Design for manufacturing means aligning the design and deliverables with the actual fabrication and assembly process. Trace prepares design-side files and checks; the manufacturer reviews them and prepares its own production programs.
The Line
Bare-board fabrication and component assembly are separate stages. Assembly may include stencil printing, solder-paste inspection (SPI), placement, reflow, and optical inspection (AOI), with additional manual or automated work depending on the product.
An export does not directly configure every machine, eliminate human review, or supply physical test evidence.
What Trace Outputs, and Which Machine Consumes It
- Copper, mask, silkscreen, and outline Gerbers: fabrication/reference geometry reviewed by the fab's tooling process.
- Drill files: hole locations, sizes, and applicable plated/non-plated information. Special drilling processes need explicit agreement.
- Paste-layer geometry: input for stencil design. The assembler may adjust apertures; it is not a complete stencil-printer or SPI program.
- BOM: fitted references, quantities, and exact orderable parts for sourcing and assembly preparation.
- Position files: locations, rotation, and side used to prepare placement programs after origin/rotation mapping.
- Assembly drawings and 3D/mechanical files: supporting orientation, fit, and assembly review.
Confirm the selected variant, units, origin, and naming with the receiving manufacturer. SPI/AOI programs, feeder setup, panelization, and reflow profiles are not universally generated from these files by Trace.
DFM Enforcement: Catching Problems Before the Line
Use the saved design, actual manufacturer requirements, and reviewed outputs together. Automated findings cover only their configured checks.
Manufacturer DRC Presets
Select or import the intended rule set, check its process/layer/copper assumptions, and run DRC. Presets encode selected constraints; they do not guarantee fabrication yield, stencil quality, solder joints, or assembled function.
Retain custom rules before replacing them. Default (no manufacturer) means baseline board/net-class rules, not no constraints. See DRC Import.
AI-Assisted Order Autofill
Native autofill measures board facts first and assists with order choices. Check dimensions, stackup, copper, quantity, finish, assembly, and shipping before submission. Autofill is not manufacturer approval or an instant quote.
Why This Matters for Automation
Consistent deliverables reduce avoidable preparation errors. Before sending:
- Confirm the saved revision and fitted variant.
- Run relevant ERC/DRC checks and review unresolved requirements.
- In the native ordering dialog, use Generate Production Files, then inspect the actual Gerber/drill ZIP, BOM, and position files reported by that generation before Send. The GUI variant is not passed to this dialog's BOM/position generation; separately exported variant files are not automatically used for submission. Do not send an assembly package that differs from the intended fitted parts.
- Confirm special processes, stackup, assembly sourcing, and coordinate conventions.
- Review the manufacturer's questions and quote before approving production.
A clean DRC report does not establish manufacturer acceptance, and AOI/SPI findings do not by themselves establish electrical function.
Manufacturer-Owned Production Steps
The assembly partner determines stencil changes, feeders, placement calibration, inspection programs, and a suitable reflow process. Reflow peak temperature is not the solder alloy's liquidus temperature; the process must respect paste, board, and component specifications.
Trace design outputs do not authorize or control physical machinery, and they do not provide per-board physical measurements or a universal production PASS. No future automation commitment is implied here.
Integration Surface
Use the formats supported by the installed exporter and requested by the manufacturer, including Gerber/drill and reviewed BOM/position data, or IPC-2581/ODB++ where applicable.
Standard file extensions do not guarantee interchangeable units, origin, rotation, variant handling, or direct machine compatibility. Keep the submitted artifacts and resolve incomplete or uncertain submissions through the original order rather than duplicating it.
