Project context
How this product is typically engineered
A representative Connected scalp massager PCBA reference: motorized massage, optional zoned light output, wireless control, thermal supervision, interlocks, and charging.
System architecture
Typical architecture
An MCU and antenna region coordinate motor drivers and, where the product SKU includes light sources, calibrated constant-current zones; temperature, current, and contact or shielding inputs gate the session.
Engineering risks to resolve
Decisions to close before release
- Protect a large open-ring board and its interconnects from bending and drop stress.
- Control motor noise, hair-entanglement risk, and real-wear wireless attenuation.
- If light output is fitted, maintain zone uniformity, dose limits, and contact interlocks.
Validation plan
Checks to define before production
- Run mechanical stall, hair-interaction, vibration, cleaning, sweat, and enclosure-flex tests.
- Measure radio performance with the device worn and the motor active.
- For light-enabled SKUs, calibrate each zone and verify optical output, temperature, timing, and interlock faults.
What to put in the RFQ
Files and records to agree before quoting
Use this list to agree the build inputs and release records for a similar product. The final set depends on the project.
Design baseline
Released schematic or block diagram, interface table, power states, critical constraints, and revision owner.
Manufacturing release
Gerber or ODB++, stack-up, centroid data, assembly drawings, approved DFM dispositions, and panel assumptions.
Material control
Released BOM revision, manufacturer part numbers, AVL or alternate rules, no-substitute lines, MSL handling, and exception approvals.
Validation record
Test method, acceptance criteria, sample or serial identity, measured result fields, and disposition. Example scope: Run mechanical stall, hair-interaction, vibration, cleaning, sweat, and enclosure-flex tests.
Production release
First-article status plus the agreed SPI, AOI, X-ray, ICT, FCT, programming, rework, OQA, labeling, and packing records.
During RFQ review, we confirm the required fields, sampling, limits, approvals, and record-retention period. Confidential project information stays within the agreed access rules.
Development and production controls
Typical manufacturing scope
- Wearable motor-control integration.
- Optional zoned constant-current outputs.
- Wireless session and safety-state management.
Technical image review
Board-level evidence
White-background views are published to make component placement, interfaces and assembly boundaries easier to inspect.
