Color input parameter
This is to input, add or delete color information of band that is currently selected.
Band No
Select band No.
Band size (width/height)
Judge size of area for band color inspection.
Min distance
Min distance means relative distance to target color from each reference color. This is to
distinguish normal condition during inspection.
Position input parameter
Set position of currently selected band. Click <Set> button in position input window and
position in color band area in color band resistance window to enter parameter.
2) Teaching method
① Click <resistance color band inspection window> button among operating buttons.
② Select proper light for good expression of component color band and draw window on
component as shown in [Figure5-132].
③ Set direction of color inspection window. (reference direction will be from the first color to the
last color.)
④ Enter resistance value, tolerance and number of color band in color band parameter screen.
⑤ Enter color band inspection area, size of inspection area, and inspection color in color input
parameter screen.
⑥ Draw mounting inspection window for position compensation.

⑦ Group mounting window and resistance color band window into „Group component‟.
⑧ If there are components with same resistance on many parts of substrate, add it in the library,
too.
3) Inspection result in status window
For direct inspection of inspection window that completed teaching, select both of mounting
window and resistancecolor band window at the same time using selection button ( ) and select
„inspect‟ in popup menu displyed by clicking right button of the mouse to displaythe following
inspection result in status window in the main screen.

Inspection type
This is to display current inspection type.
Current color
Display color of resistance color band inspection window that is currently inspected by color
band order in RGB value.
Reference color
This means inspection reference color. In other words, display resistance color band color of
golden board by RGB value for each detected color band order.
Color distance
This means relative distance of reference color and current color. In case of occurrence of
false defect, adjust min distance in color input window or add reference color to adjust it.

5.3.12 IC offset inspection window
- IC offset inspection is algorithm to inspect status (lead offset, lead shift, lead tip offset) of
IC lead and mounting status (Shift, Tilt) of IC after mounting.
- Besides default light, sub light can be used for lead inspection and pad inspection, and
false defect that can occur under default light can be reduced.
1) Teaching method
① Click <IC offset inspection window> button among operating buttons, and draw window at IC
position of IC desired to be inspected. In general, draw window that is larger than pad area
desired to be inspected.
② Teaching tap teaching
- Select preview in operation window.
- Set light type and image type and binarization for good separation of lead.
- Adjust stripe width and area for noise removal.
- Set number of lead, lead tip, offset, and pad length.
③ Lead inspection tap setting
- Select default light tap, and select light type and inspection type (image type) for lead
inspection.
- Select auto or manual for binarization method. If „manual is set, set binarization value to
clearly display lead.
- Set stripe width and area for noise removal.
- Set search start position, search range, and contrast level for lead inspection. If „auto‟ is
set, check search range auto extraction.
④ Pad inspection teaching
- Select default light tap, and select light type and inspection type (image type) for pad
inspection.
- Select auto or manual for binarization method. If „manual is set, set binarization value to
clearly display pad.
- Set stripe width and area for noise removal.
- Set search start position, search range, and contrast level for pad inspection.
⑤ Check whether to use sub light or not. Select sub light tap that is activated in lead inspection
and pad inspection to set parameter. (light type and image type change)
⑥ Select monitoring option.
