90 n usage precautions (1) fixation of the optical transmission module and the optical receiving module the lock pins of each of these modules must be fixed to the printed circuit board by soldering. (2) power supply conditions please follow the conditions described in the diagram below. (3) ld module soldering (hand soldering) work and precautions 7 v must not be exceeded standard operating range vcc(5v)} sw on 5.25v 4.75v time (t) the resin molded semiconductors of this product require a degree of transparency and so additives are few and in comparison to other molded semiconductors a thermally and mechanically weak resin is used. in view of this, please refer to the following procedure and solder accordingly. soldering of the lock pins before soldering the lead pins, be sure to fix the lock pins to the printed circuit board by soldering. soldering of the lead pins observe the temperature, time, and iron capacity of table 1 for the soldering of the lead pins and solder at a point which will allow the leads to maintain at least a length of 1.6 mm from the bottom surface of the module. (see figure 1.) soldering should be done from the back side with respect to the coupling face of the module as illustrated in figure 2. after soldering please note that soon after soldering, any mounting corrections of the module or corrections of board warping that are performed will place stress on the resin mold and may destroy the resin molded semiconductor. cutting of leads the cutting of leads in a high temperature condition may cause lead breakage accidents. please cut leads at room temperature after soldering. be especially careful of the high temperature immediately after soldering. table 1 figure 1 figure 2 recommended temperature recommended time recommended iron capacity 240?c to 260?c 4 s or less 30 w to 40 w coupling face lock pin lead pin soldering iron back side of board lc module
91 (4) washing conditions depending on the solvent used in washing, the resin of the package may be penetrated. please observe the conditions described below when washing. one of the following alcohol-based solvents should be used at a solvent temperature of 45?c or less with an immersion time within 3 minutes: ethyl alcohol methyl alcohol isopropyl alcohol the adhering of dirt or dust at the time of washing could lead to a malfunction. extra care is warranted to keep the module free of dirt and dust. chloro- and freon type solvents should not be used. do not use ultrasonic cleaning. (5) short-circuiting of the output do not short-circuit the output of the optical receiving module to the power supply side or the ground side. (6) washing the ends of the optical connectors please take care not to allow the ferrule end of the optical connector to become soiled. to clean dirt from the ferrule end, moisten an industrial-type rag with alcohol and wipe away the dirt that adheres to the ferrule.
