The global transition to lead-free (Pb-free) electronics has led component and equipment manufacturers to transform their tin–lead (SnPb) processes to Pb-free. At the same time, Pb-free legislation has granted exemptions for some products whose applications require high long-term reliability. However, due to a reduction in the availability of SnPb components, compatibility concerns can arise if Pb-free components have to be utilized in a SnPb assembly. This compatibility situation of attaching a Pb-free component in a SnPb assembly is generally termed "backward compatibility." This paper presents the results of microstructural analysis of mixed solder joints which are formed by attaching Pb-free solder balls (SnAgCu) of a ball-grid-array component using SnPb paste. The experiment evaluates the Pb phase coarsening in bulk solder microstructure and the study of intermetallic compounds formed at the interface between the solder and the copper pad.

PCI Express brought about a whole new series of challenges for designers and the next generation. PCI Express 2.0 takes the challenges to a new level. Doubling the speed of the link to 5 GT/s, while maintaining backwards compatibility with PCI Express 1.0 potentially opens up interoperability issues. This presentation describes the methods and tools required to validate PCI Express 2.0 designs.
