A template or mold with cavities may be pre-fabricated to hold solder paste material applied to the mold, for example with a solder paste printing process. The depth and/or diameter of the cavities may be predetermined as a function of spatial position within the mold working surface area. Mold cavity dimensions may be specified corresponding to package position to account for one or more pre-existing or expected spatial variations in the package, such as a package-level warpage measurement. Any number of different ball heights may be provided. The molds may be employed in a standardize process that need not be modified with each change in the mold."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Variable ball height on ball grid array packages by solder paste transfer","description":"BGA packages with a spatially varied ball height, molds and techniques to form such packages.
