Mass production soldering: Mass scale production uses soldering techniques including wave soldering and now more commonly techniques like infrared reflow where the components are mounted on a board and all the components are soldered at the same time.
Small scale production: For small scale production and home construction manual soldering techniques with the use of a soldering iron and solder wire are the most widely used method. Some skill is required to make neat and effective joints, but this can be learned quite easily. This type of soldering technique can be used for making small projects, soldering PCBs, making leads and a host of other applications.
