(one time one) 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 b y 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. 8 . 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 ) (a) recommended circuit (b) the brightness of each led might app ear different due to the differences in the i - v characteristics of those leds. 9 . others the appearance and specifications of the product may be modified for improvement, without prior notice. led led
