Abstract: The present invention provides a method for determining multiple touch inputs on a resistive touch screen, the method comprises determining a touching sequence between a first object and a second object when the first object and the second object touch the resistive touch screen respectively; calculating coordinate of a first point and coordinate of a actual point according to voltage drop in the resistive touch screen meanwhile the first object keeps touching the resistive touch screen; and determining a control instruction according to movement of the actual point.

Abstract: A method of fabricating a polymer resistor in an interconnection via in a printed circuit board includes forming a plurality of first conductive traces on a substrate, forming an interconnection via through one of the first conductive traces in the substrate and terminating at a second conductive trace, filling polymer resistor paste in the interconnection via so as to contact the second conductive trace, thermally treating the polymer resistor paste to produce a polymer resistor, and forming a conductive layer in contact with the resistor and the one first conductive trace.
