Robots are ideal for selectively soldering odd-form components, wires and other parts onto printed circuit boards.
Imagine you're a manufacturing engineer at Acme Automotive Assembly Inc., and your company has just landed a big contract to produce electronic brake modules. The module consists of a small circuit board inside a plastic housing. Four metal posts protrude from inside the housing. The circuit board is slipped over these posts and soldered to them.
Reflow and wave soldering are out—the plastic housing cannot take the heat. You could hire a bunch of assemblers to do the job manually, but that could get expensive. Besides, your customer may not appreciate the quality of "Monday morning" solder joints. Fortunately, there is an alternative—robots.
