A printed circuit board (PCB) assembly consists of a circuit board and a variety of components in different shapes and sizes placed at specific locations on the board. They are used extensively in a variety of products by many industries today. These products include, for example, computer terminals, televisions, electronic instruments, and process controllers. There are many types and models of automatic machines available for placing components on the boards. The component placement operation consists of all steps necessary to remove a component from its packaging materials and mount it onto the PCB. The components are supplied either from a set of feeders, magazines or matrix trays. Because of the extreme accuracy required, automatic equipment is mandatory for all but the smallest production volumes.
