Portable space heaters are small, electric resistance heating units. Regardless of the shape, size or type of electric heating element found in an electric space heater, virtually all power drawn is converted into heat. The cost of operating an electric heater depends on how much heat the unit is delivering.ortable space heaters are small, electric resistance heating units.

Flexible electronics, also known as flex circuits, is a technology for assembling electronic circuits by mounting electronic devices on flexible plastic substrates, such as polyimide, PEEK or transparent conductive polyester film.
As an interconnect, the main advantages of flex over traditional cabling are greater reliability, size and weight reduction, elimination of mechanical connectors, elimination of wiring errors, increased impedance control and signal quality, circuit simplification, greater operating temperature range, and higher circuit density. flexible printed circuit â Flex circuit . Abbreviated FPC or FC. flip-chip âA mounting approach in which the chip ( die ) is inverted and connected directly to the substrate rather than using the more common wire bonding technique.
