4、utlines for Solid State and Related Products” 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 The package design may utilize a carrier tape and cover tape which mechanically interlock across
5、 the carrier tape width at predetermined locations between each component row to secure, orient and accurately position components on the carrier tape. For flat carrier tape, this design may also include an antistatic foam interleave tape. 4.3 Procurement documents and quotation requests shall inclu
6、de the following information: (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 required), and reel diameter (refer to 4.12 and Figure 4). (d)
7、 Shipping conditions, storage conditions and storage time. (e) Weight of the reel containing components. NOTE: A heavy reel may not work on all feeders. Also, a reel containing components attached to a feeder may exceed regulatory or corporate weight limits for lifting by workers. 4.4 Components are
8、 to be prevented from falling out of the cavity of the carrier tape, and shall remain in position for automatic handling after removal of the cover tape (see Note 1, Table 1). 4.5 The packaging method shall not obstruct any part of the sprocket holes. 4.6 The carrier tape and/or the packaging method
9、 in adjacent layers shall not stick together when unwinding from the carrier reel. 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
10、 the Delivery of Electrical and Electronic Components,” EIA-541 “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 packaging method
11、 shall be suitable to withstand storage of the packaged components 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 packaging
12、method shall not become detached, such that the components do not remain in position after storage (see Subclause 4.3(d). 4.9 Components may be removed from the packaging (virtual) boundary by incising the cavity at or below the depth midpoint (K0/2) for embossed tape (Figure 1) or by incising the c
13、arrier tape along the packaging (virtual) boundary for flat tapes (Figure 2). In no case shall the removal affect the package functionality. EIA-704-A Page 3 4.10 There shall not be two (2) or more consecutive components missing from any single packaging boundary with multiple components or consecut
14、ive packaging boundaries with single components. 4.11 Components with bottom-only terminations shall be packaged with the terminations facing away from the component access side (see Figures 1 & 2). Refer to EIA-481-C for component orientation rules. 4.12 The cover tape may be separated from the car
15、rier tape by an unstitching device in the feeder. The force required to remove the cover tape shall be 22.1 N to 88.3 N, depending upon the carrier tape width. The direction of the force shall be at an angle of 90 degrees to 180 degrees with the top surface of the carrier tape. The unstitching devic
16、e may travel though the punched holes in the mechanical interlock area (see Figures 1 & 2), perpendicular to the top surface of the carrier tape, and shall not deform the carrier tape. The act of separating the cover tape from the carrier tape shall not affect the component or its position on the ca
17、rrier tape. 4.13 Reels as defined by Figure 3 shall be permanently marked with visible recycling symbology. Bar code labeling, if required, shall be on the side of the reel opposite the round sprocket holes (refer to 4.3(c) and Figure 4). Refer to EIA-556 and EIA-624. Left Intentionally BlankEIA-704

(b) No part or feature of th
22、e component(s) may extend beyond the virtual boundary. (c) The tape surface with the virtual boundary may contain any number of surface features. These surface features may include prepunched holes, pressed tabs, embossments, pocket cavities or other mechanical features to secure the component. Thes
23、e surface features will in no way restrict the functions of the feeder. (d) The component(s) located within the virtual boundary can be removed from the carrier tape in a vertical direction without interference from any other components. Extraction force required to remove components from the carrie
24、r tape shall not exceed 3.3 N maximum calibrated gauge reading. (e) Kn defines the maximum distance from the top surface of the carrier tape to the lowest feature below the carrier tape surface. (f) K1defines the maximum distance from the top surface of the carrier tape to the highest feature. 2 Tap
