The height of the wire columns is substantially uniform for the plural groups of wire columns, and a length of at least one of the wire columns is greater than the uniform height. A method of fabricating an electronic device package having a column grid array includes applying two templates on wire columns of the column grid array and bending at least one wire column to increase its length while maintaining a uniform height for the column grid array. In another aspect, an electronic device package substrate includes wire columns having at least one non-uniformity in lengths of the columns, and the length of a wire column corresponds to a distance of that wire column from the neutral stress point of the substrate. The non-uniformity of length in the wire columns reduces stress in the package leads after attachment of the package to a carrier substrate, such as a printed circuit board."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Isostress grid array and method of fabrication thereof","description":"An electronic device package includes a substrate and wire columns arranged in groups about a neutral stress point of the substrate.
