asmt-txbm-nxxxx data sheet surface-mount led indicator broadcom av02-2205en 7 handling precautions the encapsulation material of the product is made of silicone for better re liability of the produc t. as silicone is a soft material; do not press on the silicone or poke a sharp object onto the s ilicone. these actions might damage the product and cause premature failure. during assembly or handling, the unit should be hel d on the body only. refer to broadcom application note an 5288 for detail information. ? do not poke sharp objects int o the silicone encapsulant. sharp objects, such as tweezers or syringes, might apply excessive force or e ven pierce through the silicone and induce failures to the led die or wire bond. ? do not touch th e silicone encapsul ant. uncontrolled force acting on the silicone encapsulant might result in excessive stress on the wir e bond. hold the led only by the body. ? do not stack assembled pcbs together. use an appropriate rack to hold the pcbs. ? the surface of the silicone material attracts dusk and dirt easier than epoxy due to its surface tackiness. to remove foreign particles on t he surface of silicone, use a cotton bud with isopropyl alcohol (ipa). during cleaning, rub the surface ge ntly without putting much pressure on th e silicone. ultrasoni c cleaning is not recommended. moisture sensitivity this product is qualified as moisture sensitive level 2a per jedec j-std-020. precaut ions when handling this moisture-sensitive product a re important to ensure the reliability of the product. ref er to broadcom application note an5305, handling of moisture sensitive surface mount devices , for details. ? storage before use C unopen moisture barrier bag (mbb) can be stored at < 40c / 90% rh for 12 months. if the actual shelf life has exceeded 12 mo nths and the humidity indicator card (hic) indic ates that baking is not required, it is safe to reflow the leds per the original msl rating. C it is not recommended to open the mbb prior to assembly (for ex ampel, for iqc). ? control after opening the mbb C read the hic immediatel y upon opening the mbb. C keep the leds at <30c / 60% rh at all times and all high temperature-related processes, including soldering, curing, or rework, muste completed within 672 hours. ? control for unfinished reel store any unused leds in a sealed mbb with desiccant or desiccator at < 5% rh. ? control of assembled boards if the pcb soldered with leds is to be subjected to other high-temperature processes, the pcb must be stored in a sealed mbb with desiccant or desiccator at < 5% rh to ensure no leds have exceeded their floor life of 672 hours. ? baking is required if: C the hic is not green at 10% and is azure at 5% C the leds are exposed to c ondition of > 30c / 60% rh at any time. C the leds floor life exceeded 672 hours. recommended baking condit ion: 60c 5oc for 20 hours. application precautions ? the drive current of the led must not exceed the maximum allowable limit across temperature as stated in the data sheet . constant current driving is recommended to ensure consistent performance. ? leds exhibit slightly different characteristics at different drive currents that might result in larger variations in their performance (that is , intensity, wavelength, and forward voltage). set the application current as close as possible to the test current t o minimize these variations. ? the led is not intended fo r reverse bias. use other appropriate components for such purposes. when driving the led in matrix form, it is crucial to ensure that the reverse bias voltage does not exceed the allowable limit of the led. ? do not use the led in the vicinity of material with sulfur content, in environments of high gaseous sulfur compounds and corrosive elements. examples of material that may contain sulfur are rubber gasket, rtv (room temperature vulcanizing) silico ne rubber, rubber gloves, and so on. prolonged exposure to such environments may affect the optical characteristics and product life. ? avoid rapid changes in ambien t temperature, especially in high humidity environ ments, as this will cause condensation on the led. eye safety precautions leds may pose optical hazards when in operation. it is not advisable to view directly at operating leds as it may be harmful to the eyes. for safet y reasons, use appropriate shielding or personal protective equipments.
