Handling Control Board
Note the followings when handling PC boards.
z Do not touch control boards by wet hands.
z Do not handle and place the control boards onto any place where any metal chips are around or easily

Electrodes on Feeder / Feeder Bank
Tape feeder is able to run by receiving an electric signal from machine via feeder bank. When contact
failure occurs between feeder bank and machine, tape feeder may not run normally and steady, and it may
cause component pick-up error.
When electrodes on the feeder bank and the machine get dirty, clean them as follows:
NOTE: When the electrodes are touched by hand or have come into contact with foreign matter, cleaning is
recommended even if no dirt can be observed visually.
ACTION: Use a dry cotton swab or non-woven cloth and gently wipe off any dust on the electrodes. While cleaning
the electrodes, check and make sure that the pins on the electrodes are not bent. When it is found that the
pins are bent, contact us for repair. Continuing to use the tape feeder with its pins bent, pins may scratch the
contact surface of the feeder bank.
Do not use alcohol, water base detergents and organic solvent, such as
thinner, benzene and acetone.
Do not use sandpaper and tools with sharp blade or edge, such as a knife and
a screwdriver.
NOTE: When stubborn stains and dirt are on the electrodes, do not try getting rid of them forcedly. Please contact
us.
