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.
Claims17
An evaluation board for evaluating one or more aspects of a surface mount technology system, the board comprising:
- a) a substrate having a surface;
- b) a plurality of board pad patterns formed on the surface, wherein each of the board pad patterns includes a plurality of board pads;
- and wherein at least some of the board pad patterns are arranged in a matrix wherein the size of board pads in adjacent board pad patterns progressively changes.
An evaluation board for evaluating one or more aspects of a surface mount technology system, the board comprising:
- a) a substrate having a surface;
- b) a plurality of board pad patterns formed on the surface, wherein each of the board pad patterns includes a plurality of board pads;
- and wherein at least some of the board pad patterns are arranged in a matrix wherein the pad-to-pad spacing of board pads in adjacent board pad patterns progressively changes.
An evaluation board for evaluating one or more aspects of a surface mount technology system, the board comprising:
- a) a substrate having a surface;
- b) a plurality of board pad patterns formed on the surface, wherein each of the board pad patterns includes a plurality of board pads;
- and wherein at least some of the board pads patterns are arranged in a two dimensional matrix having rows and columns of board pad patterns, and wherein in each row of the matrix, a first characteristic of the board pads in the board pad pattern is varied and wherein in each column of the matrix, a second characteristic of the board pads in the board pad patterns is varied.
An evaluation board for evaluating one or more aspects of a surface mount technology system, the board comprising a substrate having two surfaces, wherein each surface has a plurality of board pad patterns formed on it, each board pad pattern comprising at least one board pad;
- wherein at least some of the board pad patterns are arranged in a matrix wherein at least one of the size and the pad-to-pad spacing of board pads in adjacent board pad patterns progressively changes.
An evaluation board for evaluating one or more aspects of a surface mount technology system, the board comprising:
- a) a substrate having a surface;
- b) a plurality of board pad patterns formed on the surface, wherein each of the board pad patterns includes one of:
- an area-filled board pad or a plurality of board pads;
- wherein at least some of the board pad patterns are arranged in a matrix wherein at least one of the size and the pad-to-pad spacing of board pads in adjacent board pad patterns progressively changes.
An evaluation board for evaluating one or more aspects of a surface mount technology system, the board comprising:
- a) a substrate having a surface;
- b) a plurality of board pad patterns formed on the surface, wherein each of the board pad patterns includes an area-filled board pad;
- and wherein at least some of the board pad patterns are arranged in a matrix wherein the size of area-filled board pads in adjacent board pad patterns progressively changes.
An evaluation board for evaluating one or more aspects of a surface mount technology system, the board comprising:
- a) a substrate having a surface;
- b) a plurality of board pad patterns formed on the surface, wherein each of the board pad patterns includes an area-filled board pad;
- and wherein at least some of the board pad patterns are arranged in a matrix wherein the pad-to-pad spacing of area-filled board pads in adjacent board pad patterns progressively changes.
