Soldering This product is reflow ready model(within 2 itemes), but it not ready for solder dipping. 7-2-1. Reflow ①Package temperature at reflow soldering is defined in the Fig. below. However, even when it is under the profile condition, external stress can damage the internal packages. Please test your reflow method and verify the solderability before use. ②Giving the soldering process promptly after opened aluminum package is recommended. Soldering process must be completed including 2nd reflow as repairing within 3days (Temperature:5℃ to 30℃ Relative humidity:60% or less) after opend. (Storage in a dry box after the first reflow is recommended.) Temperature [℃] ③Recommended Temperature Profile 4℃/sec.Max. 4℃/sec.Max. 260℃ Max. 220℃ 160 ~ 180℃ 60 ∼ 70[s] 140 [s] Time [sec] Since the thermal conduction to the products depends on the specification of the reflow machine, and the size and layout of the PCBs please test your solder conditions carefully. Moreover, after the reflow process, If the activator remains in the flux between anode and cathode, the remaining activator might react during high temperature operation, and the electro-migration is generated and there will be a possibility of a short-circuit. Please use it after confirming the electro-migration is not generated while mounted actual 17 sharp LD-E14-1-15-A Model No. GM5Fxxxx10A “Contents in this technical document be changed without any notice due to the product modification.” http://www.sharp-world.com/products/device/ ④Recommended metal mask design Solderability depends on the reflow conditions, solder past, and materials of the PCBs etc. Please test and verify the solderability under the actual solder method. Moreover, it might have a risk of short-circuit(leakage)with the electro-migration by the remining activator in the flux. Please make a suitable section and test of the metal mask in terms of pitch size and thickness before mass production. 2.3 2.3 0.3 0.3 0.67 1.2 Center 0.4 0.6 1.3 Recommend metal mask design 2.13 Cathode ⑤Precautions for PCB backside dip process Please verify your conditions carefully in giving the dip process on the backside of the PCBs, since the warped boards caused by heat and heat itself affect the inside of the package. It is recommended to give the reflow process after dip process. Though it is also available to give the reflow process before the dip process, the interval of the two processes should be as short as possible. 7-3.Cleaning ・ Avoid cleaning the PCBs, since packages and resin are eroded by cleaning. Please use the soldering paste without need of cleaning. ・ Avoid ultrasonic cleaning 18 sharp LD-E14-1-15-A http://www.sharp-world.com/products/device/
