[4] Lead inspection
· Inspection procedure
1Calculate the mid points (K1 to K4) of the leads along the inspection line.
2 Look for bent leads by comparing the difference between the maximum and
minimum distances of P1 to P3 .
3Check the maximum and minimum length of the leads (L1 to L4).

Based on positional information obtained from the gray scale search function, inspect the
condition of IC leads and connector pins. (No. of detected lead pins: Max. 128 pieces)

Detect the existence/absence and size of a workpiece when “the workpiece is one point” or
“measurement position is fixed.”
· Convert the specified pixel area to binary values and measure the size of the white area.
Check for the existence of bearings inserted by a bearing insert machine, prevent contam-
ination of different parts in automobile production lines, determine the type of water-proof
caps, check for the existence/absence of bottle labels, inspect the cuircuit traces on
PWBs, check for the presence of grease, check for existence of frozen foods.
