The sensor-specific part contains
– the measurement conditions for the component,
– the type of lighting and
– the transformation table data.
NOTE
The buttons of the options of the Test component menu will only be active if you have already loaded a pack-
age form.
Fig. 5.6.19 Test component menu, options
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. By pitch is meant 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. By outside dimen-
sions is meant 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 component camera it is possi-
ble that imaging errors may occur. The image does not reproduce the life-size geometric dimensions but
reduces them. This is what is called imaging reduction. 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 5.3.5.
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.

Illumination
Option
When this option is selected the video image for checking and setting illumination will appear.
Fig. 5.6.20 Test component menu, Illumination video image
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.
Use the spacebar to toggle the step size for changing the brightness from 1 to 10 µm and back.
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 illu-
mination level is used to optically center flip-chip components on the 6-nozzle revolver head with the illumi-
nation system for flip-chips, bare dies and standard components.
Press the Return key to execute the individual measurement steps which are included in the measure-
ment conditions.
With Esc you can quit the option. You will then be returned to the Test component menu.
NOTE
Section 5.7.6 ’Setting the Components Illumination at the 12x Revolver Head Camera’, Page 128, and Sec-
tion 5.7.7 ’Setting the Components Illumination at the IC Head Camera’, Page 135, contain instructions for
selecting the illumination parameters.
