(f) Use a taping on condition that the component itself or its electrical contact
is not protruded from the upper surface of tape.
Embossed Taping
"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. 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.

9.3 Leader Section (Tape End Section)
9.3 Leader Section (Tape End Section)
The tape length in the leader section should be 400 mm or more including
the empty component compartment.
Such empty component compartment should be sealed with a cover tape for
100 mm or more.

9.4 Trailer Section (Tape Tailer Section)
The tape length of the trailer section should be 160 mm or more including
the empty component compartment.
The empty component compartment should be sealed with a cover tape.
The last portion of carrier tape shall release from the reel hub.
9.5 Position of Taped Component
0410-002 100
Keep a clearance around the component such that the direction of the
component is not changed in the punched section or within the em-
bossed section and so that it can easily be picked up from the punched
section or within the embossed section.
