6.5.3 QFP-100 and BGA-228 Slugs
The panel is populated with glass slugs for the corresponding component type. Fine pitch placement programs for
the QFP-100, and BGA-228 have the position and angular rotation pattern shown in Figure 6-10. Appendix E
presents the positions of the components with respect of the fiducials in numeric format.
Figure 6-10 Component Location Layout for QFP-100 and BGA 228 Slug Components
6.5.4 QFP-208 Slug
Figure 6-11 presents the placement layout for the QFP-208 slug component on the PVP. Appendix E presents the
positions of the components with respect of the fiducials in numeric format.
