This article provides information on wave soldering. The wave solder process is characterized by a large number of process parameters. Wave soldering has a number of sub-processes, which include fluxing, preheating, soldering and cooling. Although a good wave soldering machine provides a large number of parameters to optimize each application, the first requisite is good solderability, which requires clean surfaces to be soldered and a good thermal solderability of the assembly. The first parameter to consider is conveyor speed. Any change to the conveyor speed has consequences: It affects the amount of flux applied and influences the temperature profile after preheating. Changing the conveyor speed also affects contact time and cooling.
