Direct Write technology for high voltage & high value thick film resistors
Micropenning, a “direct write” technology, is Exxelia Ohmcraft’s proprietary technique for manufacturing its family of resistors. This proprietary technique allows for the deposition of thick film resistor material with higher fidelity, accuracy, repeatability, and thickness control than can be achieved by other printing techniques.
The “Micropenning” process can print lines down to a few mils in width with smoother edges and greater thickness accuracy than screen printing. This provides design engineers with unmatched capability and design options – long, narrow traces without neck downs allow for longer pattern lengths in smaller packages. Exxelia Ohmcraft resistors made using lower resistivity ink in combination with a higher aspect ratio design can significantly improve electrical performance. This allows for equivalent resistors to be produced in smaller packages with higher voltages and/or higher resistances.
Improved electrical performance
The paramount features of Exxelia Ohmcraft’s resistor products are the very high voltage ratings achievable in a given package size and the very low current noise attainable in very high resistance values.
