    Abstract: This invention provides an evaluation board for evaluating one or more aspects of a surface mount technology system. In one aspect, the evaluation board has a substrate with at least one surface. A plurality of board pad patterns, each including a plurality of board pads, is formed on the surface. The different board pad patterns may have different shaped, sized and spaced board pads, allowing the characteristics of a surface mount technology to be tested on some or all of the board pad patterns at the same time and under uniform conditions. In another aspect, the surface may have a plurality of area-filled board pads similarly allowing a surface mount technology to be tested on the various area-filled board pads.
