lite-on technology corporation property of lite-on only part no. : ltst-s110akt page : 8 of 9 bns-od-c131/a4 cautions 1. application the leds described here are intended to be used fo r ordinary electronic equipment (such as office equipment, communication equipment and household applications).consult liteon?s sales in advance for information on applications in which exceptional reliability is required, particularly when the failure or malfunction of the leds may directly jeopardize lif e or health (such as in aviation, transportation, traffic control equipment, medical and life support systems and safety devices). 2. storage the storage ambient for the leds should not exceed 30c temperature or 70% relative humidity. it is recommended that leds out of their origin al packaging are ir-reflowed within one week. for extended storage out of their original packaging, it is recommended that the leds be stored in a sealed container with appropriate desiccant, or in a desiccators with nitrogen ambient. leds stored out of their original packaging for mo re than a week should be baked at about 60 deg c for at least 24 hours before solder assembly. 3. cleaning use alcohol-based cleaning solvents such as isopropyl alcohol to clean the led if necessary. 4. soldering recommended soldering conditions: reflow soldering wave soldering soldering iron pre-heat pre-heat time peak temperature soldering time 120~150c 120 sec. max. 240c max. 10 sec. max. pre-heat pre-heat time solder wave soldering time 100c max. 60 sec. max. 260c max. 10 sec. max. temperature soldering time 300c max. 3 sec. max. (one time only) 5. drive method an led is a current-operated device. in order to ensure intensity uniformity on multiple leds connected in parallel in an application, it is recommended that a current limiting resistor be incorporated in the drive circuit, in series with each led as shown in circuit a below. circuit model a circuit model b led led (a) recommended circuit. (b) the brightness of each led might appear different due to the differences in the i-v characteristics of those leds. 6. esd (electrostatic discharge) static electricity or power surge will damage the led. suggestions to prevent esd damage: ? use of a conductive wrist band or anti-electrostatic glove when handling these leds. ? all devices, equipment, and machinery must be properly grounded. ? work tables, storage racks, etc. should be properly grounded. ? use ion blower to neutralize the static charge which might have built up on surface of the led?s plastic lens as a result of friction between leds during storage and handling.
lite-on technology corporation property of lite-on only part no. : ltst-s110akt page : 9 of 9 bns-od-c131/a4 esd-damaged leds will exhibit abnormal characteristics such as high reverse leakage current, low forward voltage, or ? no lightup ? at low currents. to verify for esd damage, check for ? lightup ? and vf of the suspect leds at low currents. the vf of ? good ? leds should be >2.0v@0.1ma for ingan product and >1.4v@0.1ma for alingap product. 7. reliability test classification test item test condition reference standard operation life ta= under room temperature as per data sheet maximum rating * test time= 1000hrs (-24hrs,+72hrs)*@20ma. mil-std-750d:1026 (1995) mil-std-883d:1005 (1991) jis c 7021:b-1 (1982) high temperature high humidity storage ir-reflow in-board, 2 times ta= 655
