Abstract:
1. A sensing device comprising: a substrate for attachment to a surface of a target object using a bonding material, the substrate comprising a first side and a second side; one or more sensing elements located on the substrate; one or more bonding material vias extending from the first side of the substrate to the second side of the substrate, wherein the bonding material vias are configured to allow the bonding material to flow from the second side of the substrate to the first side of the substrate and form bonding rivets on the first side of the substrate; and at least one layer on the first side of the substrate forming a window around each of the one or more bonding material vias and limiting the flow of the bonding material across the first side of the substrate within the window, wherein the at least one layer includes a material selected from the group consisting of polyimide, glass reinforced polyimide, copper, plating, electrolysis nickel over immersion gold, polyester, polyethylene naphthalate, and polyetherimide.
