**3. Pulse co- electrodeposition of Sn based composites**

Initially, the pulse electrodeposition was used for decorative and jewellery applications to improve the surface appearance and shine, wear and friction, fretting corrosion resistance.[42] Recently, more attention has been paid to incorporate different nanoparticles to obtain much improved properties. There are various processing parameters in electrodeposition that affect the particle incorporation in composite deposits, such as (1) particle type, size, and shape; (2) bath pH, constituents, additives, and aging; (3) deposition variables, such as particle concen‐ tration in bath, current density, agitation, pulsing methods, and temperature.[42–44]


**Table 1.** Nanocomposite solder produced by various routes

The different nanocomposite solders produced in literature are shown in Table 1. The compo‐ site approachhas beendevelopedmainly to improve the strengthandreliability of solderjoints. Nano-sized reinforcement particles in conventional solder matrices due to their effectiveness in improving the reliability by spreading the stress uniformly in the matrix.[19, 45, 46]

In this chapter, an effort has been made to discuss the strength related concerns by incorpo‐ rating the reinforcement nanoparticles within the solder matrix using co-electrodeposition process.
