发明名称 Variable pitch IC bond pad arrangement
摘要 The bond pads (22) for a ceramic package (10) are deposited on the pre-fired ceramic at variable pitch with the bond pad widths (47) increasing as a function of the distance (49) of each pad from an alignment point (40), whereby bond pads at the extremity (36) of the package have the largest pad width and pads toward the alignment point (40) of the package have the narrowest width.
