A electronics processing factory in Humen, Dongguan, has newly installed two high-speed SMT production lines. Even during the equipment commissioning phase, power supply issues became apparent. Frequent start-stop cycles of injection molding machines around the plant caused instability in the external grid voltage, with fluctuations exceeding the permissible operating range of the placement machines. The equipment intermittently triggered servo fault alarms, component placement positions shifted, and the defect rate remained high throughout the trial production phase.

The company compared multiple power supply suppliers and ultimately selected Dongguan voltage stabilizer manufacturer – Dongguan Jinbao Electromechanical Co., Ltd. – to undertake this power supply supporting project.

Engineers were stationed at the plant to continuously collect workshop voltage operation data over 72 hours. Taking into account the instantaneous start-up current and voltage regulation accuracy requirements of the high-speed placement machines, they customized a dedicated voltage stabilizer solution for the SMT equipment. As a provincial-level "Specialized and Sophisticated" enterprise, Jinbao Electromechanical leverages more than fifty patented technologies in the power supply field. Its voltage stabilizers are equipped with a high-precision closed-loop sampling control system, ensuring output accuracy is stably controlled within ±1%, with millisecond-level response speed to quickly counteract voltage surges from the external grid.

Equipment delivery, wiring, and power-on commissioning were completed in a single seamless process. Since going live, the SMT production lines have experienced no downtime or placement shifts caused by voltage fluctuations, and the yield rate has returned to normal levels.

From this project, it is clear that imported high-speed placement machines should not be directly connected to regular mains power. Proper voltage stabilization planning at the early stage can fundamentally reduce later costs associated with expensive equipment repairs and product rework.
