Abstract:
1. A multilayer package comprising: a first substrate including: a second substrate including: a third substrate including: a first adhesive film disposed between the first substrate and the third substrate and having an aperture located at least in part between the first and third conductive pads, the first adhesive film mechanically bonding the first substrate and the third substrate; a first solder segment occupying at least a substantial portion of the aperture in the first adhesive film and providing an electrical connection between the first conductive pad and the third conductive pad, the first solder segment being formed at least in part by a reflow of solder paste applied to at least one of the first conductive pad and third conductive pad; a second adhesive film disposed between the second substrate and the third substrate and having an aperture located at least in part between the second and fourth conductive pads, the second adhesive film mechanically bonding the second substrate and the third substrate; a second solder segment occupying at least a substantial portion of the aperture in the second adhesive film and providing an electrical connection between the second conductive pad and the fourth conductive pad, the second solder segment being formed at least in part by a reflow of solder paste applied to at least one of the second conductive pad and fourth conductive pad.
