In assembly the bare board is populated with electronic components, called a "printed circuit board assembly" (PCBA). In through-hole technology, the component leads are inserted in holes surrounded by conductive pads; 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.

What is the right way to count the opportunities for defects in order to calculate the quality (in ppm) of SMT assembly processes as well as the quality of the PCB's?
