Why geometry quality defines the value of PCB analysis
Many PCB analyses depend entirely on the quality of the underlying geometric data. In practice, CAD packages are often oversized, inconsistently modeled, or inconsistent across designs and customers. The result: clearance, manufacturing, or physical analyses may trigger too early, or their outputs become difficult to compare.
Package Expert from PCB-Investigator closes that gap. This optional, web-based add-on helps assign realistic component bodies to parts in the design, creating a more consistent digital twin of the assembly, even when the original component data is incomplete.
How Package Expert works
The service looks for suitable 2D package outlines and, where available, 3D models for components in the current PCB design. It uses existing information such as geometry, pin count, package type, description, or manufacturer details and matches that data against an online library of real packages.
Instead of manually researching or defining every package, users receive well-founded suggestions based on technical attributes. That reduces effort and improves data consistency across projects.
Why realistic component bodies matter
Many PCB-Investigator analyses are component-specific. If the packages used in the design do not reflect the real component body, clearance rules, manufacturing rules, and keep-out definitions lose significance.
Realistic component bodies are the foundation for robust, comparable, and trustworthy analysis results.
Physical simulations benefit as well. Oversized packages distort volume and mass, which can affect calculations such as thermal analysis. Realistic geometries keep results closer to actual operating conditions and improve their interpretability.
Who benefits most from Package Expert?
- EMS providers with MPN data: Real manufacturer part numbers can be used to assign highly accurate package data and corresponding 3D models.
- Teams with incomplete data: Even without known MPNs, suitable component bodies can be identified from geometry, pin structure, and descriptions.
- Teams working with legacy designs: Historical libraries and inconsistent package names can be normalized for better comparability.
The result is a more reliable data basis for early development phases, variant management, and demanding analysis workflows.
