search range for others. For example, set X-side search range to be large search range

of Y-side search range to be small

 For compensation window, use general mounting window. Like bridge, group them into a

component to make compensation window.

 Draw small IC component

 In case of IC component of which all components get into one frame, draw bridge for

each lead, and set compensation window and group into a component at one edge.

 For search range of compensation window, set about 20 of value for both of width and

height.

 Draw large IC component

 Conduct individual teaching for large IC component by moving frame.

 Lead tip display

 If lead tip auto search option is set for initial teaching, position of solder inspection width

will be drawn based on lead tip search start position. However, position of solder

inspection width will be displayed based on lead tip position found from manual inspection

more than 1 time.

 Set whether IC/Bridge inspection window conducts solder amount inspection for fillet part

or not. „Lead tip‟ tap and „solder amount inspection‟ tap will be activated when this option

is set.

 Direction

 Direction of lead spread based on IC component body.

[Figure 5-126 IC component shape]

 IC color

 Check at this function for lifted lead inspection by interlocking color inspection window

with IC Bridge inspection window.

 For normal range for IC color inspection, set it using pixel ratio (upper limit) and IC

average ratio inspection+ (%) (lowest limit) in color inspection window.

9) Common parameter

 For smooth conduction of the relevant inspection or area setting, there are items to

adjust parameter on each tap. The followings are parameters commonly used on each

tap.

 Binarization boundary value

 Auto: program automatically set binarization value for image binarization.

 Manual: users directly set binarization value for image binarization.

 Noise removal – stripe width (Pass Stripe)

 This is used to remove length direction noise component of lead from binarized image.

The larger value, the thinner lead width.
