    Abstract: An apparatus and a method is described to provide a printed wiring board which includes a substrate (10) having electrical contact pads (12) disposed over a surface of the substrate, with the contacts having a patterned solder mask (14) with an aperture (14') that exposes less than the entire surface of the electrical contact pads (12). Thus by providing a soldermask aperture (14') that exposes less than the entire surface of the contact (12), the aperture (14') can be used to completely contain liquid solder material (16) from the solder reflow attach operation.

    Abstract: In an example embodiment, a circuit interconnect includes a first printed circuit board (PCB), a second PCB, a spacer, and an electrically conductive solder joint. The first PCB includes a first electrically conductive pad. The second PCB includes a second electrically conductive pad. The spacer is configured to position the first PCB relative to the second PCB such that a space remains between the first PCB and the second PCB after the first electrically conductive pad and the second electrically conductive pad are conductively connected in a soldering process. The electrically conductive solder joint conductively connects the first electrically conductive pad and the second electrically conductive pad.
