A-4 Is the top film take-up reel reverse torque as specified?

Reverse torque 1.0 kgf minimum

Forward torque 0.07 kgf maximum

Measure the above torques with a push-pull gauge, and replace the top film take-

up reel if they are not within specification.

Refer to section 2.2 “Film Take-up Reel Reverse Torque Check” of Chapter 2 of this

part for details on measurement.

A-5 Is the take-up lever tracking the feed lever?

If the take-up lever tracking is not operating normally, the take-up lever will

collide with the aluminum bracket or take-up reel. In this case, replace the take-up

reel.

This can be caused by deformation of the aluminum bracket, in which case the

bracket should be replaced (see B-3).

A-6 Try replacing the take-up spring

If you suspect the top film take-up (peeling force) is weak, replace the take-up

spring. The spring force should be selected from the table below. Springs are only

available for the W8 mm tape feeder.

B Excessive parts tape feed errors

B-1 Does the part’s tape feed pitch match the feeder specification?

Check whether the part’s tape feed pitch matches the feeder specification.

B-2 Is the rotation torque of the reel in the holder within specification?

(for W8 mm tape 13-inch parts reels)

Set the rotation torque measurement reel into the reel holder and measure the

rotation torque with a push-pull gauge.

For 200 mm/s, the maximum starting torque should be 0.5kgf.

Note : The rotation torque measurement reel is a dummy reel made with the following

maximum values :

Reel center width 14.0 mm x 100 mm diameter

Reel peripheral width 13.1 mm

Weight 740 g

B-3 Is there any problem with the tape feed lever height?

Is the aluminum bracket bent?

The feed lever height is as indicated below.

If the aluminum bracket is bent, it will degrade top film take-up torque or tape

feed lever operation.

If 8 mm feeders are set in place, it may also cause adjacent feeders to interfere with

other.
