Vision Type 180 (185) SOT-type parts
Use this vision type for parts with between 2 and 6 leads where the body color is black and
only the leads are visible during vision processing. Enter the body size and element
information in part data. Vision type 180 uses the body center while vision type 185 uses
the part center
Note: This vision type can be used for parts with up to six leads. Vision processing is not possible
for parts with 7 leads or more.
Note: Vision processing may not be performed if the lighting is unevenly reflected by leads.

Vision Type 181 Coil parts with two leads at 45 degree angles
Use this vision type for coil parts with 2 leads that are at 45 degree angles from the x-axis
(as shown below). The body color is black and only the leads are visible during vision
processing.
It is necessary to input the following body size and element information.
• The lead elements must be defined as “Side 0” and “Side 2”
• For each element, define the number of leads as [1].
Vision Type 230 (235) Black bodied BGAs
Vision Type 231 (236) White bodied BGAs
Vision Type 233 (238) Black bodied CSPs
Vision Type 234 (239) White bodied CSPs
Enter the part body size and element information in part data. Vision types 230, 231, 233,
and 234 use the body center while vision types 235, 236, 237, and 238 use the part center.
Due to the use of frontlighting, there are cases in which the image of the ball grid may vary
depending on the shape of the leads and the lighting conditions. In such cases, it may be
necessary to make adjustments to the ball grid position, length and width of the lead
information in element information.
Note: For details on parts that contain bumps in a non-symmetrical pattern, refer to vision type
142(147).

Vision Type 241 Insertion pin inspection
Vision Type 242 Insertion pin inspection
Vision Type 243 Insertion pin inspection
This vision type uses only the “sidelight” lighting pattern.
Vision type 241 determines positioning based on the shape of the part, and then checks for
bending of the pins. Vision type 242 estimates positioning based on the shape of the part,
and the makes a final determination of positioning based on the pins. Vision type 243
checks for bending of the pins, and then determines positioning based on the pins.
Body size and element information should be entered in shape data. It is also necessary to
enter radical data for vision type 241 and 242.
Vision Type 251 Segmented parts inspection
This vision type is different from vision type 252, and should be used for rectangular parts
whose body is divided into several different sections. Body size, body tolerance, and body
color should be entered in shape data.
Note: Refer to vision type 60 for rectangular chips.
Vision Type 252 Bodied parts inspection
This vision type is used for those parts with a white or gold colored body, and processes
only the part outline.
It is necessary to enter the body size in part data. The body size should be measured from
edge to edge. Positioning is performed using the outer-most points on the upper and lower,
and left and right part edges.
