19、ing that currently most odd form components are manually assembled to printed circuit boards, efforts were made to automate this assembly process. The resultant difculties encountered were due to inconsistencies in part packaging, feeding and presentation. Existing tape and reel standards did not ad

20、dress the scope of packaging and feeding of odd form components for automated assembly. 2 Abstract The process consists of tape packaging and tape feeding equipment, and the tapes - ali designed around the concept that a common tape package is the solution to the numerous parts feeding problems. The

21、 tape package consists of a two part tape system: A carrier tape which is prepunched with component lead registration patterns, tab patterns or precision formed pockets which act to consistently orient and locate the parts; and, a mechanically interlocking cover tape which interlocks with the carrie

22、r tape securing the parts on the tape. The tapes are mechanically unlocked and separated at the tape feeder pick point, exposing oniy one row (pitch) of parts. The mechanically interlocking carrier and cover tapes were designed and developed to provide a tape and reel technology with which to reliab

23、ly feed a wide variety of odd form parts for accelerated implementation of automated assembly. Selecting from the available tape widths, pitch lengths and part locating methods, a tape package can easily be designed for almost any small part. The technology provides the packaging and feeding solutio

24、n for both sufiace mount technology (SMT) and thru-hole technology (“) parts which heretofore could not be packaged and fed in high speed automated assembly. Thru-hole designed parts are precisely positioned and registered in the prepunched carrier tape by their leads. Precise part and lead pattern

25、positioning of THT odd forms within a tape and reel format eliminates the large space requirements, capital (e.g. vision or remote mechanical positioning), and comparatively lengthy cycle times demanded by trays. Positional uniformity of parts in the carrier tape eliminates difficulties caused by va

26、riations in part size and shape. This tape and reel technology offers improved flexibility and reiiability in the automation process quite unlike plastic tubes with varying cross sections and lengths. An anti-static foam tape may be interleaved between layers as thru-hole parts are wound onto the su

27、pply reel during packaging. This foam interleave tape provides protection of the leads of th-hole parts - the anti-static tape is easily and automatically removed by a function of the feeder prior to tape guide entry. Surface mount designs of odd form parts can also be packaged and fed on tape and r

28、eel using this same process. Since the mechanically interlocking cover tape can loop over the parts and lock at several locations across the width of the carrier tape, a shallow formed pocket may be used to contain and locate the parts; orientation can be controlled by designing features of the pock

29、et which only allow parts to be packaged in a singular directiodonentation. As with THT, the cover Previous page is blank EIA/ACH-2000 Page 6 tape which secures the part provides a strong mechanical interlock and robust tape package, permitting the packaging of heavy parts such as magnetics. The sha

30、llow or semi-pocket carrier tape contains the lower portion of the part where lead coplanarity is protected. The upper portion of the part which protrudes above the pocket is available for convenient placement device or robotic end-effector access as weil as component presence sensing. Holes can be

31、provided in the carrier tape through which locator pins on the feeder can precisely locate parts for duect assembly, or hold parts in position prior to removal. The cover tape is mechanically unlocked reliably and separated from the carrier tape at the pick point by a device on the tape feeder, thus

32、 eliminating any of the potential problems caused by adhesives or heat sealing. Peel force testing is eliminated. In contrast to fll depth pockets, shallow pockets facilitate the use of thinner and narrower carrier tape, as weli as shorter pitches resulting in more parts per reel at lower cost. Semi

33、-pocket carrier is more cost effective to manufacture, handle, store, ship, and dispose of because of its dense characteristics - minimized pocket volume per part and is, therefore, lower in cost when compared to fi depth pockets. Still another tape combination configuration is used for very low pro

34、ile parts. The mechanically interlocking cover tape used in this application lays over the pocket and part, and does not loaP over the part. This configuration has all the benefits of the mechanical interlock plus the added capability to feed on standard OEM tape feeders on existing installed base p

35、ick and place equipment. The two tapes are separated by a wedge-like device, provided at no charge, which is permanently attached to the feeder with two screws. It does not need to be removed in order to feed heat seal or adhesively attached cover tapes. Further, the development of mechanically inte

36、rlocking tapes provides a reliable and rugged tape system with unlimited shelf lXe. The mechanical interlock is unaffected by temperature and humidity and may be opened and re-interlocked repeatedly without degradation. Each individuai pitch is separately and independently interlocked across the wid

37、th of the carrier tape. The durable package allows for usage of large diameter supply reels or large volume fan fold containers to provide sufficient line inventory in the automation process, thus minimizing manual intervention for inventory replenishment. Mechanically interlocking tapes offer an im

38、proved method of tape and reel or fan fold packaging and handling of both THT and SMT devices. This new technology complements certain widths of adhesive cover tape presently used to contain devices and simplifies the automated handiing of components in both the packaging and board assembly processe

39、s that use a tape and reel or fan fold format. Staple splicing of the tapes occurs while tapes continue to feed, both at the taping and feeding location, thus maximizing thruput. This results in significantly lower overall costs due to the elimination of scrap (waste generated by frequent insufficie

40、nt tape on the input supply reel to make a fll output reel), and increased taping equipment uptime (no purging and rethreadmg the STD-EIA ACH-200-ENGL 1778 3234b00 Ob1224b 577 9 EWACH-2000 Page 7 machine to put on a new input supply reel). This is of particular importance for filly automated taping

41、equipment. 3 Scope This document outlines the dimensional specifications of certain mechanically interlocking carrier and cover tapes. Mechanically interlocking cover tapes are designed to be compatible with fourteen (14) widths of carrier tape which are manufactured to precise standards. The widths

42、 of carrier tape presently available range from 38mm to 152mm and are described herein. Mechanically interlocking tapes are covered by patent numbers 4,757,895 and 4,583,641; other patents pending. 4 Description Carrier tape (Fig. 1) is joined to the mechanically interlocking cover tape (Fig. 2) usi

43、ng a fork-like tool which pushes a set of locking tabs of the cover tape into the receiving holes in the carrier tape. This creates mechanical interlocks at predetermined positions across the width and between each pitch of the carrier tape. The available component area, both minimum and maximum, is

44、 outlined in Fig. 3. Typical components (THT) are shown in Fig. 4 and are precisely registered in the there is no component movement in X,Y, theta or tilt. A top cover tape is not used, thereby avoiding problems of component displacements during peelback, while leaving components accessible for insp

45、ection, testing, maiking and other processing by automated means. SURFTAPE is intended for use with extremely small, light-weight, and delicate SMCs and is especialiy suitable for use in packing singulated bare die for high-speed automated chip-on-board (COB) and fiip-chip (DCA) assembling. 2 Scope

46、This document contains dimensional specifcations and tolerances for Smm, 12- 16mm, 24- 32mm, and 44mm wide SURFTAPES which conform to applicable dimensional standards of EIA-48 1 and EMS- 747. SURFTAPE is covered by patent number 5,203,143; other patents are in process. 3 Description SURFTAPE is a v

47、ariation of conventional punched plastic carrier defined by EIA-48 1-1 and of adhesive backed punched plastic carrier defined by EMS-747. For ease of reference and clarity of presentation, the following descriptions highhght the specific features and variations of SURFTAPE compared to EIA Standard p

48、unched der tapes. Note the following specifics: 1) The punched plastic carrier tape frame is similar to that defued by EIA-48 1-1 and the same as the frame defned by EMS-747. 2) A pressure-sensitive adhesive (PSA) stratum replaces the conventional bottom cover tape shown by EIA-48 1-1. This PSA stra

49、tum comprises two parailel strips or rails of sticky tape, rather than a single with of PSA tape as shown by EMS-747. A gap of precisely controllable widh is maintained between the two dclq tape rails. Purpose of this gap is twofold: a) Provides clearance for a blunted, push-up pin to aid release of component fiom the PSA stratum. (Functionally equivalent to the hole in the bottom center of an embossed cavity.) b) Allows control of component adhesion to PSA stratum. Selection of specific gap width provides means for micrometer-like adjustment of amount of adhesio
