发明名称 Mold transfer apparatus and method
摘要 The present invention relates generally to a new mold transfer apparatus and method. More particularly, the invention encompasses an apparatus that is used to form metallic interconnections, such as, for example, solder connections, such as, solder balls or solder columns, using a mold that is already filled with transferable metallic material. However, these metallic interconnections in a mold could also be used to form other structures, such as, for example, heat sinks with fins, etc.
