(b) Taping quality requirements including maximum number of missing components.
卷装质量要求，包括产品遗漏的最大数量；
(c) Container and reel marking requirements (including bar code labeling if required), and reel diameter
(refer to 4.12 and Figure 10).集装箱和卷轴标识要求(如需要的话，包括条形码贴标签)和卷轴直径(参考4.12和图10)。
(d) Shipping conditions, storage conditions and storage time.运送条件，储存条件和储存时间。
(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. 包含元件的卷轴的重量。注意：重的卷轴可能无法在所有的载体供料机上工作。此外，一卷包含
元件的卷轴放在载体供料机上可能超出规章或公司规定的工人举起的重量限制。
4.3 Several conditions exist that may cause functional problems with carrier tapes and/or tape feeding
systems even though the dimensions are within the parameters specified in the tables and figures of this
document:
几种条件存在可能会引起覆盖带和/或载体的进料系统的功能性问题，即使尺寸是合乎本文献的表格和图形中指定的参数。
(a) Based on the carrier style, tape thickness T, tape cavity depth T2, outside pocket width B1, the cavity
pitch Pl, or the reel flange diameter A, the following conditions may cause problems with tape
feeding systems and should be considered as part of the procurement documents and quotation
requests as applicable: 根据载体的类型，带子的厚度T，载体格子深度T2，格子外侧宽度B1，格子间距P1，或者卷轴法
兰直径A，下列条件可能造成载体的进料系统问题。如适用，应视为采购文件和报价请求的一部分：

(b) For 8, 12, 16 and 24 mm wide embossed tapes, if S1<1.0 mm (Table 2 and Figure 6), there may not
be enough area to obtain a proper seal between the carrier and cover tapes according to paragraphs 4.5
and 4.11 and must be considered as part of the procurement documents and quotation requests as
applicable.
对于8，12，16和24毫米宽的压纹载体，如果S1<1.0毫米（表2和图6），根据4.5和4.11段，在载体和覆盖带
之间可能会没有足够的区域获得适当的封合，如适用，应视为采购文件和报价请求的一部分。
(c) 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 result 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 environmental 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
EIA-541. 用户可能遇到一些重量小的元件由于静电效应（吸引力和/或排斥力）以及覆盖带和载体在在进料的操作过程中
分离的问题。这一现象的结果可能会导致器件移动，或在放置的过程中远离用户的获取点，造成了误取或不取的情况。为了减
少这种现象，因此建议包装材料、元件贴装设备和控制环境条件加以优化，从而有效地消除任何电荷的形成。这种电荷，通常
被称为摩擦电荷，应根据EIA-541的指导方针予以控制。
