Full-Coverage Head Compression Massager PCBA

Project context

A representative engineering program

A representative multi-channel pneumatic control architecture for zoned head compression with optional warming or vibration, local interface support, wireless coordination, and default pressure release.

System architecture

How the electronics are organized

An MCU and wireless module schedule a pump and multiple valve channels through protected low-side drivers; pressure, temperature, current, and optional position signals supervise each inflation, hold, and release phase.

Engineering risks to close

What must be resolved before release

• Map many valve, pump, and sensor channels without assembly errors.
• Maintain comfortable pressure across different head shapes while limiting noise.
• Return every chamber to a releasable state after reset, disconnect, or low battery.

Validation plan

Evidence expected before production

• Test each pneumatic channel for flow, pressure rise, hold leakage, blocked tubing, and full-release time.
• Inject valve, pressure-sensor, pump-current, communication, and power-loss faults during every state.
• Run multi-zone endurance while tracking valve response, pump noise, temperature, and tube retention.

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.

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
