-like device to allow the nozzle head to be accurately manipulated in three dimensions, and each nozzle can be rotated around its own axis.

Surface-mount components are placed along the front (and often back) faces of the machine. Most components, large and small are supplied on paper or plastic tape, the tape reels are loaded onto 'feeders', mounted to the machine. Larger ICs are sometimes supplied arranged in trays, which are stacked in a compartment on the machine for this purpose.

Through the middle of the machine there is a conveyor belt, along which unpopulated PCBs travel, and a PCB clamp in the centre of the machine. The PCB is clamped, and the nozzles pick up individual components from the feeders/trays, rotate them to the correct orientation and then place them on the appropriate pads on the PCB with a great deal of precision. Most Placement machines now can optically inspect components on picking, to ensure that the correct component has been picked, that it has been picked successfully and that it is in the correct rotational orientation. The components may be temporarily adhered to the PCB using the wet solder paste
Solder paste

Solder paste is used for connecting the terminations of IC packages with land patterns on the PCB. The paste is applied to the lands by printing the solder using a stencil, while other methods like screening and dispensing are also used....
