A method for preparing flat-top pads in electronic components includes the steps of: a) stencil printing a flat-top deposit of a curable silicone composition onto a first electronic substrate, where the first electronic substrate is selected from a semiconductor die or a semiconductor die attachment member, where stencil printing the flat-top deposit is performed by squeegee through a down-step stencil; b) curing the flat-top deposit to form a flat-top pad; optionally c) adhering a second electronic substrate to the top of the flat-top pad, where the second electronic substrate is selected from a semiconductor die or a semiconductor die attachment member; and optionally d) repeating steps a), b) and c).
