A crucial element in the SMT assembly process is the use of commercial reflow ovens. These ovens employ a controlled heating and cooling cycle to securely attach components to the PCB. When selecting a service provider, it is advisable to consider the temperature zones of their equipment.
For hobbyist projects or small-scale assembly, a soldering iron can be utilized for soldering tasks. This handheld tool allows precise application of heat to melt solder and establish electrical connections between components and the PCB.
