With sufficient stress on the external pads, they can be pulled toward the plated through hole during thermal stress and subsequently appear lifted from the surface upon cooling These lifted or rotated pads are an indication of excessive thermal expansion Thermal cycling over time can fatigue the plated through hole and ultimately cause failure from cracking of the copper plated within the hole or separation of the conductor from the hole wall Thermal expansion in the x/y axes is of more importance when discussing the attachment of components to the printed circuit This is of particular importance when chip scale packages (CSPs) and direct chip attach components are used because the difference in thermal expansion between the printed circuit board and the component can compromise the reliability of the bond between them as they undergo thermal cycles.

The x/y CTE can also impact interlaminar adhesion and delamination resistance in copper clad laminates or PCBs If individual layers of materials with very different x/y CTE properties are adjacent to each other, thermal cycling or thermal excursions can cause enough stress at the interface of these layers to cause a separation or delamination The thermal excursions experienced in PCB assembly processes can severely stress these interfaces, and the higher temperatures of leadfree assembly result in additional stress For this reason, more attention should be given to the x/y CTE values of individual layers in a PCB that will experience lead-free assembly With a given material type, this typically means that the choice of fiberglass cloth styles and resin contents adjacent to each other be examined Furthermore, hybrid constructions,.

In Chap. 58, the critical design variables that could impact the reliability and manufacturability of printed circuit assemblies (PCAs) have been outlined. The use of various assessment tools to quantify the expected life of PCAs is an important aspect of design for reliability. Data collected from standard tests can be used with acceleration transforms and finite element analysis to assess the expected service life of any interconnect. Experimental data play a crucial role in reliability assessments. Poor data or data obtained under incorrect experimental conditions can lead to grossly inaccurate reliability assessments. Garbage in equals garbage out is nowhere more true than in interconnect reliability assessments. The history and experience gained over years of use of tin-lead solders are no longer applicable to leadfree assemblies because lead-free solders behave differently under the same end-use conditions and relatively little data are available on the characteristics of lead-free solders. The formulas for predicting the field life of solder joint interconnects would have to be revisited and validated with extensive experimental data. Moreover, the introduction of lead-free materials is accompanied by new failure mechanisms that are yet to be fully understood and mapped into field-life prediction models. 59.1.1 Experimental Tests The different levels of solder joint interconnects in a typical PCA are illustrated in Fig. 59.1. A myriad of experimental tools have been developed to assess solder joint reliability rapidly. These include:

FIGURE 59.1 First-, second-, and third-level interconnects defined, employing a flip-chip assembly as an example. The first-level interconnect is the primary connection between the silicon die and the package substrate. In this example, the connection is created by the solder bumps between the die and the package. The second-level interconnect in this example is the next level of connection between the package substrate and the module substrate. The third-level interconnect in this example is created when the solder balls on the bottom side of the module substrate are attached via surface-mount technology (SMT) to the printed wiring board (PWB).
