A method and apparatus for producing timing signals for an ultra wideband pulse generator are provided. The method may comprise obtaining a temperature reading from a first temperature sensor in the fan speed control system during a first time period. The intermediate wiring board has angled-away external flat conductors, which are electrically connected in the contact terminal areas of the wiring board. A dimension of the spacer between the carbon nano-tube and the conductor is efficiently controlled by adjusting its width.
