SOUOP applies quality control throughout the complete manufacturing process, covering incoming materials, component inspection, production monitoring, assembly, functional testing, aging tests and final inspection. Products are checked at different stages before shipment to verify electrical performance, safety, functionality and overall product condition. Quality control procedures are also adjusted according to different product models, customer requirements and target markets.

Incoming Material Inspection: Key components and materials are inspected before entering production to check specifications, appearance and basic quality requirements.

Production Process Control: Quality checks are carried out during SMT processing, PCBA assembly, product assembly and other production stages to identify issues before final assembly.

Functional & Performance Testing: Finished products are tested for key functions, charging and discharging performance, output performance, interfaces and other product-specific requirements.

Aging & Reliability Testing: Aging tests and related performance checks are conducted to evaluate product stability before products proceed to final inspection and shipment.

Final Inspection: Products undergo final checks covering functionality, appearance, accessories, labeling, packaging and other order requirements before delivery.

Certification & Compliance Support: Products can be tested and certified according to applicable market and customer requirements, including areas such as electrical safety, electromagnetic compatibility and environmental compliance.
