Definitions

  • Surface mount supplies carrier tape or component carrier tape is used to transport components (e.g., electrical components such as resistors, capacitors, or integrated circuits) from a component manufacturer to a different manufacturer that assembles the components into new products, typically by having automated assembly equipment sequentially remove components from the carrier tape and assemble them into to the new products.
  • components e.g., electrical components such as resistors, capacitors, or integrated circuits
  • Such carrier tape is a polymeric strip that has been formed to have wall portions defining a series of identical pockets at predetermined uniformly spaced intervals along its length, which pockets are shaped to closely receive identical components the tape is adapted to transport (e.g., which pockets could, for example, have rectangular or generally "I” or “T” shapes in the plane of the strip, and could have flat or rounded bottoms to accommodate the shape of the components), which strip normally also has through openings uniformly spaced along one side to receive a drive sprocket by which the strip can be driven and to provide indexing holes that can be used for accurately locating the pockets along the tape with respect to assembly equipment.
  • the carrier tape is manufactured in a first manufacturing location, wound on a reel and transported to the supplier of the components it is intended to transport.
  • the component supplier unwinds the carrier tape from the reel, fills the pockets along the carrier tape with components, adheres a removable cover strip along the carrier tape over the component filled pockets, winds the component filled carrier tape with the attached cover strip onto a different typically smaller reel, and sends it to the user who feeds it from the reel into the assembly equipment which removes the components.
  • combination 11 generally comprises (1) a length of component carrier tape 10 having elongate edges and a uniform width between its edges; and (2) a reel 14 including a hub 15 having an axis 16, opposite axially spaced ends and a cylindrical peripheral surface 18 between its ends, and a pair of flanges 19, one fixed to the hub 15 at each of its ends and projecting radially from the hub 15, the flanges 19 having opposed inner surfaces spaced by a distance (e.g., 76.2 millimeters or greater) significantly greater than the width of carrier tape 10.
  • a distance e.g., 76.2 millimeters or greater
  • the carrier tape 10 is unitary, can be made to have a variety of uniform widths between its edges (e.g., 8, 12, 16, 24, 32 or 44 millimeters), and is made of a thin polymeric material (e.g., any thermoplastic crystalline or non crystalline material such as polyester, polycarbonate, polypropylene, styrene, butadiene, ABS plastic, etc. in the range of about 0.012 to 0.04 centimeter thick, and typically 0.025 centimeter thick) so that it is flexible.
  • the carrier tape 10 comprises a strip like portion 22 defining a top surface for the tape 10, and wall portions defining a multiplicity of similarly shaped pockets 24 spaced along the carrier tape 10 and opening through its top surface.
  • the wall portions may or may not include anti nesting shoulders for restricting entry of side wall portions defining the pockets 24 in one wrap of the carrier tape 10 on a reel into the pockets 24 in a wrap of carrier tape 10 beneath it as is described and claimed in U.S. Patent No. 4,898,275 issued February 6, 1990, the content whereof is incorporated herein by reference.
  • the carrier tape 10 also has a conventional series of equally spaced and sized through openings 26 along one edge of the strip like portion 22 which will receive the teeth of a drive sprocket by which the carrier tape 10 may be driven through automated equipment which loads components into the pockets 24 or removes components from the pockets 24.
  • the carrier tape 10 has an opening generally centered in the bottom wall of each of the pockets 24 as is required by an industry standard to allow the presence of a component in a pocket 24 to be sensed, or to allow access for a probe that facilitates removal of a component from the pocket 24.
  • the flanges 19 of the reel 14 are compressed around their peripheries to restrict engaging the edges of component carrier tape 10 being wound onto or off of the hub 15, and may also be compressed or creased along rectangularly disposed lines 34 ending in the openings 32 to afford bending portions of the flanges 19 away from the opposite flange 19 along the lines 34 to either afford visual inspection of the amount of component carrier tape 10 remaining on the reel 14, or to reduce the diameter of the reel 14 to facilitate its disposal, preferably to a recycler of paper products.
  • Figure 5 there is illustrated one flange 19 of the reel 14 and successive wraps designated Z1 and Z2 of the component carrier tape 10 in different layers joined by one of the transition portions 20 of the component carrier tape 10 that are curved to allow those wraps Z1 and Z2 to be angled in opposite directions with respect to the axis 16 of the hub 15, and which curvature will result from cold flow in the carrier tape 10 caused by such angling in opposite directions.
  • a reel 14 that has a hub 15 diameter that is significantly above the minimum diameters indicated by the above formula, such as a reel 14 with a 355.6 millimeter (14 inch) diameter for either 8 or 12 millimeter wide component carrier tapes 10.
