5.7.7.2 Pseudo color representation
The pseudo color representation provides a powerful and objective assessment of the illumination, by repre-
senting a brightness value in a color.
A contrast of at least 4 color scales between the lead and body is required for a measurement. In the ‘Illumina-
tion’ menu of the package form manipulator, components are displayed in the pseudo color representation on
the station computer monitor.
5.7.7.3 Setting values for the illumination of standard components
The range of standard components includes tantalum capacitors, PLCCs, QFPs, SOs, SOJs, TSOPs, ICs,
power components and BGAs.
For the components listed below, the package form interpreter in the station computer uses the preset illumi-
nation parameters listed in Fig. 5.7.9:
– tantalum capacitors (component body, not mirrored)
– PLCC, QFP, SO, SOJ, TSOP, ICs, power ICs
– BGAs (not for 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 5.7.7.4, Page 5 -
137).
