C time at maximum temperature = 20s max. ? confirm beforehand whethe r the functionality and performance of the led is affected by soldering with hot plate. ? hand soldering is not recommended. precautionary notes handling precautions the encapsulation material o f the led is made of silicone for better produc t reliability. com pared to epoxy encapsulant that is hard and br ittle, silicone is softer and flexible. observe special handling precautions during assembly of silicone encapsul ated led products. failure to comply might lead to damage and premature failure of the led. do refer to application note an5288, s ilicone encapsulation for led: advantages and handling precautions for more 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 the silicone encapsulant. uncontrolled force acting on th e silicone encapsula nt 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 at tracts dust and dirt easier than epoxy due to its surface tackiness. to remove foreign particles on the surface of silicone, use a cotton bud with isopropy l alcohol (ipa). during cleaning, rub the surface gently without putting too much pressure on the silico ne. ultrasonic cleaning is not recommended. ? for automated pick-and-place, broadcom has tested the following nozzle size t o work well with this led. however, due to the possibilit y of variations in other parameters, such as pick-and-place machine maker/ model and other settings of the machine, verify that the selected nozzle will not cause damage to the led. figure 19: nozzle size ? storage the soldering terminals of these leds are silver plated. if the leds are exposed in an ambient environment for too long, the silver plating m ight be oxidized and thus affecting its solderability performance. as such, keep unused leds in a sealed moi sture barrier bag (mbb) with desiccant or in desiccator at <5%rh. 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.

ASMG-ST00-00001 data sheet 3w tri-color high power led broadcom asmg-st00-ds100 11 ? the led is not intended fo r reverse bias. use other appropriate components f or such purposes. when driving the led in matrix form, 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 compound and corrosive elements. examples of materials that may contain s ulfur are rubber gaskets, rtv (room temperature vulc anizing) silic one rubber, rubber gloves, and so on. prolonged exposure to such environments may affect the optical characteristics and product life. ? avoid rapid changes in ambi ent temperature especially in high-humidity environments as this will cause condensation on the led. ? if the led is intended to be used in harsh or outdoor environments, protect the l ed by means of protective cover against damages caused by rain water, dust, oil, corrosive gases, external mechanical stress, and so on. thermal management optical, electrical and reliabilit y characteristics of led are affected by temperature. the junction temperature (t j ) of the led must be kept below a llowable limit at all times. t j can be calculated as follows: t j = t s + r j-s i f v fmax figure 20: thermal management to measure the soldering point temperature, a thermocouple can be mounted on the t s point as shown in the preceding figure. verify the t s of the led in the final product to ensure that the l eds are operated within all maximum ratings state d in the datasheet. eye safety and precautions leds may pose optical hazard s when in opera tion. do not look directly at operating leds as it may be harmful to the eyes. for safety reasons, use appropriate shielding or personnel protection equipment. where t s = led solder point temperature as shown in the followin g figure (c) r j-s = thermal resistance from junction to solder point (c/w) i f = forward current (a) v fmax = maximum forwa rd voltage (v)
