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. ② This product is sensitive for electrostatic voltageand surge voltage.Static electricity 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 protectioncircuit against static electricity. ③ This product is composed of blue LED chip and special phosphor. Color tone is possibleto vary in some degree, depending on the operating conditions such as ambient temperature or current amount. Also it is subject to variation due to the afterglow of the phosphor in pulse drive. So please verify the performancebefore use. ④ Do not look directly at LEDs with unshielded eyes, or damage to your eyes may result. ⑤ Materials 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 heatdamage. Please make sure that case temperature is always under 100 ℃ during operation, including the self-heating. ⑥ Since 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. ⑦ The lensof this product is formed with silicone resin. In the case of handling this device, please do not push the lens portion by the sharp tools. The crackandpeeloffof the lens, and the wire deformation are generated and it causes not lighting. ・ Especially do not apply the load from horizontal direction to the side of the lens of this product. ・ Please do not apply the static loadof 2.5N or more (1.4mmφor less)fromthe diagonal 45 degrees of this productslens portion to the direction of an optical axis. ⑧ This product is the small size andthe lens portion is formed by silicone resin, there isa possibilityto have damage by the external stress. 17 sharp LD-E7-7-14-A Model No. GM2BB**GT4E Contents in this technical document be changed without any notice due to the product modification. http://www.sharp-world.com/products/device/ ・ In the case of the handling withthe tweezers In the case of the handling with the tweezers, please pick up the products with the sides of the ceramic substrate and do not touch the lens portion . ・ In the case of the mount of the product Please use this productafter confirming the mounting condition, 1.2mm 1.66mm because there is a possibility to have damage by the external stress when the load is applied by the collet of the mounter. Please see the recommended collet of this product as right picture. 2.6mm 3.2mm ⑨ Please 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 thecrack will be generated in the soldering part. Please arrange the product in the direction not stressed for thewarp of the substrate after mounted. ⑩ Please do not pile the substrate after this product is mounted.This product will be damaged by the substrate, and it causes the crack ofthe lens and not lighting bythe inner-wire deformation or wiringdisconnection. ⑪ The 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 ⑫ Guarantee 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. 18 sharp LD-E7-7-14-A Model No. GM2BB**GT4E Contents in this technical document be changed without any notice due to the product modification. http://www.sharp-world.com/products/device/ 7-2 Soldering This product is reflow ready model (within 2 times), but it is not ready for solder dipping. Reflow ① Package 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. ② Giving the soldering process promptly after opened aluminum package is recommended. Soldering process must be completed including 2ndreflow as repairing within 7 days (Temperature: 5 ℃ to 30 ℃ Relative humidity: 60% or less) after opened. (Storage in a dry box after the first reflow is recommended.) ③ Recommended solder paste Solder paste : M705-221BM5-42-11(SENJU METAL INDUSTRY CO., LTD) Temperature [℃] ④ Recommended Temperature Profile 260( MAX) 1 to 4℃/s 220 200 150 1 to 2.5℃/s 60s (MAX) 60 to 120s 5s (MAX) 1 to 4℃/s 25 Time [second] In order to secure the product reliability, it is recommended to control the peak temperature and temperature gradient. Moreover, 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. 19 sharp LD-E7-7-14-A Model No. GM2BB**GT4E Contents in this technical document be changed without any notice due to the product modification. http://www.sharp-world.com/products/device/ ⑤ Recommended solder pad design We recommend the metal mask of thickness 0.15mm for screen-printing. Solderability depends on the reflow conditions, solder paste, 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 remaining activator in the flux. Please make a suitable selection and test of the metal mask in terms of pitch size and thickness before mass production. 2.8 3.2 1.2 0.8 1.2 0.4 1.15 0.5 0.25 0.5 （Unit：mm） ⑥ Precautions 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. 20 sharp LD-E7-7-14-A http://www.sharp-world.com/products/device/
