1. A resin-sealing apparatus that carries a sheet-shaped resin to be compression molded and a workpiece having an electronic component mounted on a plate-shaped member into a sealing mold, and performs compression molding, the resin-sealing apparatus comprising:
a workpiece measuring unit that measures a thickness of the workpiece;
a resin supply part that supplies the sheet-shaped resin to be compression molded by cutting out an appropriate amount of sheet-shaped resin to be compression molded into a predetermined shape corresponding to a measuring result of the workpiece measuring unit without redundancy or deficiency for one-time compression molding from a long resin sheet formed to have a predetermined thickness depending on an amount of resin required for each workpiece;
a measurement stage is arranged on an upstream side of the sealing mold that measures an amount of sheet-shaped resin to be compression molded that is cut out by the resin supply part before the sheet-shaped resin to be compression molded is carried into the sealing mold, wherein after a measurement, the whole sheet-shaped resin to be compression molded is completely discarded in a case that the sheet-shaped resin to be compression molded is measured to be out of a range of the appropriate amount and another sheet-shaped resin to be compression molded is supplied by the resin supply part before the sheet-shaped resin to be compression molded is carried into the sealing mold; and
a transport part that transports the appropriate amount of sheet-shaped resin to be compression molded supplied by the resin supply part to the sealing mold.
