parts inventory
**Parts Inventory Management** in semiconductor manufacturing involves maintaining optimal stock levels of spare parts, consumables, and critical equipment components.
## What Is Parts Inventory Management?
- **Scope**: Spare parts, consumables, quartz, o-rings, pumps
- **Balance**: Too much = capital tied up; too little = extended downtime
- **Systems**: MRP/ERP integration, min/max levels, reorder points
- **Strategy**: Critical spares on-site, others with fast delivery
## Why Parts Inventory Matters
A $50 o-ring out of stock can cause $100K+ production losses. Smart inventory ensures parts availability without excessive capital investment.
