Keep the factory ambient conditions at < 30deg-C/60％％％％RH . 3. Store the components in an environment of < 25±5deg-C/10%RH after the bag is opened. (The condition is also applied to a stay in the manufacture process). (2) Conditions for handling of products Make sure all of the moisture barrier bags have no holes, cracks or damages at receiving. If an abnormality is found on the bag, its moisture level must be checked in accordance with 2 in (2). Refer to the label on the bag. 1.All of the surface mounting process (reflow process) must be completed in 12 months from the bag sea date. 2. Make sure humidity in the bag is less than 10%RH immediately after open, using a humidity indicator card sealed with the components. 3. All of the surface mounting process (reflow process including rework process) must be completed in 168 hours after the bag is opened (inclusive of any other processes). 4. If any conditions in (1) or condition 2 and 3 in (2) are not met, bake the components in accordance with the conditions at 125deg-C 24hours 5. As a rule, baking the components in accordance with conditions 4 in (2) shall be once. 6. Since semi-conductors are inside of the components, they must be free from static electricity while handled.(<100V) Use ESD protective floor mats, wrist straps, ESD protective footwear, air ionizers etc. , if necessary. 7. Please make sure that there are lessen mechanical vibration and shock for this mo dule, and do not drop it. TAIYO YUDEN 21/25
