5.1 S.E.C.C. Mechnical Specifications
S.E.C.C. package drawings and dimension details are provided in Figure 18 through Figure 27.
Figure 18 shows all views of the Pentium II processor in an S.E.C.C. package; Figure 19 through
Figure 22 show the S.E.C.C. package dimensions; Figure 23 and Figure 24 show the extended
thermal plate dimensions; and Figure 25 and Figure 26 provide details of the processor substrate
edge finger contacts. Figure 27 and Table 31 contain processor marking information.
The processor edge connector defined in this document is referred to as the “SC 242 connector.”
See the Slot 1 Connector Specification (Order Number 243397) for further details on the SC 242
connector.
Note: For Figure 18 through Figure 35, the following apply:
1. Unless otherwise specified, the following drawings are dimensioned in inches.
2. All dimensions provided with tolerances are guaranteed to be met for all normal production
product.
3. Figures and drawings labeled as “Reference Dimensions” are provided for informational
purposes only. Reference Dimensions are extracted from the mechanical design database and
are nominal dimensions with no tolerance information applied. Reference Dimensions are
NOT checked as part of the processor manufacturing. Dimensions in parentheses without
tolerances are Reference Dimensions.
4. Drawings are not to scale.
