We are China Coil circuit boards factory, sometimes referred to as RF coil or spiral coil boards, refer to a design where a single trace coils around itself in a spiral-like pattern. These Coil PCB designs have gained popularity as onboard planar inductors, instead of using a physical inductor component to save space and money. In the past, the technique was used extensively for IR receivers advanced Coil PCB but notably gained popularity when a designer used multiple coils in a multi-layer PCB to create a miniature PCB motor.
China PCB coil is an inductor created directly on the layers of a printed circuit board using the copper traces themselves to form the coiled structure. Wholesale Coil PCB allow embedding inductive elements into the circuit board itself rather than using discrete inductor components. The trace dimensions and layout pattern determine the resulting inductance.
