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
A representative engineering program
A representative compact negative-pressure platform for controlled suction, dynamic release, optional warming, battery charging, local indication, and wireless session control.
System architecture
How the electronics are organized
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 close
What must be resolved 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
Evidence expected 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.
Decision-ready evidence packet
What a comparable RFQ should define
This checklist turns the technical story into reviewable inputs and release records. It describes what buyers and manufacturers should agree—not a claim that every listed record applies to every build.
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.
Project-specific fields, retention periods, sampling rules, measured limits, and customer approvals are confirmed during RFQ and protected under the applicable confidentiality agreement.
Development and production controls
Manufacturing scope represented here
- Closed-loop negative-pressure control.
- Controlled and manual release planning.
- Battery, UI, and optional heating integration.
