the service position once more after the reference sequence. The station computer program

will continue to prompt for a nozzle change until you have obtained the correct configuration.

If you do not succeed, then proceed as follows:

Æ Switch off the station and cancel the specified job on the line computer.

Æ Rectify the nozzle error and restart the station.

TIP

Have the nozzles ready in a separate nozzle box in which each compartment is labeled with the

type and color of the nozzle. This will help to prevent confusion. Do not save used plastic nozzles,

dispose of them immediately instead. 3

3.4 When you change shift

Æ Splice the tapes early enough so that the feeder modules do not have to be refilled as soon as

the new shift starts. This will prevent lead to pick-up errors and prolonged down times.

Æ Inform the next operator of any important information when changing shifts when, for example,

something has been changed in the placement program or if errors have occurred more fre-

quently in certain feeder modules. Also read through the list of the descriptions of the steps to

take in section 3.6

Æ Carry out a set-up check.

Make sure that the feeder modules are equipped with the correct components and that they

are at the correct locations in the component table.

NOTE

Hand over the line in the same state that you would want to find it in when starting your shift.

This means that:

- The rejection containers are empty.

- The waste containers are empty.

- The conveyor areas have been cleaned with a vacuum cleaner.

- Defective feeder modules in the feeder area have been replaced.

3.5 When you, as an operator, carry out a walk-through

inspection

Æ Make sure that the tape is correctly placed in the springs of the 8 mm S feeder.

Æ Check whether the tape foil removal container for the 8 mm 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 to problems with the tape removal mechanism.3

Æ Check to ensure that the withdrawal space on the feeder module is the right size for the com-

ponent.

Æ Check to see if tape guides are being used on the feeder modules that are intended for different

tape widths.

Æ Check to see if the additional plastic guides are being used on the feeder modules that are in-

tended for tapes of different widths.

Æ Check the position of the stopper on the PCB transport.

Always position the stopper so that it is not placed within any cut-outs or recesses in the PCB.

Æ Check the magnetic supports on the lifting table. They must be arranged so that they do not

collide with components on the bottom of the PCBs.

NOTE

Splice the tapes early enough so that the feeder modules do not become empty or you will

experience 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 pro-

longed down times. 3

Æ Place insertable shafts into the tape container when using large tape reels.

Æ Insert the dividing plates as shown in Fig. 3.5 - 2 and remember that the smallest division of the

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