A manufacturing method of touchpad device, comprising:
- (a) providing a light-curing plate, wherein the light-curing plate comprises a first release sheet, a second release sheet, and a light-curing adhesive film stacked with each other;
- the light-curing adhesive film is in an uncured state and comprises a first surface and a second surface opposite to the first surface, the first release sheet is attached to the first surface, and the second release sheet is attached to the second surface;
- (b) removing the first release sheet and attaching the first surface of the light-curing adhesive film to a surface of a touchpad;
- (c) illuminating the light-curing adhesive film with a light emitted by a light-emitting element and removing the second release sheet;
- (d) attaching a surface of a circuit board to the second surface of the light-curing adhesive film by a machine tool;
- and
- (e) reacting the light-curing adhesive film from the uncured state to a cured state.
