lite-on technology corporation p r o p e r t y o f l i t e - o n o n l y part no. : ltw-C230DS2 page : 8 of 11 bns-od-c131/a4 cautions 1. application the leds described here are intended to be used for ordinary electronic equipment (such as office equipment, communication equipment and household applications).consult liteons 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 life or health (such as in aviation, transportation, traffic control equipment, medical and life support systems and safety devices). 2. storage the package is sealed: the leds should be stored at 30c or less and 90%rh or less. and the leds are limited to use within one year, while the leds is packed in moisture-proof package with the desiccants inside. the package is opened: the storage ambient for the leds should not exceed 30c temperature or 60% relative humidity. it is recommended that leds out of their original packaging are ir-reflowed within 672hrs. 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 more than one week should be baked at about 60 deg c for at least 20 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: r eflow soldering soldering iron pre-heat pre-heat time peak temperature soldering time 150~200c 120 sec. max. 260c max. 10 sec. max.(max. two times) temperature soldering time 300c max. 3 sec. max. (one time only) soldering notes: because different board designs use different number and types of devices, solder pastes, reflow ovens, and circuit boards, no single temperature profile works for all possible combinations. however, you can successfully mount your packages to the pcb by following the proper guidelines and pcb-specific characterization. lite-on runs both component-level verification using in-house kyramx98 reflow chambers and board-level assembly. the results of this testing are verified through post-reflow reliability testing. profiles used at lite- on are based on jedec standards to ensure that all packages can be successfully and reliably surface mounted. figure on page3 shows a sample temperature profile compliant to jedec standards. you can use this example as a generic target to set up your reflow process. you should adhere to the jedec profile limits as well as specifications and recommendations from the solder paste manufacturer to avoid damaging the device and create a reliable solder joint. a ll data sheet.com
lite-on technology corporation p r o p e r t y o f l i t e - o n o n l y 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 curren t 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: u se of a conductive wrist band or anti-electrostatic glove when handling these leds. a ll devices, equipment, and machinery must be properly grounded. w ork tables, storage racks, etc. should be properly grounded. u se ion blower to neutralize the static charge which might have built up on surface of the leds plastic lens as a result of friction between leds during storage and handling. 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. part no. : ltw-C230DS2 page : 9 of 11 bns-od-c131/a4 a ll data sheet.com
