Solder joints wetted with solder are heated up to soldering temperature in a precisely defined temperature-time profile of the assembly.
Soldering methods are divided based on different aspects (according to DIN 8505). People differentiate between soft soldering and hard soldering.
Flame soldering is a thermal joining process for metallic materials that are connected with a solder during this method.
Furnace brazing is a soldering method in which the parts to be joined are heated in an oven with the brazing solder inside, and which is preferably used for hard soldering.
Hand soldering is the easiest and most common soldering method in electronic engineering.
