As chips evolve toward higher integration and advanced processes, their complex internal structures demand greater test precision and environmental stress simulation. Primary screening has progressed from basic functional verification to a comprehensive evaluation system covering electrical performance, environmental adaptability, and long-term stability.
Power IC Screening: Multidimensional Validation
Power ICs serve as the "energy hub" of electronic devices. Their stability directly impacts critical end products (e.g., new energy vehicles, industrial control systems). Primary screening requires 7 key test categories to build a complete validation chain.
