Why realistic package data matters for 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 not consistent across different designs and customers. As a result, clearance, manufacturing, and physical analyses can trigger prematurely or become difficult to compare.
The Package Expert addresses this gap. This optional web-based add-on for PCB-Investigator helps assign realistic component bodies to parts in your design, creating a consistent digital twin of the assembly even when the original component data is incomplete.
How Package Expert supports your workflow
The service matches existing component information such as geometry, pin count, package type, description, or manufacturer details against an online library of real packages. Based on that data, you receive well-founded suggestions for suitable 2D outlines and, where available, matching 3D models.
This removes much of the manual effort involved in searching libraries or defining packages individually. For large designs and mixed data sources, that means a cleaner and more consistent analysis foundation.
Benefits for engineering teams
- More reliable clearance and manufacturing checks: Rules are applied to actual component bodies instead of rough placeholders.
- Better thermal and physical simulation results: Oversized packages no longer distort volume, mass, or interpretation.
- Consistent analysis across projects: Results become easier to compare between customers, designs, and revisions.
- Less manual library work: Teams save time, especially in early development or with legacy data.
Realistic component geometry is not a detail; it is the basis for trustworthy PCB analysis.
Package Expert is especially useful for EMS providers with existing MPN data, but also for teams working with internal part numbers or incomplete component information. Even without complete manufacturer details, suitable package candidates can be identified using geometry and pin structure.
