Vision Type 142 (147) Black bodied parts with irregular bump patterns
Select this vision type for bump leaded parts with irregular bump patterns. Enter the body
size and element information in part data. Vision type 142 uses the body center while vision
type 147 uses the part center.
The following conditions apply to bump leads:
• There must be two or more bumps on the part.
• The pitch must be equal or greater to two times the bump diameter. However,
for parts with only two bumps, the pitch must be greater or equal to one sixth (1/
6) of the average body size in all directions.
Vision Type 143 (148) Ceramic column grid array (CCGA) parts
Enter the body size and element information in part data. Vision type 143 uses the body
center while vision type 148 uses 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.
Vision Type 144 (149) Land grid array (LGA) parts
Enter the body size and element information in part data. Vision type 144 uses the body
center while vision type 149 uses the part center.
Vision Type 151 (156) Black connectors placed using a mechanical chuck
Enter the body size and element information in part data. It is necessary to create separate
element information for leads of different width and length. Vision type 151 uses the body
center while vision type 156 uses the part center.

Vision Type 152 (157) Black bodied connectors
Enter the body size and element information in part data. It is necessary to create separate
element information for leads of different width and length. Vision type 152 uses the body
center while vision type 157 uses the part center.
<Examples of parts that can be inspected>
Lead
Black portion of the part (e.g. body or coating)
<Examples of parts that cannot be inspected>
The parts cannot be correctly inspected if any metal that
reflects light similarly to leads exists within the body
of the part.

Vision Type 153 (158) White bodied connectors
Enter the body size and element information in part data. It is necessary to create separate
element information for leads of different width and length. Vision type 153 uses the body
center while vision type 158 uses the part center.
Vision Type 160 (165) White connector body detection
Enter the body size and element information for leads or projections. Vision type 160 uses
the body center while vision type 165 uses the part center. Element inspection is not
performed if the [Result] option for that element is set to "Don’t inspect".
The body inspection points are automatically determined based on the data for leads and
projections specified in the element information. When detection positions cannot be
properly determined automatically, up to two elements per side can be specified in the
element information for the body inspection points. To specify body detection points,
specify the side and then enter the coordinates for the points to be inspected in [X] and [Y]
items for the position group and enter "0" for all other items for each “detection” element in
the element information.
Note: It is necessary to define leads in element information regardless of whether lead inspection
is to be performed for those leads or not.
Note: When the body detection option is specified, data should be specified such that there is a
minimum of one side where two points can be detected and a minimum of two sides where
one point can be detected. If there are an insufficient number of detection points, an error
occurs when data is registered.
Note: If the edges of the body of a part are not clearly projected, this may result in an error or a
drop in the placing accuracy.
Note: Correct processing cannot be performed if the nozzle protrudes over the edge of the part.
Note: If the straight line obtained from the specified detection points for the same line is not
parallel nor perpendicular to the straight line obtained from the detection points of another
side, then processing cannot be performed.

The outer form of the part is used to determine the rough
positioning of the part. Therefore inspection of the part
is not possible if the outer form of the part cannot be determined.
