This article presents an introduction to brazing, including information on its mechanics, advantages, and limitations. It reviews soldering with emphasis on chronology, solder metals, and flux technology. The article also provides useful information on mass, wave, and drag soldering. It presents a table which contains information on the comparison of soldering, brazing, and welding.

This article focuses on the design considerations and process parameters critical to the successful implantation of wave soldering on printed circuit boards. The design considerations include the through-hole technology and the surface-mount technology. The article presents information on process parameters, which can be divided into three groups: the fluxing operation, solder wave properties, and process schedule. It provides information on various solder defects.
