In pcba processing, two common soldering methods are reflow soldering and wave soldering. reflow soldering processes，So what is the role of reflow soldering in pcba processing, and what is the difference between wave soldering and reflow soldering?
(1) Wave soldering is the process of forming molten solder into wave soldering components; reflow soldering is the process of forming high temperature hot air to reflow and melt the solder to the soldered components.
(2) During reflow soldering, there is already solder on the PCB before entering the furnace. After soldering, only the applied solder paste is melted for soldering. When wave soldering, there is no solder on the PCB before it goes into the oven. The solder wave produced by the soldering machine covers the solder. Solder on the pads that need to be soldered.
(3) Reflow soldering is suitable for SMD electronic components, and wave soldering is suitable for pin electronic components.
