MacroFab for Assembled PCB Prototypes: Fit and DFM Guide

This is a fabricator fit manufacturing profile for MacroFab assembled prototype. The board profile below is a process-specific baseline that still needs order-specific confirmation, not a guaranteed price or capability.

Capabilities, prices, lead times, approved materials, assembly stock, shipping, and taxes change. Requote the exact revision and retain the supplier's order-specific confirmation before release.

• MacroFab can fit teams wanting North American turnkey assembly, sourcing visibility, revision history, and a path from single prototypes toward production.
• Prepare vendor-neutral source and outputs first: versioned KiCad data, Gerbers, drills, fabrication drawing, exact BOM, placement data, stackup intent, and explicit approved substitutions.

Upload a controlled release with stackup intent, inspect parsed layers and board data, resolve DFM feedback, and freeze the quoted factory/process combination.

• Use the vendor's current quote result and order-specific engineering confirmation as authority; published capability tables are screening aids, not approval for every material and option combination.

• Review exact BOM matches and alternatives, consigned inventory, attrition, package/inspection requirements, placement data, and any functional-test RFQ.
• Confirm whether parts are customer-supplied or sourced, how alternates are approved, which placement side and package limits apply, and what happens to unused inventory.

Validation plan:

• Track the exact revision through manufacturing, retain quality/order records, inspect delivered units, and run product-specific bring-up and acceptance tests.
• Inspect the portal render, drill and layer mapping, assembly placement preview, first-article photos or reports, and delivered boards; retain the uploaded archive and quote options with the release record.

Cost drivers:

• Turnkey components, labor, fabrication, setup, inspection class, coating/box build, test, inventory, logistics, tariff/tax, and volume curve determine cost.
• Compare the complete landed and risk-adjusted job: tooling, setup, components, attrition, stencil, engineering, shipping, tax, rework, communication, and schedule—not a promotional board subtotal.

• Integrated sourcing and audited factories improve control, but no manufacturing platform can infer product requirements or prove function without a defined test.
• A vendor name does not make a board manufacturable or functional; the designer still owns requirements, data correctness, option selection, review, and product validation.

Ask the fabricator directly:

• Which factory, IPC class, stackup, package inspection, sourcing route, and certifications are attached to this exact quote?
• What functional-test files, fixtures, limits, logs, and acceptance criteria must the customer provide?

Vendor note. The official platform supports prototype through production PCBA, digital file intake, sourcing/consignment, revision history, and North American factory routing. Actual factory, process, certifications, parts, inspection, test, price, and schedule are project-specific and must be confirmed in the quote.

1. S1Schematic/PCB parity and unresolved connectivity. Run ERC, DRC with schematic parity, and netlist comparison for the MacroFab assembled prototype release; explain every exclusion rather than suppressing it globally.
2. S2Quoted fabrication-profile compliance. Compare saved copper, holes, mask, outline, and digital file intake, turnkey or consigned sourcing, prototype-to-production assembly, revision tracking, and optional advanced processes constraints with the exact quoted stackup and option set.
3. S1BOM, placement, polarity, and output identity. Require exact MPNs, matched BOM/CPL reference sets, reviewed rotations, one clean outline, and fabrication outputs regenerated from the approved MacroFab assembled prototype source revision.
