Quality Product Manufacturing
PCBA Production
PCBA manufacturing is a core electronic manufacturing process for electrical products. It begins with component preparation and bare board processing, followed by SMT automated processes (printing, mounting, and reflow soldering) and THT wave soldering to complete the soldering of all components. Finally, qualified circuit boards undergo cleaning and are coated with conformal coating to ensure the removal of residues and enhance the board’s moisture and corrosion resistance.
PCBA Testing & Calibration
This stage is a crucial step in enabling the meter to achieve accurate measurement capabilities. It first involves firmware programming, followed by software adjustments and writing of calibration coefficients on a professional calibration bench to bring the energy error to national standards. Finally, it verifies all electronic functions, including communication, power supply, and control, ensuring the PCBA (Power Control Analyzer) is fully qualified.
Semi-finished Product Assembly
The calibrated PCBA is physically integrated with all mechanical and functional components, including the casing, display screen, battery, and terminals, to form a complete finished meter. The entire unit is then powered on and tested to verify that all components (such as relays, buttons, and displays) work together and function correctly.
Burn-in Test
Finished electric products must undergo a continuous power-on aging test for 48 to 72 hours. As the final reliability screening before leaving the factory, this test accelerates the exposure of potential defects by simulating harsh environments such as high and low temperature cycles, thereby ensuring that the electrical products have a high standard of stability and accuracy during their actual service life of more than ten years.
Final Quality Assurance & Inspection
Following the aging tests, the products undergo a final verification of metrological accuracy and a thorough visual inspection. This serves as the ultimate Quality Assurance gate to screen out any non-conforming or functionally defective units before packaging.
Labeling & Shipment
The final stage involves affixing essential product identification labels to all qualified finished units to guarantee traceability and regulatory compliance. Following labeling, the meters are securely packaged for protection against transit damage, and the batch is prepared for shipment and final delivery to the customer.
Quality Control Process
Quality Control Process of the Raw Materials: All incoming raw materials are inspected, including metering chips, MCUs, PCB boards, current transformers/relays, enclosures, and terminals, etc.
Quality Control in the Production & Assembly Process: Inspection is integrated into every critical stage of the manufacturing process, covering key steps such as SMT, wave soldering, meter assembly, final metrology calibration, and aging testing.
Quality Control Process for the Final Products: All products are 100% inspected before the order is packaged. We will make sure every detail, including size, safety performance (withstand voltage, insulation), final measurement accuracy, appearance integrity, labeling, function, etc.
