摘要： A method and apparatus for forming solder bumps by molten solder deposition into cavity arrays in a substrate immediately followed by solidification of molten solder such that precise replication of cavity volumes is consistently achieved in formed solder bump arrays. Various solder filling problems, such as those caused by surface tension and oxidation effects, are overcome by a combination of narrow molten Solder dispense slots and solidification of dispensed molten solder.
