The Process for Precision

Summary

Dr. Mindy Liu, a senior staff engineer at Northrop Grumman’s Advanced Technology Lab, identified inefficiencies in the chip-validation process and led a collaborative effort to create a standardized, scalable test architecture. With support from mentors, colleagues, and leadership, she transformed a year-long validation bottleneck into a more efficient, accurate, and reusable system now used by nearly 60 programs. Her story highlights how strong process, teamwork, and perseverance drive innovation and operational excellence.

Key Takeaways

Standardized processes reduce bottlenecks and improve efficiency, accuracy, and scalability.

1. Standardizing processes can dramatically improve efficiency, accuracy, and scalability—turning critical bottlenecks into streamlined workflows.
2. Collaboration, mentorship, and a supportive culture empower engineers to innovate, lead change, and deliver solutions that strengthen mission-critical capabilities.

In the end, these conversations would pay off. With over one hundred hours of work logged for the project, and the support of those around her, Mindy created a new standardized scalable test architecture design and implementation. This is a novel test methodology that validates the design of the chips to allow for proper functionality.

Now, nearly 60 programs at ATL are using her solution for validation. Through a combination of hardware and software improvements, the new validation process ensures a seamless transition of products from wafer to interposer, creating something that is highly scalable and reusable.

“Microelectronics validation is a critical part of chip assembly. With this standardization, we shorten the process while making it more efficient, effective and accurate,” Mindy said. And for critical items like chips, time is not only money, but the core of a system’s ability to come to life.
