design considerations while operating at i f <1.0ma, ctr variation may increase. please make design considering this fact. this product is not designed against irradiation and incorporates non-coherent ired. degradation in general, the emission of the ired used in photocouplers will degrade over time. in the case of long term operation, please take the general ired degradation (50% degradation over 5years) into the design consideration. ? for additional design assistance, please review our corresponding optoelectronic application notes. 9 design guide PC844X series sheet no.: d2-a03602en
manufacturing guidelines soldering method flow soldering : due to sharp's double transfer mold construction submersion in flow solder bath is allowed under the below listed guidelines. flow soldering should be completed below 270?c and within 10s. preheating is within the bounds of 100 to 150?c and 30 to 80s. please don't solder more than twice. hand soldering hand soldering should be completed within 3s when the point of solder iron is below 400?c. please don't solder more than twice. other notices please test the soldering method in actual condition and make sure the soldering works fine, since the impact on the junction between the device and pcb varies depending on the tooling and soldering conditions. 10 PC844X series solvent cleaning: solvent temperature should be 45?c or below immersion time should be 3minutes or less ultrasonic cleaning: the impact on the device varies depending on the size of the cleaning bath, ultrasonic output, cleaning time, size of pcb and mounting method of the device. therefore, please make sure the device withstands the ultrasonic cleaning in actual conditions in advance of mass production. recommended solvent materials: ethyl alcohol, methyl alcohol and isopropyl alcohol in case the other type of solvent materials are intended to be used, please make sure they work fine in ac- tual using conditions since some materials may erode the packaging resin. cleaning instructions this product shall not contain the following materials. and they are not used in the production process for this device. regulation substances:cfcs, halon, carbon tetrachloride, 1.1.1-trichloroethane (methylchloroform) specific brominated flame retardants such as the pbbos and pbbs are not used in this product at all. presence of odc sheet no.: d2-a03602en
sleeve package package materials sleeve : hips (with anti-static material) stopper : styrene-elastomer package method max. 25pcs of products shall be packaged in a sleeve. both ends shall be closed by tabbed and tabless stoppers. the product shall be arranged in the sleeve with its primary side mark on the tabless stopper side. max. 20 sleeves in one case. sleeve outline dimensions through-hole package specification 11 12.0 6.7 5.8 10.8 520 2 PC844X series (unit : mm) sheet no.: d2-a03602en
