13.08.2012 h2a1 - h39 5 4 / 4 soldering conditions reflow soldering: apg2c1 leds have a maximum storage temperature of 85. therefor it is not possible to use a reflow soldering process for array assembly! hot bar soldering: a hot bar soldering process is recommended when soldering apg2c1 emitters. this process will only transfer heat to the leads and avoids overheating the emitter which wil l damage the device. in order to transfer sufficient heat from the hot bar to the device, following parameters must be carefully considered: ? amount of flux ? pressing force of solder tip ? hot bar temperature for the standard assembly process, following parame ters should be maintained: ? hot bar temperature: 330 c ? force of hot bar. 40 n ? soldering time: 1.5 s it is recommended to use a copper nickel - plated hot bar mounted to standard temperature controlled soldering equipment. manual hand soldering: for prototype build or small series production runs, it is possible to place and solder the emitters by hand. it is therefor e recommended to maintain the following parameters: ? solder tip temperature 330 c ? soldering time. < 1.5 s ? junction temperature must be kept below 70 c a visual inspection may be used to check the quality of the solder joint general soldering precautions: ? mechanical stress, shock and vibration must be avoided during soldering ? only use non corrosive flux. ? do not apply current to the device until it has cooled down to room temperature after soldering.
