PCB Design Software Programs Compared: KiCad, Altium, OrCAD, and What Fabs Actually Need

Compare KiCad, Altium, OrCAD X, Allegro X, Fusion 360/EAGLE, and DipTrace from a China fab view: pick by complexity, ship clean Gerber and notes.

Tool-tier pyramid and fab release file stack for PCB design software selection

No single PCB design program wins every job. Pick by board complexity, team process, and budget -- then judge the tool by the manufacturing package it can export, not by the logo on the splash screen. From the China fab chair, clean Gerber or ODB++/IPC-2581, NC drill, stackup/fab drawing, pick-place, BOM, and netlist matter more than whether you drew the board in KiCad, Altium Designer, OrCAD X, Allegro X, Fusion 360 Electronics / EAGLE, or DipTrace. This guide compares those suites for overseas EE and procurement, maps decision paths by role, lists what every RFQ must include, and flags the handoff failures that stall CAM -- without treating specialized semiconductor/PI tools (Ansys RedHawk-class rail analysis) as day-to-day layout suites.

What China fabs care about when you name an EDA tool

Fabs care that your release package is complete, revision-locked, and unambiguous -- not which PCB design software logo appears in the project file.

CAM builds from manufacturing outputs. A tidy Altium project that ships a wrong layer map still holds. A KiCad board with a complete Gerber set, drill table, stackup note, and pick-place usually runs. Treat the EDA choice as a workflow and license decision for your team; treat the release package as the contract with the fab.

DRC is not DFM. Passing the tool's design-rule check only proves you met the rules you typed into that tool. Fab DFM adds process windows: etch yield, min annular ring, NPTH vs PTH, mask dams, impedance coupons, via fill, and assembly clearances. Ship both a DRC report and fab-facing notes.

Procurement Pro-Tip: Accept designs from any major EDA suite if the release package is complete. Do not shortlist vendors by "we only take Altium." Shortlist by whether CAM can open a locked rev of Gerber/ODB++, drill, fab drawing, CPL, BOM, and netlist without guessing.

Use this qualitative table to shortlist -- then verify export settings on a real board before you freeze the AVL for layout tools.

KiCadHobby, education, cost-sensitive NPIFull schematic-to-PCB flow; strong community libraries; no seat tax for solo workTeam vault / formal PLM is DIY; library discipline is on youGerber, drill, IPC-2581/ODB++ paths mature when you configure layers carefully; document the layer map

OrCAD XCadence-centric schematic shops, mixed Allegro handoffFamiliar Capture-class schematic; X-platform updatesLayout depth vs Allegro depends on the exact product seatGood manufacturing exports when the release checklist is enforced; align units and layer map early
Allegro XEnterprise high-speed / high-rel / large teamsConstraint-driven layout; scales to dense high-layer workLearning curve and license model (vendor-quoted / enterprise)Strong for controlled fab packages; still needs human fab notes and stackup table

Seat prices are not published here as XFPCB facts -- ask the EDA vendor. Specialized semiconductor power-integrity / rail tools in the Ansys RedHawk class are not substitutes for these layout suites; use them when you have die/package PDN problems, not for everyday FR-4 board drafting.

Decision paths: which PCB design program fits your team

Match the tool to complexity and process maturity, then lock an export checklist before the first China fab RFQ.

1. Hobby / education / one-off prototypes

Choose KiCad or a light Fusion/EAGLE-class flow when boards are 2-4 layers, budgets are tight, and one engineer owns the project. Export Gerber + drill + a one-page fab note (thickness, finish, copper weight). Do not skip NPTH callouts just because the board is "simple."

2. Startup / NPI with a few paid seats

Choose KiCad with strict library rules, DipTrace, or Fusion 360 Electronics / EAGLE when you need speed and light BOM control. Escalate to Altium Designer when you need managed components, multi-board, or frequent ECO with contract layout houses. Freeze a release script early so every spin uses the same Gerber layer map.

3. Professional product team (shipping SKUs)

Choose Altium Designer or OrCAD X (with layout depth that matches your Cadence seat) when revision control, library governance, and assembly outputs are weekly work. Demand ODB++ or IPC-2581 plus classic Gerber as a backup, pick-place, and a fab drawing with stackup. Treat "DRC clean" as necessary but not sufficient.

4. Enterprise high-speed / high-reliability

Choose Allegro X (or Altium with strong constraint and length-match process) when you run dense BGAs, controlled impedance, and formal ECO. Pair layout with the right SI/PI analysis for the interface -- not a semiconductor RedHawk-class rail tool unless you truly have package/die PDN scope. Budget for vendor-quoted licenses and trained owners of the constraint file.

What every tool must export for a China fab RFQ

Every major EDA path must produce the same manufacturing contract -- formats differ, content does not.

Minimum release package:

  1. Copper artwork -- Gerber (RS-274X) or ODB++ / IPC-2581, with a written layer map (Top Copper, Inner1, etc.)
  2. NC drill -- plated vs non-plated holes called out; slots and back-drill noted if used
  3. Fab drawing / stackup -- layer count, copper weights, dielectric/Tg, board thickness, finish, mask/silk, impedance targets with reference layers
  4. Pick-place (CPL) -- centroids, rotations, side, refdes aligned to the BOM rev
  5. BOM -- manufacturer MPN, refdes, DNP lines, and approved alternates where allowed
  6. Netlist -- for assembly/test correlation and ECO checks
  7. Notes -- outline tolerances, via fill, edge plate, gold fingers, UL marks, specials

Common handoff failures that burn RFQ time

Most CAM holds come from package mistakes, not from "wrong" EDA brands.

Four handoff failure icons: layer map, missing NPTH, empty stackup, unit mix
Layer map error, missing NPTH, missing stackup, imperial-metric mix
  • Wrong layer map -- Top copper labeled as silk, or inner layers swapped; CAM etches the wrong intent.
  • Missing NPTH -- mounting holes plated by accident; screws short to copper or press-fit fails.
  • No stackup -- impedance and thickness become shop guesses; quotes are not comparable.
  • Imperial / metric mix -- outline in mm, drill in inches, or library lands mismatched to BOM text.
  • Library footprint errors -- wrong pitch, mirror, or pin-1; first article fails before fab yield is even relevant.
  • DRC-only release -- no fab notes for finish, via fill, or mask dams; CAM invents defaults you did not want.

Watch Out for: Zipping "all outputs" from the EDA without opening the zip. Confirm every Gerber opens, drill tool sizes match the fab drawing, and NPTH holes are marked. A green DRC light does not prove the zip is fab-ready.

PCB design software FAQ

Is there one best PCB design software for every board?

No. Choose by complexity, team process, and budget. Hobby and education often fit KiCad or a light Fusion/EAGLE-class flow; shipping product teams usually need Altium Designer or OrCAD X with library governance; dense high-speed or high-rel work often lands on Allegro X or a tightly constrained Altium flow. From the fab chair, the winning choice is the one that exports a complete, revision-locked manufacturing package.

What files does a China fab need from any EDA tool?

Minimum package: Gerber or ODB++/IPC-2581 with a written layer map, NC drill with PTH vs NPTH, fab drawing and stackup (copper, dielectric/Tg, thickness, finish, mask/silk, impedance if needed), pick-place, BOM, netlist, and fab notes. DRC-clean alone is not DFM. Formats can differ by tool; the content contract does not.

Does XFPCB only accept Altium Designer projects?

No. Procurement should accept designs from any major suite -- KiCad, Fusion 360 Electronics / EAGLE, DipTrace, Altium Designer, OrCAD X, Allegro X -- when the release package is complete. CAM builds from manufacturing outputs, not from the splash-screen logo. Incomplete zips hold regardless of brand.

Are Ansys RedHawk-class tools PCB layout suites?

No. RedHawk-class tools are specialized semiconductor / package power-integrity and rail-analysis products. They are not day-to-day FR-4 schematic-to-layout replacements for KiCad, Altium, OrCAD X, or Allegro X. Use them when die/package PDN scope requires them; keep board drafting in a PCB layout suite and still ship a full fab release package.

What handoff mistakes stall RFQs most often?

Wrong Gerber layer maps, missing NPTH callouts, no stackup table, mixed imperial and metric units, and library footprint errors. Also common: shipping only a DRC report with no finish, via-fill, or mask notes so CAM invents defaults. Open the zip before you RFQ -- green DRC does not prove fab-ready outputs.
