定义,它包围着元件并留有充分的间隙:
(a) the component does not protrude above the top surface of the carrier tape.
元件不超出载体的顶面。
(b) the component can be removed form the cavity in a vertical direction without mechanical restriction,
after the top cover tape has been removed.
在去除顶部的覆盖带后,元件可以在垂直的方向上无任何机械障碍地从格子中取出。
(c) rotation of the component is limited to 20°maximum for 8 and 12 mm tapes and 10°maximum for 16
mm and 24 mm tapes (see Figure 8).
8 12 毫米的载体,元件的转动范围限制在 20°以内;16 24 毫米的载体限制在 10°以内(见图 8)
(d) lateral movement of the component is restricted to 0.5 mm maximum for 8 mm and 12 mm wide tape
and to 1.0 mm maximum for 16 mm, 24 mm wide tape (see Figure 9).
8 12 毫米的载体,元件水平方向上的移动量限制在 0.5 毫米以内;16 24 毫米的载体限制在 1.0 毫米以内(见图 9)
(e) see Addendum for standards relating to more precise taping requirements.
参照附录查找相关更多精确的卷装要求的标准。
2. The tape with or without components shall pass around R without damage (see Figure 11).
有无元件的载体应可无损地通过圆形 R(见图 11)
3. If S1<1.0mm, there may not be enough area for cover tape to be properly applied (see paragraph 4.3(b)).
如果S1<1.0毫米,可能会没有足够的区域使覆盖带获得适当的封合(见段落4.3(b)
