15.Routine Inspections and Maintenance
This chapter describes parts of the machine that must be cleaned relatively
frequently. If cleaning is neglected, machine operation will be impaired and
placing performance will drop.
15.1Cleaning the Nozzles
The vacuum nozzles draw in air. Nozzle blockage occurs when particles
of dust, glue, and solder paste are drawn in and solidify.
If this blockage is not corrected, pick-up errors will occur and placing
performance will drop. If a certain nozzle consistently causes pickup
errors, clean it out by inserting and turning a drill bit as shown in the
illustration below.

15.2Cleaning the Fluorescent Disk (Once a Month)
If dust or other fine particles build up on the fluorescent disk, the
percentage of UV light reflection from the station 4 UV lamp will be
reduced. If this reflected light is insufficient, a proper image can not be
captured during vision processing. Vision processing errors thus occur
and placing performance drops. If a certain nozzle consistently causes
pickup errors, clean its fluorescent disk with a soft brush (the type of
brush used for cleaning a camera lens is best). Do not rub the fluorescent
disk with a rag. Rubbing the fluorescent disk makes grime cohere to the
sheet, which causes vision processing problems.
If grime cannot be removed, replace the fluorescent disk.
15.3Cleaning the Shaft (Once a Month)
Shaft movement slows if grime and lubricant collects on it. If the shaft
does not move fast enough, vertical movement during the placing
operation is adversely affected and placing performance drops. Clean the
shaft and holder with a dry cloth. Refer to figure 15-2 below.
Note: Do not use kerosene, thinner or alcohol based solvents as these will damage
the holder.

15.4Cleaning Out the Waste Tape Box (Every 8 Hours)
Tape cut by the waste tape cutter travels through a tube to the waste tape
box. Empty the waste tape box every eight hours, as a large amount of
waste tape collects after eight hours of production. When cleaning out the
waste tape box, check the filter above it, and, if necessary, clean the filter
with a vacuum cleaner.
