The HOULI manufacturing workflow moves from PCB preparation and component assembly through power testing, final assembly, aging verification and final inspection before packaging.


How HOULI Manufactures Pure Sine Wave Inverters
SMT Processing
Surface-mount components are assembled onto PCB boards through controlled solder-paste printing, component placement and reflow processes.
Component Insertion
Through-hole components such as transformers, inductors, capacitors, terminals and power components are inserted according to PCB design requirements.
Wave Soldering
Inserted PCB assemblies pass through the wave-soldering process to create repeatable electrical and mechanical connections for through-hole components.
Post-Soldering & Reinforcement
Critical solder joints, wires, high-current connections and selected components are manually inspected and reinforced where required.
Power Supply & Module Testing
Electrical modules are checked using test instruments before final assembly. Verification can include circuit operation, voltage behavior and power-module performance.
Final Assembly
PCB assemblies, transformers, fans, LCD displays, terminals, cables and other components are installed into the inverter housing.
Aging & Reliability Verification
Completed inverters operate under controlled conditions to verify stability, temperature behavior, operating consistency and reliability.
Final Inspection & Packaging
Final checks cover product appearance, specifications, labels, accessories, electrical status and packaging before products are approved for shipment.
Power Inverter Testing & Production Verification
Testing parameters depend on input voltage, AC output, frequency, rated power, product configuration and target-market requirements. Production verification helps confirm electrical performance before shipment.
