IC packaging stamping dies can be integrated with automatic feeding and downstream processes, and are suitable for production modes such as progressive, transfer, or compound dies.
Main features and applicable scope of IC packaging stamping dies
- High-precision forming: Precise guidance, clearance control, and springback compensation ensure repeatability and stable tolerances for critical dimensions in blanking, piercing, and bending.
- Wear resistance and long life: Key components use high-wear-resistant die steels combined with heat treatment and surface reinforcement (such as nitriding or PVD coatings) to reduce wear and sticking.
- High-speed stable capacity: Die structure is optimized in coordination with feeding systems and presses to accommodate high-cycle production and reduce downtime or defect rates.
- Applicable parts: Commonly used for blanking and forming of leadframes, terminals/pins, heat sinks, and other metal supports for packaging.
- Die types: Options include progressive dies, transfer dies, or compound dies, selected according to part complexity and production volume requirements.
Materials, design, and service points for IC packaging stamping dies
- Materials and heat treatment: Common die steels include SKD11 and H13; quenching and tempering processes are applied according to part characteristics to ensure strength and toughness.
- Surface reinforcement and lubrication compatibility: Apply nitriding, carbo-nitriding, or PVD coatings to cavities, punches, and guide components, and ensure coatings are compatible with production lubricants to prevent delamination.
- Process control key points: Precisely control blanking clearance and edge chamfers, design springback compensation and sufficient rigidity, optimize chip removal and ejection structures, and implement temperature control or cooling measures to maintain dimensional stability.
- Quality and service: Provide die design review, sample tryout, and production validation; perform strict dimensional inspection before delivery and offer on-site setup support and subsequent maintenance recommendations to help customers quickly achieve stable mass production.
