Production Line:
Power Adapter Manufacturing Process
1. Design & Prototyping
- Circuit design: Engineers create schematics and PCB layouts using CAD tools, ensuring compliance with safety standards (e.g., UL/IEC).
- Prototype testing: Functional verification, thermal analysis, and EMI/EMC testing are conducted.
2. Component Sourcing
- Procurement of key components:
• Transformer cores and copper windings
• Power ICs and MOSFETs
• Capacitors (electrolytic/X7R)
• Connectors (USB-C, barrel jacks, etc.)
- Incoming quality control (IQC) checks for component specifications.
4. Transformer Production
- Bobbin winding with enameled copper wire
- Core assembly (EE/EI/ferrite types)
- Varnish dipping for insulation and vibration resistance
- Inductance and turns ratio testing
5. Assembly & Integration
- Housing assembly: Injection-molded plastic cases with UL94-V0 flame rating
- Potting (for industrial units): Filling with thermally conductive epoxy
- Final assembly: Integrating PCB, transformer, and cooling components (heat sinks/thermal pads)
- Strain relief installation for cables
6. Testing & Quality Assurance
- Electrical Tests:
• Load regulation (±5% typical)
• Ripple/noise measurement (<150mVpp)
• Short-circuit/overcurrent protection
- Safety Tests:
• Hi-pot test (3kV AC or equivalent)
• Insulation resistance (>10MΩ)
- Burn-in testing (2-4 hours at full load)
7. Packaging & Shipping
- Laser marking for certifications (UL, CE, FCC, RoHS)
- Anti-static packaging with protective foam
- Palletization according to shipping requirements
Key Process Controls: - IPC-A-610 Class II/III standards for PCB assembly
- 100% electrical testing before packaging
- Traceability system for batch tracking
This end-to-end process typically takes 15-30 days depending on order complexity, with automated lines achieving >95% first-pass yield in modern facilities.
