Production apparatus for manufacturing sensor package structure

A production apparatus for manufacturing a sensor package structure, comprising:

• a first workbench for carrying a plurality of light-filtering sheets, wherein an inner surface of each light-filtering sheet contacts the first workbench;
• a second workbench for carrying a plurality of pressure-sensitive adhesive sheets;
• a third workbench for carrying a plurality of sensing dies, wherein each sensing die has an active surface exposing from the third workbench;
• and
• a shifting member configured to move along the first, second, third workbenches in sequence;
• wherein when the shifting member moves from the first workbench to the second workbench, the shifting member takes at least one light-filtering sheet to adhere to at least one pressure-sensitive adhesive sheet;
• when the shifting member moves from the second workbench to the third workbench, the shifting member takes the combination of the light-filtering sheet and the pressure-sensitive adhesive sheet to separate from the second workbench for adhering to at least one sensing die, thereby manufacturing a sensor package structure;
• wherein the sensor package structure comprises:
• a sensing die having an active surface, wherein the active surface has a sensing region and a connecting region surrounding around the sensing region;
• a light-filtering sheet having an inner surface and an opposite outer surface, wherein a periphery contour of the sensing die is greater than or equal to a periphery contour of the light-filtering sheet;
• and
• an annular pressure-sensitive adhesive sheet having two opposite adhesive surfaces and defining an opening, wherein the adhesive surfaces of the pressure-sensitive adhesive sheet are respectively pressed to seamlessly adhere to the connecting region of the sensing die and the inner surface of the light-filtering sheet, and the sensing region faces the inner surface of the light-filtering sheet via the opening;
• wherein the sensing region of the sensing die is sealed by the pressure-sensitive adhesive sheet and the light-filtering sheet.
