Reel diameters ranging from 254 mm to 292 mm also exist. Commonly used hub diameters are 80, 100, 150, and 178 mm. 2 For reels greater than or equal to 360 mm diameter (A), various sizes exist with the most widely used being 381 mm 2 mm, 482 mm 2 mm and 558 mm 2 mm. Hub diameters vary widely, up to 254 mm. 3 Tape with components must wrap around hub without damage. EIA-481-B Page 16 Left Intentionally Blank. EIA-481-B Page 17 Addendum Complementary taping standards: EIA-7268 mm Punched & Embossed Carrier Taping of Surface Mount Components for Automatic Handling of Devices Smaller Than 2.0 mm x 1.2 mm EIA-747Adhesive Backed Punched Plastic Carrier Taping of Singulated Bare Die and Other Surface Mount Components for Automatic Handling of Devices Generally Less Than 1.0 mm Thick EIA-763Bare Die and Chip Scale Packages Taped in 8 mm & 12 mm Carrier Tape for Automatic Handling Recommendation: For waste minimization purposes it is recommended that the industry modify its methods and equipment so that the minimum leader dimension can be eventually reduced from 400 mm to 320 mm and that the minimum trailer dimension be reduced from 160 mm to 80 mm.
