After the C4 solder bump is reflowed, epoxy (encapsulant) is under-filled between the
die and the substrate. Under-fill material is commonly used on large high-power die;
however, this is not a requirement of the C4 technology. The package substrate is a
multilayer-co-fired ceramic. The package-to-board interconnection is via an array of
orthogonal 90/10 (lead/tin) solder balls on 1.27 mm pitch. During assembly of the
C4/CBGA package to the board, the high-melt balls do not collapse.

Internal Package Conduction
Resistance
For the C4/CBGA packaging technology, the intrinsic conduction thermal resistance
paths are as follows:
the die junction-to-case thermal resistance
the die junction-to-lead thermal resistance
These parameters are shown in Table 12. In the C4/CBGA package, the silicon chip is
exposed; therefore, the package case is the top of the silicon.
Figure 6 shows a simplified thermal network in which a C4/CBGA package is mounted
on a printed-circuit board.

Note:
Internal package resistance differs from external package resistance.
