Embossed Carrier Type Taping
(a) A0 × B0 stands for the rectangle hole size on the tape.
The clearance between a rectangle hole and a component affects the pick-
up rate. Use the taping component with appropriate clearance specifica-
tions.
(b) The above specifications do not imply any guarantee of pick-up rate, etc.
The pick-up rate varies depending on how the main machine is adjusted
and the combination of the main machine and the tape feeders.
(c) Make a hole (D1) in the cavity if necessary.
(d) 10 pitches cumulative tolerance P0 should be ± 0.2 mm.
(e) The cover tape should run smoothly along the sprocket holes. The edges
of the cover tape should be aligned with the carrier tape (taping).
The thickness of the cover tape should be 0.07 mm or less (including
adhesion).

is not protruded from the upper surface of tape.

"Embossed depth (T3) > Component thickness"
(g) Shown in column "t" is the gap between the component pick-up and chute
surfaces.
As the gap can be adjusted by the stroke control, set the pick-up level data
in the component library data.
If dimension "t" is big, components may not stay still or may be tilted. Be
sure to adjust the dimension for the appropriate one in the range of values
specified in the table.
(h) The shape of component pick-up surface should be wide and smooth
enough to be picked up by vacuum nozzles.
(i) Cover tapes sometimes become thicker than expected due to leafy and
fluffy leftovers produced through the production process. However, the
overall thickness should not exceed the value described as "T2" in the
table.
(j) In the case of feed pitch of 24 mm or 32 mm, the feeding is performed
twice, each time with 12 mm or 16 mm. Confirm the pick-up position
when the tape is set.
(The pick-up position and the initial set position are different from those
for single feeding operations).

9.1 Allowable Limit of Edge Waving
Allowable limit of edge waving of tape should be no more than 1 mm per
100 mm through a length of 250 mm as illustrated.
Fig. 112 Test Method for Edge Waving of Tape
Fig. 111 Allowable Limit of Edge Waving of Tape
9.2 Test Method for Edge Waving of Tape
The edge waving of tape shall be tested in such a manner that one end of
tape is fixed, the tape is pulled by a force of 1N (102 gf) applied to the other
end, a graduated transparent plastic plate which also serves as a weight is
placed on the tape, and then the waving is measured.
