During this time, a typical SMT assembly line employed two different types of pick-and-place (P&P) machines arranged in sequence. The unpopulated board was fed into a rapid placement machine. These machines, sometimes called chip shooters, place mainly low-precision, simple package components such as resistors and capacitors. These high-speed P ...
Pick and place is the act of picking things up from one location and placing them in another. Specific cases include: picking and placing is one of the major uses of industrial robots; in the context of electronics, SMT placement equipment
A pick and placement machine is a robotic style machine that places some variety of types of components. It includes features such as: component pickup feeder locations, vacuum pickup, vision system, automatic component realignment, repeatable placement accuracy, and transportation system for PCBs.
Motion control – for some applications, such as simple pick-and-place assembly, the robot need merely return repeatably to a limited number of pre-taught positions. For more sophisticated applications, such as welding and finishing ( spray painting ), motion must be continuously controlled to follow a path in space, with controlled ...

Commercial pick and place robots. The delta robot (a parallel arm robot) was invented in the early 1980s by a research team led by professor Reymond Clavel at the École Polytechnique Fédérale de Lausanne (EPFL, Switzerland). [5] After a visit to a chocolate maker, a team member wanted to develop a robot to place pralines in their packages. [6]
