We wind with wire that most people are not able to see until hundreds of turns begin to take shape as a precise micro-coil as one can see (or not) above or in the tip of the fine point tweezers to the left.
While we have equipment capable of winding wire as large as 200-micron wire, our strength and our focus is fine and ultra-fine wire winding (10 to 50 micron) for micro-coils that demand the highest precision and quality.
