(2) when the customer is considering to use the products in special applications, such as transportation systems (automobiles, tra ins, vessels), medical equipments, aerospace, nuc lear power control, and submarine repeater s or systems, please contact mitsubishi electric or an authorized distributor. 2. shipping conditions: (1) during shipment, place the packing boxes in the correct directi on, and fix them firmly to keep them immovable. placing the box es upside down, tilting, or applying abnormal pressure onto them ma y cause deformation in the elec trode terminals, breaking of opt ical fiber, or other problems. (2) never throw or drop the packing boxes. hard impac t on the boxes may cause break of the devices. (3) take strict precautions to keep the dev ices dry when shipping under rain or snow. 3. storage conditions: when storing the products, it is recommended to store them fo llowing the conditions described below without opening the packing . not taking enough care in storing may result in defects in electric al characteristics, solderi ng quality, visual appearance, and so on. the main points are described below (if special storage conditions are given to the product in the specification sheet, they have p riority over the following general cautions): (1) appropriate temperature and humidity condi tions, i.e., temperature range between 5~30 c, and humidity between 40~60 percent rh, should be maintained in storage locations. controlling the te mperature and humidity within this range is particularly impor tant in case of long-term storage for six months or more. (2) the atmosphere should be particula rly free from toxic gases and dust. (3) do not apply any load on the product. (4) do not cut or bend the leads of the devices which are to be stor ed. this is to prevent corrosion in the cut or bent part of th e lead causing soldering problems in the customer?s assembling process. (5) sudden change in temperature may cause condens ation in the product or packing, therefor e, such locations should be avoided for storing. temperature in storage locations should be stable. (6) when storing ceramic package products for ex tended periods of time, the leads may turn reddish due to reaction with sulfur in the atmosphere. (7) storage conditions for bare chip and uns ealed products shall be stated separatel y because bare chip and unsealed products require stricter controls than package sealed products. 4. design conditions and environment under use: (1) avoid use in locations where water or organic solvents adhere di rectly to the product, or where there is any possibility of th e generation of corrosive gas, explosive gas , dust, salinity, or other troublesome c onditions. such environments will not only si gnificantly lower the reliability, but also may lead to serious accidents. (2) operation in excess of the absolute maximum ratings can c ause permanent damage to the device. the customers are requested to design not to exceed those ratings even for a short time. 5. esd safety cautions: the optoelectronic devices are sens itive to static electricity (esd, electro-static discharge) . the product can be broken by es d. when handling this product, please observe the following countermeasures: to prevent break of devices by static el ectricity or surge, please adopt the following countermeasures in the assembly line: (1) ground all equipments, machinery jigs, and tools in the process li ne with earth wires installed in them. take particular care with hot plates, solder irons and other items for which t he commercial power supplies are prone to leakage. (2) workers should always use earth bands. us e of antistatic clothing, electric conduc tive shoes, and other safety equipment while at work is highly recommended. (3) use conductive materials for this product?s container, etc. (4) it is recommended that grounding mats be pl aced on the surfaces of assembly line workbench and the surrounding floor in work area, etc. (5) when mounting this product in parts or materials which can be electrically char ged (printed wiring boards , plastic products, e tc.), pay close attention to the static electric ity in those parts. esd may damage the product. (6) humidity in working environment should be controlled to be 40 percent rh or higher. these countermeasures are most general, and there is a need to carefully confirm t he line before starting mass production using this product (in the trial production, etc.). it is extremely important to prevent surge, e liminate it rapidly, and prevent it from spreading.
