Quality Manufacturing

Standardized 9-Step Power Supply Assembly Workflow

From component level inspection to crated export shipments, each power unit moves through nine rigid quality-controlled stages to ensure zero-defect delivery.

Step 01

Raw Materials IQC

100% incoming electrical and parametric inspection of electrolytic capacitors, IC controllers, MOSFETs, magnetic cores, and bare PCBs.

Step 02

High-Precision SMT

Automated high-speed pick-and-place lines mount SMD components onto circuit boards followed by multi-zone nitrogen reflow ovens.

Step 03

Component Inserting

Robotic axial/radial automatic inserting combined with skilled manual placement for power transformers, heatsinks, and inductors.

Step 04

Wave Soldering & Touch-Up

Dual-wave lead-free soldering followed by selective hand-soldering and optical solder-joint inspection for mechanical stability.

Step 05

Voltage Calibration & Tuning

Precision potentiometer adjustment and feedback trimming to achieve tight output tolerance within ±1% across specified loads.

Step 06

Chassis Mechanical Assembly

Enclosure mounting, internal thermal pad positioning, insulation barrier installation, and terminal block torque locking.

Step 07

100% Full-Load Burn-In

Elevated temperature aging chambers run every unit at full rated current for 2 to 4 hours to eliminate early component failure.

Step 08

Final Functional & Hi-Pot Testing

Automated test systems log key parameters: insulation hi-pot withstand, ripple & noise, dynamic load response, and safety cut-offs.

Step 09

Automated Packaging & OQC

Laser/thermal serial barcode labelling, moisture-proof bagging, impact cushioning, and heavy-duty 5-ply export carton packaging.

Machinery & Automation

High-Capacity Industrial Machinery in Our Workshops

Continuous investment in automation minimizes human assembly variance, accelerates volume production, and maintains strict repeatability for OEM orders.

Lead-Free Wave Soldering System

Computer-controlled temperature zones ensure optimal soldering profiles without thermal shock to sensitive ICs.

Automatic Inserting Machine

High-speed automatic insertion of discrete components with integrated polarity verification and lead cutting.

SMT High-Speed Mounter

Micron-precision positioning of chips, microcontrollers, and low-profile magnetic SMD components.

Automatic Double Liquid Glue Potting

Bubble-free resin and silicone dispensing for IP67/IP68 waterproof LED power supplies and ruggedized DC-DC units.

Automated Cartoning Machine

Rapid carton erection, product insertion, and uniform case sealing to prepare pallets for global sea and air logistics.

Continuous Power Supply Assembly Line

Ergonomic ESD-safe conveyor stations with balanced takt times ensure timely delivery for contracts of up to 100,000+ units.

SMT Modular Assembly Line

Fully automated loader, stencil printer, reflow oven, and AOI inspection connected via smema interface.

Automatic Barcode Labelling Station

Precision label applicator for product serial codes, QR identification, customer OEM branding, and warning ratings.

Chassis Riveting & Screw Fastening

Preset electric screwdrivers and automatic feed mechanisms guarantee consistent housing fastening without stripped threads.
