5.4 Carrying out a walk-through inspection

5.4.1 Checking the feeders

Æ Make sure that the tape is correctly placed in the springs of the S feeder.

Fig. 5.4 - 1 Placing the tape in the springs of the S feeder

Æ Check to see whether the tape foil removal container for the S feeder is full.

If it is full, then pull out the foil and cut it off with scissors.

NOTE

Tearing the foil instead of cutting it can lead problems with the tape removal mechanism.

For this reason the 3 x 8 mm feeders are fitted with an integral cutter. This is in the tape foil

removal container at the end of the feeder under the flaps. 5

Æ Check to ensure that the pick-up window on the feeder is the right size for the component.

Æ Check to see whether tape guides are inserted on combination feeders (24 mm / 32 mm).

Æ Check to see whether the additional plastic guide is inserted on combination feeders.

5.4.2 Checking the PCB supports

Æ Check the magnetic PCB supports on the lifting table. They must be arranged so that they do

not collide with components on the bottom of the PCBs.

5.4.3 Splicing the tape in good time

PLEASE NOTE: 5

Splice the tapes early enough so that the feeders do not become empty. Otherwise you will expe-

rience prolonged down times.

However, do not splice the tapes too early because if you wind the end of the old tape onto the

new reel after splicing, the reel holding the new tape may become overfilled and the tape will slip

off the reel and become tangled up. This will again result in pick-up errors and prolonged down

times.

5.4.4 Inserting dividing plates in the component trolley tape container

Æ Insert the dividing plates as shown in Fig. 5.4 - 2 and remember that the smallest division of

the tape container is a 2x division. This will help avoid placement errors.

Æ Check that the dividing plates engage in the same positions on both guide rails. Otherwise the

dividing plate will be offset or bent.
