Factory Tour: Manufacturing Excellence
Beauty STC’s manufacturing facility in Jiangmen, Guangdong Province, serves as a key production hub for our LED lighting solutions, strategically positioned within the Pearl River Delta for efficient logistics and access to skilled labor. The factory is modern, ISO 9001 certified, and designed specifically for high-volume, precision LED assembly with stringent quality control protocols integrated throughout the production flow.
Our surface mount technology (SMT) line forms the core of PCB assembly for LED products. It features multiple high-speed Yamaha YS series placement machines, including models like the YSM20 and YSM10, capable of handling ultra-fine pitch components down to 0201 metric size and complex LED packages. These machines operate at speeds exceeding 100,000 components per hour while maintaining exceptional placement accuracy, critical for dense LED arrays and miniature drivers. The line is supported by advanced automated optical inspection (AOI) systems after placement and solder paste printing, alongside nitrogen-reflow soldering using Heller ovens to ensure void-free, high-reliability solder joints essential for thermal management in LED applications. This SMT capability allows us to efficiently produce the complex driver and LED module PCBs required for various lighting products, including flexible strips.
Rigorous aging and reliability testing are non-negotiable at our Jiangmen facility. We operate a dedicated aging test area equipped with multiple large-scale environmental chambers capable of continuous operation. Finished LED products, particularly strips and modules, undergo mandatory burn-in tests at elevated temperatures, typically 60-70°C, for a minimum of 24 hours, though 48-72 hour cycles are standard for premium lines and customer-specific requirements. These chambers incorporate real-time monitoring systems that track and log critical parameters like forward voltage, current draw, and luminous output throughout the aging period. Any units exhibiting parameter drift beyond our tight tolerances or failure during this extended stress test are automatically rejected, ensuring only units with proven early-life reliability reach customers. This process significantly reduces infant mortality rates in the field.
