Abstract
There is provided a resin-sealing apparatus that supplies an appropriate amount of sheet-shaped resin for each workpiece, thereby improving the molding quality of a molded product without production of resin dust, such that no redundant resin is produced on a molded product. The resin-sealing apparatus includes a resin supply part that supplies a sheet-shaped resin by cutting out an amount of sheet-shaped resin appropriate for one-time compression molding from a long resin sheet formed to have a predetermined width and a predetermined thickness depending on an amount of resin required for each workpiece, and a transport part that transports the appropriate amount of sheet-shaped resin supplied by the resin supply part to a sealing mold.
Claims11
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.
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 by a predetermined length 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 width and 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.
A resin-sealing apparatus that carries a sheet-shaped resin to be compression molded and a workpiece having an electronic component mounted on a circular-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 by a predetermined radius 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.
