  • Method of Creating Molds of Variable Solder Volumes for Flip Attach
    Publication number: 20090004840
    Abstract: A method for fabricating a solder transfer mold includes masking a substrate with a masking agent. A pattern is transferred to the substrate mask. The masked substrate is etched until cavities of a first volume are formed. The cavities of the first volume are selectively coated. The masked substrate is etched until cavities of a second volume are formed.
