Background
Advanced optical components like AR/VR waveguides generate vast amounts of measurement data during quality control. When multiple vendors are supplying different configurations, tracking performance and yield across builds becomes a massive data management challenge.
The Challenge
Engineering teams are often overwhelmed by high-dimensional optical KPI data. Different vendors provide data in varying formats, and the relationships between different optical performance metrics are not easily comparable. Making objective, rapid disposition decisions at OQC is difficult without a unified framework, often requiring hours of manual data wrangling.
The Approach
We developed a systematic framework to build structured data pipelines specifically for optical test data:
- Data Standardization: We designed parser scripts to ingest varying vendor data formats into a unified schema.
- Specification Mapping: We mapped the ingested data directly against product specification tables, automatically flagging out-of-tolerance parameters.
- KPI Family Grouping: We organized hundreds of individual metrics into logical “families” (e.g., efficiency, uniformity, stray light) to make the data digestible.
- Dashboard Implementation: We built interactive dashboard views that presented automated Cpk (process capability) calculations, yield trends, and cross-vendor comparisons.
The Outcome
This automated dashboard workflow transforms the OQC process. What previously took days of manual analysis is reduced to minutes. The quality team gains immediate visibility into supplier performance trends, enabling clearer, faster release decisions and accelerating the overall hardware development cycle.
