Abstract: A memory card substrate includes a first solder pad assembly formed on a top edge of the memory card substrate. The first solder pad assembly has multiple first solder pads equally spaced from each other and multiple first gaps each sandwiched between two adjacent first solder pads. A second solder pad assembly is formed on a bottom edge of the memory card substrate and has multiple second solder pads equally spaced from each other and multiple second gaps each sandwiched between two adjacent second solder pads. Each first solder pad corresponds to one of the second gaps so that the first solder pads are alternately arranged on the top edge relative to the second solder pads on the bottom edge.
