Claim:
1. A method of manufacturing a dual in-line memory module (DIMM) connector system, comprising a motherboard, a DIMM card and a connector by which the DIMM card is coupled with the motherboard, the method comprising: selecting, as a printed circuit board (PCB) material for the motherboard, FR4061 as a mid-loss dielectric constant material; thinning signal pads of the motherboard to be about 25% as wide as ground pad of the motherboard or thinning signal pads of the DIMM card to be about 25% as wide as ground pads of the DIMM card; modifying distal ends of the signal pads of the motherboard to comprise flat edges and a single convex curved edge terminating at the flat edges; disposing the ground pads of the motherboard proximate to the signal pads of the motherboard; connecting signal vias to distal edges of the signal pads of the DIMM card, the signal vias having surface mounts (SMTs) extending therefrom and the SMTs having single angular portions; and forming shared antipads of the motherboard to be rectangular and forming shared antipads of the DIMM card to be elliptical.
