(2) Machine-Based Factors

When a component has no problem, check the main body of the ma-

chine.

A failure can be tracked by checking if it occurs on a specific vacuum

nozzle or feeder slot No.

(2-1) When a failure occurs on a specific vacuum nozzle, check the

following items concerning the pertinent vacuum nozzle.

• Check if the nozzle is abnormal.

• Check if the vacuum line is abnormal.

• Check if the vacuum ON/OFF valve is abnormal.

When a factory is dusty or a lot of components packaged in paper

tapes are used, the vacuum nozzles and their filters get dirty easily.

Therefore, it becomes important to clean the vacuum nozzles and fil-

ters periodically.

Refer to "(1) Frequent Failures on Specific Vacuum Nozzle" in "5.2.2"

for the troubleshooting.

(2-2) When a failure occurs on a specific feeder slot No. (feeder No.),

check the following items concerning the pertinent feeder slot

No. (tape feeder).

(1) Check if the tape feeder is loaded correctly with components.

(2) Check if the top cover tape is peeled off normally.

(3) Check if the data related to the component picks is normal.

Refer to "(2) Frequent Pick-Up Errors on Specific Feeder Slot No." in

"5.2.2" for the troubleshooting.

(a) See Figs. 4B33 and 4B34 on the next page for the check-

points on tape feeders.

(b) When a tape feeder loaded with different components is

installed, the pick-up position must be checked and the

offset data "Feeder-B" must be cleared or modified for the

new components after program change operation because

it is prepared for the previous components.
