## Abstract

A resin supply apparatus, a resin sealing apparatus, and a method for manufacturing a resin-sealed product are provided. A resin supply apparatus supplies a resin onto a workpiece on which elements are arranged in a first direction and a second direction intersecting the first direction, respectively. The resin supply apparatus includes: an acquisition unit for acquiring arrangement information of the elements on the workpiece; a supply unit for supplying the resin onto the workpiece; a calculation unit for calculating a resin supply pattern based on the arrangement information; and a drive unit for moving at least one of the workpiece and the supply unit relative to the other along the resin supply pattern. The resin supply pattern has linear paths extending along the first direction, and a region between the mutually adjacent linear paths in the plurality of linear paths is opened to the outside of the workpiece.

## Claims

### Claim 1

A resin supply apparatus for supplying a resin onto a workpiece on which elements are arranged in a first direction and a second direction intersecting the first direction, respectively, the resin supply apparatus comprising:
an acquisition unit configured to acquire an arrangement information of the elements on the workpiece by imaging the workpiece and analyzing the image of the workpiece;
a supply unit configured to supply a resin onto the workpiece;
a calculation unit configured to calculate a resin supply pattern by reading the registered arrangement information by the acquisition unit, and to calculate a desired moving pattern of the supply unit; and
a drive unit configured to move at least one of the workpiece and the supply unit relative to the other along the resin supply pattern,
wherein the resin supply pattern has a plurality of linear paths extending along the first direction, and
a region between mutually adjacent linear paths in the plurality of linear paths is opened to the outside of the workpiece.

### Claim 2 (depends on 1)

The resin supply apparatus according to claim 1,
wherein the plurality of linear paths extend parallel to the first direction.

### Claim 3 (depends on 1)

The resin supply apparatus according to claim 1, wherein the plurality of linear paths have a first linear path, a second linear path adjacent to the first linear path, and a third linear path adjacent to the second linear path,
the first linear path is connected to the second linear path on one end side of the first direction, and
the second linear path is connected to the third linear path on the other end side of the first direction.

### Claim 4 (depends on 1)

The resin supply apparatus according to claim 1,
wherein the resin supply pattern is one continuous linear line.

### Claim 5 (depends on 1)

The resin supply apparatus according to claim 1,
wherein at least one of the plurality of linear paths extends over a region between the elements adjacent in the second direction.

### Claim 6 (depends on 1)

The resin supply apparatus according to claim 1,

the clamped resin sealing mold has a plurality of air vents for discharging air inside the cavity between the upper mold and the lower mold.

### Claim 12 (depends on 11)

The resin sealing apparatus according to claim 11,
wherein at least one of the plurality of air vents is arranged on an extension line of a region between the mutually adjacent linear paths in the plurality of linear paths.

### Claim 13

A resin supply apparatus for supplying, onto a release film, a resin used for sealing a workpiece on which elements are arranged in a first direction and a second direction intersecting the first direction, respectively, the resin supply apparatus comprising:
