5. Maintenance Method

Periodically clean the vacuum nozzles to maintain reliable and stable component

picks and placement.

•

It is advisable that the nozzles be cleaned at least once a week.

Note

The nozzle for 0402 recommends the cleaning every 3 or 4 days.

•

Change cleaning frequency according to various frequency of use and

accumulation of debris along with certain environmental conditions.

•

When the vacuum suction force weakens or a nozzle constantly fails to pick or

place components, it is required to check the nozzle for debris and cleanliness.

Do not grasp this part strongly during the

nozzle cleaning.

Otherwise, the nozzle may be damaged.

When it is necessary to hold the nozzle firmly

try to grasp the collar portion.

When a recognition error occurs frequently,

rub the back of the collar approximately

20 times with a toothbrush.
