Abstract: A photolithographically patterned spring contact is formed on a substrate and electrically connects contact pads on two devices. The spring contact also compensates for thermal and mechanical variations and other environmental factors. An inherent stress gradient in the spring contact causes a free portion of the spring contact to bend up and away from the substrate. An anchor portion remains fixed to the substrate and is electrically connected to a first contact pad on the substrate. The spring contact is made of an elastic material and the free portion compliantly contacts a second contact pad, thereby electrically interconnecting the two contact pads.

Abstract: A method and apparatus is provided which compensates for environmental factors which cause misdirection of ink drops ejected from an ink jet printhead. Ink drops are electrostatically accelerated in a direction perpendicular to a print substrate, decreasing the ink drop flight time from the printhead to print substrate. The decrease in flight time decreases the misdirecting effect of the environmental factors on the ink drops since the environmental factors act on the ink drops for a shorter amount of time. Accelerating the ink drops also increases the spot size created when the drop impacts the print substrate, decreasing the amount of ink needed to create an image on the print substrate. The decrease in ink use results in less cockle and curl in the print substrate. The device also provides electrostatic deflection of the ink drops in directions parallel to the print substrate, increasing the resolution of the printhead.
