A Printed Circuit Board (PCB) consists of a sheet of an insulating material. Small holes are provided on this sheet for accommodating different components of the circuit to be assembled. The components are automatically connected with each other through copper strips embedded within the sheet (Fig. 1).

Design for manufacturing ¡s a new technique of designing. Manufacturability of PCBs depends upon its design. In a normal manufacturing process data flows only in one direction, i.e., ‘from design to manufacturing’ but DFM ensures that the date flows ‘from manufacturing to design’ also. This gives improved manufacturability of a board.
