There are several algorithms available in the Mark Type recognition mode.
(1) Special 6: Check direction (*This needs to be custom-ordered)
The method for positioning is the same as that of Mark 1. (There is only one object.)
The direction is determined by the brightness of the specified circular region.
Option 1: Recognition flag, the method to detect the inclination

IM-SMT-VSNDIC-0002-000
Option 2: Min. Brightness Difference (If the value is 0, 50 is set)
If the difference of the average brightness of the detected circle is less than the
value specified here, it is determined to be an error.
Option 4: “Cut Inner /Outer Noise”, the priority to perform “Cut Inner /Outer Noise”
function and the object type are specified.
The detection conditions for direction check are set to 1N Lead Group.
- Lead Group 1N: 1
*The detecting conditions for direction check are set to 1N Lead Group
- Lead Number 1N: 0
- Reflect LL 1N: 0
- Lead width 1N: Diameter of detection circle (mm)
- Lead pitch 1N: 0
- Find Pos. X 1N: Detection circle center position X
- Find Pos. Y 1N : Detection circle center position Y
Based on the results obtained from the “Direction check”, add +90°, +180° or +270° to
the tilt of the component and set the values.
(2) Special 8: 2 Objects (Angle of Terminal)
Perform the same recognition method as that of Mark 2.
The average center-of-gravity of the two objects is determined to be the center of the
component, and the inclination is determined as the inclination of the straight lines which
configure the objects.
When the straight lines configure the shape of the lead, the angle may be obtained more
correctly compare to the recognition by Mark 2.
Bit position
Check Type: (0: Black, 1: White)
Check Direction: (0: (0°, 180°), 1: (0°, 90°, 180°, 270°)
Least-square method is always used when performing inclination detection.
(For all the sides)
Performs inclination detection with reference to the side in N direction.
(when the inclination is not obtained correctly.)
Performs inclination detection with reference to the side in S direction.
(when the inclination is n
ot obtained correctly.)
Performs inclination detection with reference to the side in W direction.
(when the inclination is not obtained correctly.)
Performs inclination detection with reference to the side in E direction.
(when the inclination is not obt
ained correctly.)
