5.7.6.2 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.
5.7.6.3 Settings for Illuminating Standard Components
The standard range of components includes chips (0402 to 2220), tantalum capacitors, Melf components,
PLCCs, QFPs, SOs, SOJs, TSOPs, ICs, power components, flip-chips, µBGAs and BGAs.
For the components which are listed below the GF interpreter in the station computer uses the default illumi-
nation parameters listed in Fig. 5.7.7:
– Chips (0402 to 2220)
– Tantalum capacitors (component bodies, non-reflective)
– Melf
– PLCC, QFP, SO, SOJ, TSOP, ICs, power ICs
– Flip-chips, µBGAs, 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 5.7.6.4, Page 5 -
131).
