Shipping, Handling and Storage
| Item | Requirement |
|---|---|
| Shipping | One shipping option is offered as standard: un-sawn wafer. Sampling CP test is performed in order to guarantee minimum yield. |
| Handling | Product must be handled only at ESD safe workstations. Standard ESD precautions and safe work environments are as defined in MIL-HDBK-263. Product must be handled only in a class 10,000 or better-designated clean room environment. |
| Wafer Storage | Proper storage conditions are necessary to prevent product contamination and/or degradation after shipment. Un-sawn wafers and singulated die can be stored for up to 12 months when in the original sealed packaging at room temperature (45% ± 15% RH controlled environment). Un-sawn wafers and singulated die that have been opened can be stored when returned to their containers and placed in a nitrogen purged cabinet, at room temperature (45% ± 15% RH controlled environment). Sawn wafers on a film frame are intended for immediate use and have a limited shelf life. |
Notes
- Electrical characteristics are referenced to the die assembled in a TSSOP-8 package. Bonding wire reference: Gate — Cu 1.65 mil × 2; Source — Cu 1.65 mil × 6 × 2.
- (CP) Parameter verified by sampling chip-probe (wafer sort) test.
- To reduce the risk of contamination or degradation, it is recommended that product not being used in the assembly process be returned to its original container and resealed with a vacuum seal process.
