This menu allows you to change
– the lead dimensions,
– the package dimensions,
– the ball imaging parameters,
– the illumination parameters and,
– the transformation table.
– Lead dimension parameters are
– optical lead length in the x and y directions of the component
– optically lead width in the x and y directions of the component
– pitch of the leads in the x and y directions of the component. Pitch means the distance from
the center of one lead to the center of the next.
– number of leads in the x and y directions of the component
NOTE
The pitch and number of leads can only be changed in the line computer.
– Package dimension parameters are
– the outside dimensions of the component in millimeters in the x and y directions. Outside
dimensions means the optical dimensions of the component including the lead dimensions.
The geometric dimensions of the leads and component are stored in the GF file in the line
computer. Depending on the geometry of the component and on its illumination by the com-
ponent camera, it is possible that imaging errors may occur. The image does not reproduce
the life-size geometric dimensions but reduces them. This is what is called imaging reduc-
tion. For this reason one refers to the optical dimensions of the leads and component. For
each lead dimension and package form the reduction factor is included in the GF file in the
line computer and can be modified with this menu. The reduction factor is entered in the
"Real-MA" file.
As regards defining the position of the origin of the coordinates system and defining regular and
irregular components, please refer to Section 6.3.2 on page 6 - 197.
– Ball imaging parameters are
– inner and outer radius type
– inner and outer radius
– contrast

– ball model
– Illumination parameters are
– the contrast in the image
– the X plane, flat, middle and steep illumination levels for illuminating the component
(brightness control).
– Color representation parameters (5 sections)
– 10 parameter IN values
– 10 parameter OUT values
The parameters are stored in the GF file in the line computer. Upon request the GF file will be sent
to the station computer. Finally it will be converted and transferred to the MVS computer.
If you modify a parameter, it will be entered in the x.SST file. The x.SST file will be converted and
loaded into the MVS computer.

Å You can use the arrow keys to increase or decrease the brightness of the rows of LEDs in the
component camera system which illuminate the component. The brightness can be set within
a range of 256 steps with 255 being the maximum value.
Å Use the spacebar to toggle the step size for changing the brightness from 1 to 10 µm and back.
Å Use the tab key to move between the four illumination levels: steep (top row of LEDs), medium
(second row of LEDs), flat (third row of LEDs) and X plane camera lighting (bottom row of
LEDs). The X plane illumination level is used to optically center flip-chip components on the 6-
nozzle revolver head with the illumination system for flip-chips, bare dies and standard com-
ponents.
Å Press the 5HWXUQ key to execute the individual measurement steps which are included in the
measurement conditions.
Å With (VFyou can quit the option. You will then be returned to the 7HVWFRPSRQHQW menu.
NOTE
Section 6.7.6 from page 6 - 304 contains instructions for selecting the illumination parameters.
