dry pack requirements

**Dry pack requirements** is the **set of packaging and labeling conditions required to maintain moisture-sensitive components in controlled low-humidity state** - they ensure parts remain within MSL handling limits from shipment to line use. **What Is Dry pack requirements?** - **Definition**: Includes barrier bag, desiccant quantity, humidity indicator card, and sealed labeling. - **Seal Criteria**: Bag closure quality and leak resistance are mandatory acceptance checks. - **Documentation**: MSL rating, floor-life guidance, and bake instructions must accompany each lot. - **Process Scope**: Applies at outbound packing, incoming receiving, and internal storage transfer points. **Why Dry pack requirements Matters** - **Reliability Protection**: Proper dry pack prevents moisture uptake before reflow. - **Operational Consistency**: Standardized requirements reduce interpretation errors between sites. - **Compliance**: Meeting dry-pack specs is essential for customer and standard conformity. - **Risk Mitigation**: Weak dry-pack execution leads to hidden moisture excursions. - **Cost Control**: Strong dry-pack discipline reduces bake workload and scrap exposure. **How It Is Used in Practice** - **SOP Enforcement**: Implement checklist-based pack verification before shipment release. - **Receiving Audit**: Validate seal integrity and indicator status at incoming inspection. - **Supplier Alignment**: Audit subcontractor dry-pack process capability periodically. Dry pack requirements is **the procedural foundation for moisture-safe semiconductor logistics** - dry pack requirements should be enforced as a full system of materials, labeling, and verification controls.
