Wave and selective soldering form connections on through-hole and suitable mixed-technology assemblies. Wave soldering passes boards over a solder wave, while selective soldering applies solder to programmed locations using equipment suited to the joint layout.
The methods serve different production needs. A wave process can solder many accessible connections together, whereas selective soldering offers localized access on boards with areas that should avoid the solder bath. Component layout, pallet requirements and thermal exposure influence the choice.
Both processes depend on compatible solder alloy, flux application and preheating. Board transport and cooling also affect joint quality. Compare the complete production sequence, including fixtures, changeovers and inspection, when assessing capacity. Trials on representative assemblies help identify access restrictions and establish suitable process parameters.

Selective soldering applies molten solder to defined locations on a PCB, typically to form through-hole connections on mixed-technology assemblies. Programmed local soldering helps avoid areas that should not be exposed to a full solder wave.
A typical process combines selective fluxing, preheating and controlled solder contact. Nozzle size and access are important because nearby components can restrict the path to a joint. Board support and positioning help maintain the intended relationship between the assembly and soldering tool.
Evaluate the number and arrangement of joints as well as the required output. A system’s nominal speed does not account for every movement, dwell or heating step. Product changeovers, nozzle maintenance and flux handling affect daily operation. Process development should use representative boards and verify the resulting joints against the assembly requirements.
