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 three illumination levels: steep and medium and flat cam-
era lighting.
Å Press the Return key to execute the individual measurement steps which are included in the
measurement conditions.
Å With Esc you can quit the option. You will then be returned to the Test component menu.

6.6.4.9 Package Dimension Option
There is potential for the occurrence of an effect called image reduction mainly with cylindrical
components, with PLCCs, BGAs and µBGAs. The reduction is caused by the round features of
the components that deflect incident light away from the camera sensor. Typically, the round
edges then become invisible to the camera. To remedy this problem, use the Package Dimension
option to change the optical package width and length to accommodate for the loss. 6
