OEM support for servo drive PCB assembly, SMT production, test fixtures, conformal coating, and electronics manufacturing documentation.
| Program Metric | Typical Range | Procurement Value |
|---|---|---|
| Test coverage | AOI, ICT, FCT, burn-in by project | Servo drive failures are expensive once boards are sealed inside robot joints. |
| Power-stage margin | MOSFET/GaN rating, current sensing, copper, heat path | Compact servo boards fail when electrical, thermal, and enclosure constraints are treated separately. |
| Traceability | BOM revision, firmware version, serial number, fixture log | Traceable electronics records make pilot issues easier to isolate before batch shipment. |
| Situation | Recommended Path | Evidence to Confirm |
|---|---|---|
| The servo drive board must fit inside a compact joint | Reserve test points, heat-spreading copper, connector clearance, isolation spacing, and fixture access before PCB freeze | PCB outline, keep-outs, layer stack, copper weight, test access, connector height, and enclosure section |
| Prototype boards need to become repeatable SMT production | Plan AOI, ICT, FCT, firmware flashing, calibration, burn-in, and serial records as production deliverables | Gerbers, BOM, pick-and-place, firmware image, fixture spec, panelization plan, and inspection limits |
| Power-stage heat or component alternates may change behavior | Control MOSFET/GaN, current sensors, gate drivers, MCUs, connectors, and feedback components under ECO | Approved AVL, alternate list, thermal sample data, load-cycle data, and buyer approval for substitutions |
| Checkpoint | Method | Pass Evidence |
|---|---|---|
| DFM and test access review | Check panelization, component placement, thermal copper, isolation, connector load, and ICT/FCT access | PCB DFM report and accepted fixture access points before layout freeze |
| SMT production validation | Run AOI, ICT/FCT, firmware flashing, calibration, burn-in sampling, and first-article inspection | Serialized PCBA report, approved BOM revision, firmware version, and fixture result |
| BOM alternate control | Approve alternates for current sensors, gate drivers, MCUs, connectors, feedback parts, and power devices | AVL, ECO record, buyer approval, and retest data for behavior-sensitive substitutions |
Program Evidence
For OEM pages, the first engineering review defines execution gates, missing data, and production-readiness evidence before kickoff.
Motor, drive, actuator, firmware, harness, fixture, and test responsibility are separated before quotation.
Open items such as torque-speed data, duty cycle, envelope, protocol, encoder, and target launch country are flagged early.
Prototype checks are tied to load profile, thermal rise, backlash, noise, current limit, and end-of-line pass criteria.
Tooling, fixture, pilot lot, annual forecast, packaging, documentation, and delivery assumptions are made explicit.
| Evidence Group | What to Attach | Buyer Value |
|---|---|---|
| Motion and thermal | Torque-speed target, current limit, duty cycle, temperature path, and derating assumption. | Separates continuous-duty capability from peak torque claims before sample approval. |
| Interface control | STEP or drawing revision, flange, bore, cable exit, connector, encoder, and protocol map. | Keeps motor, drive, harness, and firmware assumptions aligned before tooling. |
| Validation record | EVT, DVT, PVT gate criteria, EOL checklist, burn-in profile, and serial or lot traceability. | Gives engineering and procurement a common pass/fail basis for pilot lots. |
| Commercial path | Prototype quantity, pilot build target, annual forecast, delivery country, and packing notes. | Improves quote precision and avoids late shipping or documentation surprises. |
Yes. Irregular outlines and stacked boards can be reviewed with manufacturing and test constraints included.
Yes. Firmware flashing, calibration routines, ICT/FCT fixtures, burn-in, and serialized reports can be scoped by project.
