Panel Yield Without Assembly Surprises
A panel with a high geometric utilization is not automatically an economical production panel. Rail handling, depanelization, test access and component overhang can change the practical board count. Define those requirements before optimizing a rectangle.
Compare the whole manufacturing flow
Start with the supplier panel size and reserve rails on every edge. Enter board dimensions and routing gaps, then compare both uniform orientations. Ask whether V-scoring or routing imposes direction or spacing limits. Reserve fiducials and tooling and check component clearance to breakaway features. Review assembly conveyor support and the force applied during depanelization. A slightly lower utilization may be preferable when it reduces damaged boards, simplifies test or improves handling. Document the final panel drawing with both fabricator and assembler approval.
