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 specications.
(b) The above specications 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 (D

) in the cavity if necessary.
(d) 10 pitches cumulative tolerance P

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

(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 specied 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
uffy leftovers produced through the production process.
However, the overall thickness should not exceed the value described as
"T2" in the table.

9.1 Allowable Limit of Edge Waving of Tape
Allowable limit of edge waving of tape should be or less than 1 mm per 100 mm
through a length of 250 mm as illustrated.

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 xed, 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.
