6.7.7.2 Pseudo color representation
The pseudo color representation provides a powerful and objective assessment of the illumina-
tion, by representing a brightness value in a color. 6
A contrast of at least 4 color scales between the lead and body is required for a measurement. In
the ‘Illumination’ menu of the package form manipulator, components are displayed in the pseudo
color representation on the station computer monitor. 6
6.7.7.3 Settings for Illuminating Standard Components
The standard range of components includes tantalum capacitors, PLCCs, QFPs, SOs, SOJs,
TSOPs, ICs, power components and BGAs. 6
For the components which are listed below the GF interpreter in the station computer uses the
default illumination parameters listed in Fig. 6.7 - 9
: 6
– Tantalum capacitors (component bodies, non-reflective)
– PLCC, QFP, SO, SOJ, TSOP, ICs, power ICs
– BGAs (not ceramic BGAs)
As a rule you will not need to change the illumination parameters for the standard components.
For all other components you will need to determine the illumination values and test them (see
Section 6.7.7.4
on page 364). 6

Measure outline.
2. Trick: Use flat and middle levels to
bring leads image to saturation.
