Layerohm: PCB Stackup

About Layerohm: PCB Stackup

Layerohm: PCB Stackup is a focused, fully on-device app. PCB stackup and transmission-line lab for microstrip, stripline, grounded coplanar waveguide, differential pairs, propagation delay, conductor/dielectric loss, and thermal vias.

KEY FEATURES
- Microstrip impedance sweep
- Differential, delay and loss cues
- Editable stack records
- Local coupon-photo evidence
- Editable sample data and CSV import
- Side-by-side scenario comparison
- Local PDF evidence export
- Fifty-three original offline reference plates

ONE-TIME AND PRIVATE
- One paid download; no subscription or in-app purchase
- No account, advertising, analytics, tracking, or developer-operated backend
- Core features and bundled content work offline
- Work remains on device unless you deliberately share or export it through an Apple system interface

Impedance estimates are pre-layout aids. Confirm the final stackup, material properties, copper geometry, fabrication tolerances, field-solver results, and manufacturer guidance.
