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.

(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).

(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, the feeding is performed twice, each

time with 12 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).
