1. Ceiling Fan
Our custom FR‑4 PCBs serve as the core control board for ceiling fans. They handle fan speed regulation, forward/reverse rotation switching, and motor protection functions.Featuring high mechanical strength and reliable temperature resistance, these PCBs deliver stable long‑time operation for household and commercial ceiling fan equipment.
2. Induction Cooker
For induction cookers, the FR‑4‑based PCB undertakes power drive, temperature sensing, over‑heat protection and user interaction signal processing.
With excellent flame‑retardant and heat‑dissipation performance, it adapts to the high‑temperature working environment of kitchen heating appliances
and guarantees safe & consistent cooking performance.
3. Radio Drilling Machines
In radio drilling machines, the custom mini CNC FR‑4 PCB controls motor drive, signal receiving, sensor feedback and working‑status monitoring.
Compact layout design fits limited internal device space, supporting precise, continuous operation for industrial drilling equipment.
