Kicad Manufacture

KiCAD Manufacturing & Fabrication Workflow

Prepare manufacturing outputs through Konnect MCP tools. Treat each tool result as evidence with a named scope: a successful request is not by itself proof of a complete, current, upload-ready package. A required check or artifact that cannot be established makes the manufacturing verdict INCOMPLETE.

Toolset loading

Load the required toolsets:

load_toolset('pcb_export')       # Gerber, drill, BOM, position, 3D, and direct DRC evidence
load_toolset('manufacturing')    # Package export, manufacturing preflight, and rough cost estimate

Load additional toolsets only for the branch that needs them:

load_toolset('sch_analysis')     # schematic inventory and footprint assignment
load_toolset('integration')      # local JLCPCB catalogue and alternatives

Call get_active_toolsets() before loading more.

References by manufacturing branch

• Read references/gerber-layers.md when selecting plot layers or accepting a generated artifact inventory.
• Read references/jlcpcb-rules.md only when JLCPCB is the selected fabricator or assembler. It defines how to capture the current order contract without caching volatile limits, prices, categories, or field names in this skill.

1. Capture the order contract

Before checking or exporting, record the selected fabricator, service tier, stackup, copper weight, finish, assembly sides, stencil requirement, quantity, and any controlled-impedance service. Record the source and retrieval date for every vendor-controlled requirement. Project rules and output acceptance are judged against that record.

Completion criterion: every applicable fabrication and assembly constraint has one current authority, and no decision rests on an undated table in this skill.

2. Establish direct design evidence

Run direct KiCad DRC against the saved target board and resolve every error or record a deliberate, reviewable waiver. Then run:

validate_for_manufacturing(board, fab_house?)

The current handler checks only:

• presence of at least one Edge.Cuts item;
• presence of footprints;
• the configured minimum trace width against its built-in fab profile;
• the coarse case where several nets exist but no routed tracks exist; and
• direct kicad-cli DRC evidence, which must be available and complete for a READY verdict.

Read verdict, issues, and drc together. A null or incomplete drc, a NOT READY verdict, or an unadjudicated issue blocks release.

This preflight does not prove outline closure, copper on every pad, drill-size acceptance, silkscreen clearance, stackup compatibility, or assembly readiness. Establish those separately with direct DRC, the selected fabricator's current contract, Gerber/drill inspection, BOM/CPL review, and the order preview.

Completion criterion: direct DRC is complete, every reported issue is resolved or waived, and every check outside the handler's stated scope has named evidence.

3. Export into a fresh destination

Prefer a new, empty output directory for each invocation. This makes stale files structurally unable to impersonate output from the current invocation.

For a package attempt:

export_manufacturing_package(board, output_dir, fab_house?, schematic?)

Pass schematic when assembly output requires a BOM. The tool attempts Gerber, drill, position, and BOM exports according to the request; individual failures can still leave a partial directory.

Artifact acceptance gate

1. Inspect warnings and files_generated. Any warning or missing requested artifact type keeps the result INCOMPLETE.
2. Reconcile the requested copper, mask, silkscreen, paste, and Edge.Cuts layers against the actual files in the fresh output directory.
3. Confirm every required artifact is a regular, non-empty file produced by the current invocation. A directory entry, reported path, or zero exit status is not enough.
4. Confirm the required plated and non-plated drill outputs for the actual board hole inventory. Absence is acceptable only when the design proves that output is inapplicable.
5. Open the Gerbers and drills in a viewer. Inspect layer registration, outline, apertures, holes/slots, mask, paste, and silkscreen.
6. For assembly, inspect BOM contents, DNP handling, designator coverage, CPL side/units/origin/rotation, and the fabricator's export preview.

The current files field is a directory listing and can include pre-existing entries; files_generated records successful export calls but does not prove that every reported output is fresh and non-empty. If a later tool response provides an explicit verified artifact manifest, accept that stronger evidence only for the artifacts and postconditions it names. Preserve the viewer and order-preview checks.

Completion criterion: an accepted manifest accounts for every required output, every accepted path is fresh and non-empty, and visual/order previews agree with the saved design.

4. Use manual exports when control is required

Use the individual tools when a package needs explicit layer, BOM, side, unit, or filename choices:

export_gerber(board, output_dir, layers?, drill_file?)
export_bom(schematic, output, format?, fields?, group_by?, labels?, exclude_dnp?)
export_position_file(board, output, format?, side?, units?)

Apply the same fresh-destination and artifact acceptance gate. A manual sequence does not lower the evidence requirement.

5. Treat cost output as a heuristic

estimate_cost(board, quantity?, layers?, fab_house?)

estimate_cost is an indicative heuristic built from fixed assumptions and rough average component costs. Use it only for coarse comparisons. It is not a vendor quote and does not know the selected finish, service, complete BOM, shipping, taxes, coupons, or current pricing. Budget and purchasing decisions require a current quote from the selected fabricator.

6. Record manufacturing acceptance

The final report must include:

• saved design revision or hash;
• direct DRC status and any explicit waivers;
• validate_for_manufacturing verdict, issues, and DRC coverage;
• selected fabricator/order contract with source and retrieval date;
• accepted artifact manifest with file type, path, and non-empty evidence;
• Gerber/drill viewer result;
• BOM/CPL and order-preview result when assembly is in scope;
• 3D/enclosure inspection status when mechanically relevant; and
• final READY, NOT READY, or INCOMPLETE verdict.

Only READY permits upload. Preserve the accepted manifest rather than telling the user to upload every entry found in a reused directory.
