    摘要: A method for constructing a composite solder transfer moldplate for flip chip wafer bumping of a substrate, comprising the steps of coating at least one polymer layer onto a first side of a transparent plate, the plate having a thermal expansion coefficient similar to that of the substrate; and forming a multiplicity of cavities in a polymer layer on one side of the plate, each cavity being for receiving solder. A moldplate made by the method. The structure has required behavior through temperature excursions between room temperature and various solder molten temperatures.
