Defective Feeder Clamp
If the feeder is not inserted into the feeder bas slot or the clamping is not performed
smoothly and if the chip mounter does not recognize the feeder even though the feeder is
clamped, the user needs to check and pay attention to the following items.

High Part Dump Rate
If the part dump rate of the feeder is higher than the average dump rate, check the feeder
status referring to the following table.

Status
Causes Items for Check or Caution
Distorted part feeding position. Check for any problem after changing the pickup
mode to the individual pickup mode.
The part pickup height of the nozzle is
incorrectly set up.
Measure and reflect the actual thickness and height
of the corresponding part.
Defective
pickup
Incorrect setup of feeding pitch. Check if the part interval matches with the set pitch.
Setup speed of the cylinder is too fast. Regulate the cylinder speed control valve.
Defective tape guide operation. Check if the tape guide moves smoothly.
Defective shutter operation. Check if the shutter operates properly during manual
feeding.
A part is touched during shutter
movement.
Check visually for part interference during manual
feeding.

3.3. Troubleshooting of Frequent Error
3.3.1. Defective component supply
Any defective in the component supply, such as the tombstone and flipping of the
component, separation from the tape, etc. is generally caused by irregularities in the
shutter area.
Occurrence of Wear and Distortion to Major Parts
The part pickup position may be changed due to wear and distortion of major parts.
Therefore, perform calibration of the feeder periodically using a calibration jig.
☞ Calibration Cycle: Perform calibration of the feeder per 1.5 million times of feeding
or per six months.
Deformation of Tape Guide and Shutter
When the tape guide and shutter are deformed with the tape being installed, failure of
pressing the part (chip) causes defective part feeding.
In addition, even when the part comes out being scratched while moving backward since
the shutter height is low, it causes the defective part feeding.
☞ Perform replacement in the sub-assembly state with the tape guide being assembled
with the shutter.

Bad lubrication around the shutter area
This condition occurs when the shutter and the tape guide is not fully lubricated (if the
frictional force is felt when the shutter is moved back and forth manually).
☞ Solve this problem by applying the lubricant between the shutter and the tape guide.
If the problem persists even after the application of the lubricant, change to
subassembly state where the shutter is assembled into the tape guide.
Cylinder Air Leakage
Check the feeder pneumatic pressure of the MMI or check for the sound of air leakage
occurring around the cylinder.
☞ Check for the problem and contact our designated C/S (STS) or local agent.
Spring Wear and Cutoff
Check if the spring cannot perform its function due to wear or it was cutoff.
☞ Check for the problem and contact our designated C/S (STS) or local agent.
