As electronic components and integration of different technologies has proliferated, mixed technology assemblies have become far more common. Automotive, medical and other sectors have all integrated mixed technologies as time and progress have radically altered what technology was capable of.
Selective soldering is one of the best assembly methods for mixed technology assemblies, as the installation of multiple component systems requires greater precision than other soldering processes are capable of. Additionally, they can be the only way to complete certain soldering applications necessary for some technologies.
Selective soldering systems are the best choice for electrical components or circuit boards that require soldering through-hole components. Despite surface-mount technology having become much more prevalent, through-hole components have remained in production, especially in electronic components requiring higher power loads.
It can be daunting knowing that selective soldering has to be used with surface mount technology components. Selective soldering systems were designed for use with through-hole components in mind and the process can hold no benefit for SMT components or can potentially be counterproductive.
Soldering is the act of joining two objects by means of melting a soft metal and using that as a bridge, though there are a number of soldering methods employed in making that happen. Which method is employed typically depends on the nature of the objects being joined. The nature of the soldering joint is also important, as each method is usually best reserved for certain specific applications.
