TOPIC FOCUS
Give the prototype a specific learning objective
Separate fit, electrical function, process learning, firmware, test development, regulatory work, and pilot preparation so the build quantity and evidence match the decision.
PCB Fabrication
Prototype Planning
Prototype planning starts by defining what the build must prove, then aligning fabrication files, BOM and placement data, quantity, acceptance criteria, test evidence, and the decision required before the next build.
APPLICATION BOUNDARY
Confirm against the released project
A successful prototype does not automatically prove volume readiness. Material availability, fixtures, programming, inspection, yield controls, traceability, process windows, and change control need separate release evidence.
PROJECT FLOW

Decisions to document before release
Use this topic-specific checklist with the linked engineering reference. Record the actual project conditions and the agreed acceptance scope.
| Decision | Input to confirm | Record to retain |
|---|---|---|
| Learning goal | Fit, electrical, process or firmware question | Decision the prototype must answer |
| Build inputs | Files, BOM, quantity and test conditions | Versioned build and acceptance package |
| Next build | Failures, changes and unresolved risks | Retest and pilot-readiness record |
Use published configurations to frame the next engineering question
These records provide context for the topic. They do not replace review of the current files, materials, quantities, tests, or acceptance conditions.
PCB Prototyping
Four-Layer PCB Prototype
Four-layer functional prototypes: review verification objectives, Gerber revisions, sample variants, and production change records. All values are illustrative; approve fabrication drawings and acceptance criteria before ordering. Assembly and system verification require separate scope.

PCB Prototyping
Six-layer impedance PCB prototyping
Six-layer impedance prototypes: review target nets, representative coupons, measured stackups, and raw TDR records. All values are illustrative; approve fabrication drawings and acceptance criteria before ordering. Assembly and system verification require separate scope.

Prototype PCB Assembly
Motor driver PCBA prototyping
Motor driver prototype assembly references cover three-phase drives and current/position-feedback checks. Compare materials, SMT, later-installed power parts, staged power-up and energy-limited testing. Define gate, phase-sequence, sampling, controlled-load and protection tests, and retain measurement records and component-change revisions.

Prototype PCB Assembly
Communication interface PCBA prototyping
Communication interface prototype PCB assembly reference configurations cover serial/bus/network interface verification. Separate SMT, interface post-soldering, test software, and protocol integration testing; compare material supply, setup, and per-lot assembly costs. Check loops, packets, error injection, and power-loss/disconnection recovery scope, plus samples + packets/waveforms + issue/revision-list deliverables.

HDI PCB
Six-layer single-build-up HDI PCB prototyping
Review thin six-layer 1-4-1 HDI PCB prototyping for compact sensor modules. Define via-layer pairs, filling and pad-flatness requirements, finished copper, panel support, thickness, and warpage acceptance.

Engineering Applications
Which files are needed for PCB prototyping? Gerber, drill, and board-outline checklist
Prepare a consistent PCB fabrication package with Gerber data, drill files, board outlines, a revision manifest, stackups, and via layer pairs. Resolve conflicts between drawings, drill dimensions, and fabrication notes before release.
