Abstract
A tape reel according to an embodiment of the present technology includes: a cylindrical reel hub that includes an outer periphery portion, a tape being wound on the reel hub. The reel hub is formed of a material in which a deformation amount when a load of 300 N is applied radially inward to an axial center of the outer periphery portion is 0.3 mm or less and a water absorption rate is 0.1% or less.
Claims16
A tape reel, comprising:
- a cylindrical reel hub that includes an outer periphery portion, a tape being wound on the reel hub, wherein
- the reel hub is a molded body of a composite material in which an inorganic filler is contained in a polyphenylene sulfide resin and in which a deformation amount when a load of 300 N is applied radially inward to an axial center of the outer periphery portion is 0.165 mm to 0.3 mm and a water absorption rate is 0.1% or less,
- wherein the composite material having a flexural modulus of 20 GPa or more,
- wherein the inorganic filler is at least one of a glass filler, a mineral filler, or a carbon filler, and
- wherein an amount of the inorganic filler ranges from 30 wt % to 65 wt %.
