Patent ID: 7053011

Claim:
A method of fabricating passive electronic components formed from a substrate having opposed first and second major surfaces carrying respective first and second mutually spaced-apart electrical conductors arranged lengthwise in spatially aligned different pairs of one first electrical conductor and one second electrical conductor, and including electrically conductive interconnects between the spatially aligned different pairs of first and second electrical conductors, comprising: applying laser-ablative coatings to the opposed first and second major surfaces of the substrate; directing for incidence on the substrate an ultraviolet (UV) laser beam having a spot size and an energy distribution sufficient to remove the laser-ablative coating from selected regions of the first and second major surfaces; aligning and imparting relative motion between the laser beam and each of multiple ones of the spatially aligned pairs of first and second electrical conductors to remove sufficient amounts of the laser-ablative coatings to expose the first and second electrical conductors along their lengths; breaking the substrate into multiple rowbars, each having side margins along which run different spatially aligned pairs of first and second electrical conductors; and applying an electrically conductive material along the side margins of the rowbars to form electrically conductive interconnects between the spatially aligned pairs of first and second electrical conductors.
