Coil printed circuit boards
Coil pcbs are also known as RF coil or spiral coil boards, refer to a design where a single trace coils around itself in a spiral-like pattern. Coil PCBs are often manufactured with round, square, or meander form of turns, although they can be in a polygon form. With PCB development technology, multiple coils are used in a multilayer PCB and gain great success.
