WINDING REEL OF FILM CARRIER TAPE

摘要

PROBLEM TO BE SOLVED: To provide a winding reel where occurrence of abrasion powder can effectively be prevented and a shape at the time of forming can be stabilized. SOLUTION: The winding reel of a film carrier tape mounting an electronic component is provided with a shaft mounting hub, a spoke which is radially extended from the shaft mounting hub, and an outer peripheral circular part which is circularly connected to the spoke. The reel is the injection molding object of a resin composite (sum total of acrylonitrile-butadiene-styrene copolymer and carbon fiber is 100 pts.wt.) including 85 to 98 pts.wt. of acrylonitrile-butadiene-styrene copolymer and 2 to 15 pts.wt. of carbon fiber whose average fiber diameter is 0.1 to 30μm. A surface resistance value is within a range of 104to 109Ω. The ratio (LR/LB) of the interval (LB) of the spoke in the shaft mounting hub and an average interval (LR) of the outer peripheral circular part becomes within the range of 0.990 to 1.100.
