11.7 Flow Chart for Identifying the Cause of Pick-up Error
This ow chart is to identify the cause when any component pick-up error occurs.
11.7.1 A Vertical Component Occurs
A vertical component
occurs frequently.
Recall Check
Does it occur on the same nozzle?
Is the line sensor measured value the same?
Pick-up height setting check
The pick-up height setting in the library is
proper?
Are the settings of simplified packing type and
feeder offset B correct?
Pick-up position check
Is the pick-up position not deviated?
Component Check
Is the clearance for the component pocket too
large?
Clean the nozzle.
Clean the line sensor.
Teach the pick-up position.
Adjust the pick-up position
(using the feeder adjusting jig).
Standard Pick-up Height Setting
8 mm Width Paper Taping
0603 Size : -0.1 mm
1005 Size : -0.05 mm
1608 Size : 0 mm
8 mm Width Embossed Taping
0 mm (regardless of the size)
Turn off the pick-up position adjusting
function.
