Advanced soldering processes
Abstract
Advanced soldering processes are discussed in a complete manner. The ability to meet the needs of electronic manufacturing, while addressing the environmental issues are challenging goals. Government regulations mandate the elimination of most solvents in solder flux removal. Alternative approaches to promoting wetting are discussed. Inert atmosphere soldering, acid vapor fluxless soldering, atomic and ionic hydrogen as reactive atmospheres, fluxless laser soldering in a controlled atmosphere are offered as soldering mechanisms for the future. Lasers are discussed as alternate heat sources. Various types of lasers, advantages of lasers, and fiber optic beam delivery are considered.
