Facility & Technical Capabilities
Integrated In-House Engineering & Production
At Dongguan Cevra Electronic Technology Co., Ltd., we provide full-lifecycle turnkey manufacturing for human-machine interface (HMI) controls. From initial engineering stack-up analysis and CAD rendering to precision multi-layer screen printing, high-speed automated punching, and laser die-cutting, every phase is completed inside our 2,600㎡ facility.
By keeping circuit printing, dome placement, and automated laminating under unified quality control, we eliminate subcontracting delays, guarantee strict layer-to-layer registration tolerances, and maintain lot-to-lot electrical integrity.
