Smart Cupping and Scraping Massager PCBA
A representative compact negative-pressure platform for controlled suction, dynamic release, optional warming, battery charging, local indication, and wireless session control.
Project context
How this product is typically engineered
A representative compact negative-pressure platform for controlled suction, dynamic release, optional warming, battery charging, local indication, and wireless session control.
System architecture
Typical architecture
A rechargeable battery powers an MCU, pump switch, pressure input, and controlled or normally open release path; optional heater and NTC channels share a supervised session state machine.
Engineering risks to resolve
Decisions to close before release
- Guarantee rapid return to atmospheric pressure after any single control failure.
- Maintain repeatable negative pressure despite seal leakage, sensor drift, and battery variation.
- Keep condensation and pump noise away from the pressure sensor, electronics, and antenna.
Validation plan
Checks to define before production
- Calibrate against a standard chamber and record evacuation time, setpoint error, leakage, peak pressure, and release time.
- Inject blocked tubing, pump-switch failure, suspected sensor drift, valve failure, reset, and battery faults.
- Run pneumatic cycles, seal aging, moisture-return, charge, wireless, and optional heat-uniformity endurance.
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: Calibrate against a standard chamber and record evacuation time, setpoint error, leakage, peak pressure, and release time.
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
- Closed-loop negative-pressure control.
- Controlled and manual release planning.
- Battery, UI, and optional heating integration.
Technical image review
Board-level evidence
White-background views are published to make component placement, interfaces and assembly boundaries easier to inspect.
