Printed Circuit Board assembly sometimes called PCB Assembly(PCBA).
The bare board is populated with Electronic Components to form a functional. In through-hole technology, the component leads are inserted in holes surrounded by conductive pads; the holes keep the components in place. In surface-mount technology (SMT), the component is placed on the PCB so that the pins line up with the conductive pads or lands on the surfaces of the PCB; solder paste, which was previously applied to the pads, holds the components in place temporarily; if surface-mount components are applied to both sides of the board, the bottom-side components are glued to the board. In both through hole and Surface Mount, the components are then soldered; once cooled and solidified, the solder holds the components in place permanently and electrically connects them to the board.
