Foundry handoff / free preflight tool
MPW Block Fit Checker
Check die width, height, permitted rotation and per-edge margins against a booked MPW block. Area alone is not a fit test.
What to provide
Die and block dimensions in mm or um, four explicit margins, and permission for 90-degree rotation.
What you get
Both permitted orientations, remaining clearance and a rectangular placement sketch.
Margins stay on the block axes after rotation. Enter the provider-required scribe and keep-out allowances; zero is an explicit assumption. This is one-die placement, not nesting.
No current result. Review inputs, then run the check. Editing an input clears the previous report.

A geometric fit is not foundry acceptance, a shuttle reservation, a die-count estimate or a price.
All built-in examples are synthetic, not product data, customer evidence or supplier commitments. Retain the input revision and review the downloaded report with the responsible provider.
