AutoPhi BGA Library — AUTOPHI_BGA1536 (v1)

The 1,536-ball entry of the AutoPhi BGA library. 95 mm × 90 mm package, 2.0 mm pitch. Validator-clean v1 release.

AUTOPHI_BGA1536 (v1) is the large-package entry of the canonical AutoPhi BGA library at the 1,536-ball size class — 95 mm × 90 mm package, 2.0 mm pitch. The release is a coherent set of three artifacts (footprint, pinmap template, working symbol) that all reference the same canonical pin grid, generated from the library's standard scripts and validated via the library's standard pass/fail validator. Sits at the upper edge of the AutoPhi board family's mechanical-clearance envelope (95 mm) by design — the test case for the largest package the series carries.

Mechanical Envelope

The AutoPhi board series mechanical-planning envelope for BGA interchange is up to 95 mm, based on the latest board mechanical-clearance updates. AUTOPHI_BGA1536 sits at the envelope's edge (95 mm × 90 mm) by design and is the test case for the largest package the series can carry. The 256-ball companion (20 mm × 20 mm) sits well inside that envelope.

How AUTOPHI_BGA1536 (v1) Was Built

The v1 release is the deterministic output of the library's standard pipeline applied to the larger size class:

1. scripts/generate_bga_footprint_grid.py with — profile v19_default — rows 32 — cols 48 — pitch 2.0 generates the parametric 1,536-ball footprint.
2. scripts/generate_bga_pinmap_template.py derives the pinmap CSV directly from the footprint's pads.
3. scripts/initialize_pinmap_working.py initialises the working pinmap from the template.
4. scripts/seed_ab_domains.py seeds provisional canonical domains across all rows for large BGAs.
5. scripts/promote_provisional_signals.py promotes provisional names to stable canonical names.
6. scripts/finalize_power_rails.py finalises voltage-domain placeholders.
7. scripts/normalize_pinmap_notes.py normalises duplicate note tags.
8. scripts/generate_bga_symbol_from_pinmap.py generates the KiCad symbol from the working pinmap.
9. scripts/validate_bga_library.py confirms pinmap + symbol + footprint alignment.

Re-runnable end-to-end via scripts/rebuild_provisional_seed.ps1 with row arguments covering the full 32-row range.

USPTO Patent Status

The BGA library underpins board projects covered by the AutoPhi patent portfolio — principally USPTO 18/370,908 (AutoPhi quantum-battery and propulsion IC) and the umbrella USPTO 19/540,453 (Integrated Technology Portfolio) — through the board projects that consume it. The library itself is engineering source-of-truth content rather than a separately-claimed invention; its patent value is its role as the canonical foundation for the board-project filings that depend on it.

How it's made

AUTOPHI_BGA1536 (v1) is built by running the same generation pipeline that produces the 256-ball release, with the larger row/column dimensions and pitch as input parameters. The footprint is parametrically generated; the pinmap is derived from the footprint pads ball-for-ball; the symbol is generated from the pinmap. The resulting three artifacts cannot drift from each other because they are produced by the same scripted chain.

The library's governance documents (POWER_POLICY.md, CANONICAL_DIMENSIONS_MATRIX.md, LIBRARY_GOVERNANCE.md) apply equally to both size classes — the 256-ball and 1,536-ball releases share the same canonical signal naming, the same voltage-domain seeding policy, and the same release-acceptance gate. The buyer who acquires both (or either) takes the same governance discipline.

Why I made it

The AutoPhi board series consumes BGAs at multiple size classes. The 256-ball BGA covers the small-package board projects; the 1,536-ball BGA covers the large-package board projects (high-bandwidth memory interfaces, multi-die interposers, top-of-the-line compute substrates). Maintaining both as ad-hoc per-board artifacts would invite drift between the canonical pin grid and any given board's pin assignments. Maintaining both inside one library, with the same generation pipeline and the same validator, makes drift impossible.

The 1,536-ball v1 release is the upper-edge mechanical test for the AutoPhi board series. It also serves as the foundation that future (larger or higher-pitch) entries in the library will be parametrically generated against.

What it can do

An acquirer who licenses AUTOPHI_BGA1536 (v1) takes possession of the 95 mm × 90 mm KiCad mechanical footprint, the working pinmap CSV with seeded canonical signal/voltage assignments, the generated KiCad symbol library, the full set of generation / seeding / normalisation / promotion / finalisation / symbol-generation / validation / reporting scripts (shared with the 256-ball release), and the library governance documents.

What the library is not: it is not a finished board layout. The library guarantees that the BGA component a board project references is internally consistent and validator-clean; the board's own routing, placement, mechanical decisions, and signal integrity remain the buyer's downstream responsibility.

Why it's a fact

• The footprint BGA-1536_95x90mm_P2.0mm.kicad_mod, the working pinmap CSV, and the working KiCad symbol are inspectable on disk under D:\special\40-autophi-bga256\. They can be opened in KiCad.
• The pipeline scripts are reproducible Python and PowerShell. Buyers can re-run the rebuild and confirm v1 outputs match the released artifacts.
• The 95 mm mechanical envelope claim is stated in the library's own README and grounded in the canonical-dimensions-matrix governance doc.
• The companion 256-ball release is independently inspectable in the same library folder; same governance, same scripts, different size class.
• Per PATENT_LINKAGE_REPORT.md, the library underpins board projects covered by USPTO 18/370,908 and 19/540,453 umbrella.

License Terms — What's Granted, What Isn't

The acquisition grants the buyer permission to make, build, and copy the deliverable. It does not transfer the underlying intellectual property:

• Granted with the acquisition: permission to use the canonical 1,536-ball BGA footprint, pinmap, and KiCad symbol in the buyer's own board projects; permission to build boards consuming the library; permission to make copies of the library for the buyer's engineering and team-distribution use; permission to run the generation, validation, and reporting scripts against the buyer's own pinmaps.
• Not transferred with the acquisition: the AutoPhi quantum-battery / EM propulsion IC patents (USPTO 18/370,908 and 19/540,453) that the consuming board projects fall under, the inventor's broader BGA library work, trademarks, copyrights, or any rights to license or assign the IP onward. The intellectual property remains held by Christopher Gabriel Brown.
• The buyer's permission is to use the library, not to own the rights behind the library.

This framing applies uniformly across the inventor's portfolio. Buyers seeking IP assignment rather than make/build/copy permission should contact the inventor directly — that is a separate negotiation outside the standard storefront acquisition.

Same library, same governance, larger package class. The 95 mm test case for the AutoPhi board series.

A buyer who acquires AUTOPHI_BGA1536 (v1) takes the canonical 1,536-ball BGA component for the AutoPhi board family. Same generation pipeline as the 256-ball release; same validator; same governance docs. Permission to make, build, and copy.
