Generally, semiconductor products are susceptible to malfunction by influences of environment. Follow the following instructions when using Seiko NPC's products.
| - |
Ground the operator, jig, operation table, and equipment. Do not apply static electricity to the product. |
| - |
Do not contact a charged object or keep it away from the product. |
| - |
Use an ionizer at processes and equipment that generate static electricity. |
| - |
o not exceed the absolute maximum ratings. |
| - |
Lower the thermal stress and temperature stress imposed on the product as much as possible. |
| - |
Do not insert the product in the reverse direction. |
| - |
Avoid application of a surge voltage to the product from the tester during measurement. |
| - |
Store the product at a location where temperature is 5 to 30°C and relative humidity is 40 to 60%. |
| - |
Avoid storing the product at a location subject to abrupt temperature change and condensation. |
| - |
Avoid storing the product at a location where subject to corrosive gas and dust. |
| - |
Store the product in a container that is difficult to charge. |
| - |
Do not apply any pressure to the product while it is stored. |
| 3.1 Product in water vapor-proof package |
| - |
Use the product within the indicated storage limit. |
| - |
Use the product within 2 weeks after opening the water vapor-proof package. |
| - |
When reflowing the product for the second time, do so within 2 weeks after the first reflow. |
| - |
After the above limit have expired, bake the product at 125°C for 24 hours, and check its solderability before using it. |
3.2 Product not in water vapor-proof package |
| - |
The limit period of storing the product is 1 year as the lead may be rusted. |
| - |
After 1 year, check the solderability and rust on the lead of the product before using it. |
| 4. Notes on packaging container |
| - |
Usually, trays, sticks, and embossed tapes are not mechanically durable nor do they have a resistance to heat. To bake the product, move it to other heat-resistive container. |
| - |
When moving the product to another container, be careful not to damage its lead. |
| - |
If the container is heat-resistive, it has inscription such as "HEAT PROOF" or "135°C" on it. |
| 5. Mounting temperature profile |
| Plastic package products may malfunction if they are subjected to abrupt temperature change during the mounting process. Seiko NPC recommends the following temperature profile when mounting. |
