03-usb-joystick
Manufacturing readiness
Checked .
Scope: PCB fabrication and assembly files.
Fabrication tier: jlcpcb-tier1.
Current evidence passes the assembly release checks; this does not establish tested hardware performance.
- zone fill: passed — Saved copper area agrees with an independent refill on 4 layer(s).
- Connectivity and design checks: passed — 0 electrical/manufacturing errors; DRC and ERC sub-checks passed; warning counts: diffpair_uncoupled_length=1. Manifest verification is deferred to the artifacts gate.
- Native design rules (DRC): passed — 0 error-level findings on saved copper.
- native refilled drc: passed — 0 error-level findings on saved copper.
- lvs: passed — LVS PASSED over 129 bound pad(s).
- warning review: passed — Per-rule warning table reviewed: diffpair_uncoupled_length=1.
- Manufacturing artifacts: passed — Retained package manifest, source provenance and archive bytes verified.
- Bill of materials: passed — 17 BOM line(s) carry procurement identifiers; part check WARN: 10 of 38 assigned item(s) verified (offline catalog and parts cache); 28 unverifiable (not in parts cache or offline catalog) [unverified: U1 -> C44854, U2 -> C7519, F1 -> C126817, Y1 -> C2442665, J2 -> C265104, J3 -> C21285200, R1 -> C105580, R2 -> C105580 (and 20 more)]; CPL includes 1 through-hole component(s) for fab assembly.
Passed: this check passed for the recorded files. Failed: this check found a problem. Not run: no result was established. Unlisted checks have no reported result.
