This article provides a discussion on binary alloy phase diagrams published in this handbook. All diagrams presented are for stable equilibrium conditions, except where metastable conditions are indicated.

Resistance soldering (RS) can be applied to electrically conductive materials that allow the passage of electric current. The process can be used for selective spot soldering of small components, for the soldering of closely placed parts on an assembly, or for heat restriction when necessary. This article explains that the RS process can be used in all soldering operations and with all solderable metals. It provides information on the applications, preassembly practices, the equipment used and the training required for soldering personnel.

This article focuses on the various types of corrosion-related failure mechanisms and their effects on passive electrical components. The types include halide-induced corrosion, organic-acid-induced corrosion, electrochemical metal migration, silver tarnish, fretting, and metal whiskers. The passive electrical components include resistors, capacitors, wound components, sensors, transducers, relays, switches, connectors, printed circuit boards, and hardware.
