3.3.3. Inspection of Part Supply Accuracy of Feeder (Inspection)
After installing the tape feeder on the calibration jig, inspect the part supply accuracy of
the feeder referring to the following procedure (based on the SME 8mm feeder):
1. Insert the master tape into the feeder while lifting up the tape guide of the feeder and
have the sprocket engaged in the transfer hole of the master tape.
2. Move the tape guide down and secure the locker.
Caution
When moving down the tape guide, exercise care not to
have the transfer hole of the master tape dislocated from, or
stabbed by, the sprocket.

3. In order to check the part supply accuracy of the feeder, the origin of the feeder must
be found first. Since the master tape has no vinyl cover, insert the empty carrier tape
with no parts into the drain gear section of the feeder and have the empty carrier tape
detected by the vinyl detection sensor.
4. Feed the master tape so that the bent section at the end of the master tape will be
placed on the drain gear.
Memo
When performing a mapping inspection, set the master tape position
in the same manner.
Caution
We are not responsible for defective mapping and part
supply accuracy defects of the feeder due to overuse
(exceeding 150 times of use) of the master tape.
After using the master tape more than 150 times, replace it
without fail.
If the master tape is damaged or deformed, dispose of it
immediately.

Caution
We are not responsible for master tape deformation and
supply accuracy defects of the feeder which occur due to
the use of a master tape to which teflon tape is not attached
when using an SME feeder.
In the case of the master tape for an SME feeder, a teflon
tape is attached at the front. A master tape to which a teflon
tape is not attached is for an EXCEN feeder. Using such
tape for an SME feeder may cause master tape deformation
and part supply accuracy defect of the feeder.
5. Run the calibration jig program and adjust the threshold value of the master tape in the
following order:
