摘要: A process and tools for forming and/or releasing metal preforms, metal shapes and solder balls is described incorporating flexible molds or sheets, injection molded metal such as solder and in the case of solder balls, a liquid or gaseous environment to reduce or remove metal oxides prior to or during metal (solder) reflow to increase surface tension to form spherical or substantially spherical solder-balls.
