(From Standards Proposal Number 5237, formulated under the cognizance of the EIA Automated Component Handling Committee (ACH).) 1 Scope This Standard covers requirements for taping micro-sized surface mount components onto embossed carrier tape 4 mm wide and with 1 mm po
13、cket pitch. 2 Introduction This Standard was formulated to provide dimensions and tolerances necessary to tape micro-sized surface mount components such that they may be automatically handled. 3 Applicable Documents Unless otherwise specified the following documents form a part of this standard to t
14、he extent specified herein: EIA-383 “Preparation for the Delivery of Electrical and Electronic Components” EIA-481 “8 mm Through 200 mm Embossed Carrier Taping and 8 mm & 12 mm Punched Carrier Taping of Surface Mount Components for Automatic Handling” ANSI/ESD S541 “Packaging Material Standards for
15、ESD Sensitive Items” EIA-556 “Electronic Industries Association Outer Shipping Container Bar Code Label Standard” EIA-583 “Packaging Material Standards for Moisture Sensitive Items” EIA-624 “Product Package Bar Code Label Standard for Non-Retail Applications” JEP95 “JEDEC Registered and Standard Out
16、lines for Solid State and Related Products” IPC 7351 “Generic Requirements for Surface Mount Design and Land Pattern Standard” 4 Requirements 4.1 Carrier tapes, cover tapes, reels, and taped components must meet the requirements defined in the Figures and Tables presented herein. 4.2 Procurement doc
17、uments and quotation requests shall include the following information: EIA-971 Page 2 (a) Reference to this Standard by Title and Number. (b) Taping quality requirements including maximum number of missing components. (c) Container and reel marking requirements (including bar code labeling if requir
18、ed), and reel diameter (refer to 4.12 and Figure 4). (d) Shipping conditions, storage conditions and storage time. (e) Weight of the reel containing components. 4.3 Several conditions exist that may cause functional problems with carrier tapes and/or tape feeding systems even though the dimensions a
19、re within the parameters specified in the tables and figures of this document: a) Users may experience problems feeding low mass components due to electrostatic effects (attraction and/or repulsion) associated with the separation of the cover tape and carrier tape during the feeding operation. The r
20、esult of this phenomenon could cause devices to migrate, or be propelled away from the user pick up point, resulting in a mis-pick or non-pick situation during placement. To minimize this phenomenon, it is recommended that the packaging materials, component placement equipment, and controlled enviro
21、nmental conditions be optimized to effectively dissipate any charge buildup. This charge, commonly referred to as tribo-electric charge, should be controlled per the guidelines in ANSI/ESD S541. b) Carrier tapes may experience feeding problems when passed through tracks with lengths in excess of 250
22、 mm. c) Camber in excess of 1 mm over 250 mm may be generated when empty carrier tape is supplied on level-wound reels. d) For micro-sized components (0603 Metric/0201 Imperial and smaller), the mass is so light that components may run off from the component compartment when the cover tape is peeled
23、. For these component sizes it is recommended to use a peel force of 0.2 N (20 grams force) 0.1 N (10 grams force) and, as aging may affect the peel force, this peel force should be valid for at least 7 days after sealing. 4.4 Components are to be prevented from falling out of the cavity of the carr
24、ier tape, and shall remain in position for automatic handling after removal of the top cover tape (see Note 1, Table 1). 4.5 The cover tape(s) may not extend over the edge of the carrier tape or cover any part of the sprocket holes. 4.6 Tape in adjacent layers shall not stick together when wound on
25、the carrier reel. EIA-971 Page 3 4.7 The packaging, materials and processes shall not adversely affect the mechanical and electrical characteristics or marking of the components. For intermediate and final packaging, refer to EIA-383 “Preparation for the Delivery of Electrical and Electronic Compone
26、nts,” ANSI/ESD S541 “Packaging Material Standards for ESD Sensitive Items,” and EIA-583 “Packaging Material Standards for Moisture Sensitive Items,” and EIA-624 “Product Package Bar Code Label Standard for Non-Retail Applications.“ 4.8 The tapes shall be suitable to withstand storage of the taped co
27、mponents without danger of migration of contaminants onto the terminations, or the emission of vapors which would make soldering difficult or deteriorate the component properties or terminations by chemical action. In addition, the cover tape shall not become detached, such that the components do no
28、t remain in position after storage. 4.9 Components may be removed from the cavity by incising at or below the cavity depth midpoint (K0/2). In no case shall the incising affect the package functionality. 4.10 There shall not be consecutive components missing from any reel for any reason. 4.11 The co
29、ver tape shall have a total peel strength of from 0.1 N to 0.7 N (10 grams to 70 grams calibrated scale reading). Peel is defined as the separation of the full width of the cover tape from the carrier tape or the removal of the center portion of the cover tape from the carrier tape to enable compone
30、nt removal from the cavity. The direction of pull shall be opposite the direction of carrier tape travel such that the cover tape makes an angle of between 165 and 180 degrees with the top of the carrier tape. The cover tape, during peel force testing, shall be pulled with a velocity of 300 mm +/- 1
31、0 mm/minute, relative to the carrier tape, during peeling, which results in the cover/carrier tape seal being separated at a rate of 150 mm/minute. 4.12 Bar code labeling (if required) shall be on the side of the reel opposite the round sprocket holes (refer to 4.2(c) and Figure 4). Refer to EIA-556
32、 and EIA-624. 4.13 Reels as defined by Figure 8 shall be permanently marked with visible recycling symbology. 4.14 The following component orientation rules apply: a) The longer axis of the component shall be oriented perpendicular to the length of the tape (B0 A0). b) Polarized components shall be
33、oriented in one direction. For components with two terminations, the cathode side shall be adjacent to the sprocket holes. EIA-971 Page 4 Figure 1. 4 mm Carrier Tape Dimensions.
