TOPIC FOCUS
Turn review findings into controlled decisions
Record each issue against the affected revision, identify the owner and disposition, update source files consistently, and retain the evidence used for release.
PCB Design & DFMA
DFMA and Production Readiness
Production readiness depends on a frozen design package, documented return paths, thermal and mechanical constraints, fabrication and assembly rules, verification coverage, and controlled change approval.
APPLICATION BOUNDARY
Confirm against the released project
A DFMA checklist cannot replace project review. Product use, stackup, components, enclosure, assembly route, programming, test access, compliance, and reliability requirements determine the applicable checks.

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 |
|---|---|---|
| Design release | Source files, firmware, BOM and drawings | One revision-controlled handoff |
| Open issues | Fabrication, assembly, thermal and test findings | Owner, decision and closure evidence |
| Pilot decision | Verification coverage and approved changes | Release record for next build |
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.
HDI PCB Design
WiFi Bluetooth core board design
WiFi/Bluetooth core board design: for the 35mm by 30mm target, UART/SPI access, and actual enclosure, define two work packages. Module versions check antenna clearance and bridging; IC versions add crystals, matching, and RF debugging. Align prototypes, network configuration, and in-enclosure communication tests before comparing development effort and subsequent materials, rather than module/IC prices alone.

Multilayer PCB Design
Eight-channel synchronous acquisition board design
Eight-channel simultaneous acquisition board design: request separate quotations for eight front ends/error budgets, common clocks, SPI buffering/upload, and per-channel calibration. 8kSPS per channel is a reference target; align input ranges, storage formats, and upload endpoints when comparing quotations. PCB-only work cannot be compared directly with development including host calibration software.

Multilayer PCB Design
Industrial Ethernet control board design
Industrial Ethernet control board design: list endpoints and tasks for reference 1-port 10/100M, 2-port RS485, optional CAN, and 8 inputs/4 outputs. Hardware includes input protection, PHY, and field I/O; software includes protocols, logs, and rollback. Quote network-saturated/concurrent-load prototypes separately rather than estimating all industrial development from one Ethernet port.

High-Frequency PCB Design
5.8 GHz microwave PCB design
5.8 GHz microwave PCB design: first commission 5.8GHz passive through paths, port transitions, and same-board reference structures, then insert filters for comparisons at identical reference planes. Active-gain extensions require separately selected in-band devices, biasing, and stability tests. Quote all three work packages separately; obtain comparable loss data before expansion so passive pricing is not mistaken for active-system pricing.

Rigid-Flex PCB Design
Wearable rigid-flex PCB design
Wearable rigid-flex design: bundle basic motion acquisition, Bluetooth, and single-cell lithium power; separately list optional GNSS, charging structures, and system battery-life tests. Rigid 4-layer/flexible 2-layer construction awaits joint review. Confirm static forming/worn-position verification first; do not ambiguously bundle dynamic lifetime, positioning, and system tests into one rigid-flex fee.

PCB Design Knowledge
How does PCB design connect fabrication and SMT assembly? Manufacturing coordination checklist
This checklist adds cross-process issue tracking, approval authority, manufacturing-release gates, and change-regression scope. Via-in-pad, material-substitution, and test-access examples explain how fabrication feedback updates design/first articles, preventing revision conflicts after local issue closure.
