Annular Ring Size. Web the annular ring’s ‘size’ is the distance between the outer circle and the inner circle (or, the difference of their radii). Web the pad or land size can be calculated with the simple equation l = a + 2b + c, where a = drill hole (internal) or finished hole (external) diameter, b = minimum annular ring size, and c = fabrication allowance. The annular ring is the ring of via pad area left after drilling;. Web ipc guidelines for the pcb minimum annular ring. Web the sizing parameters of an annular ring include outer diameter (od), drilled hole diameter (d), and annular ring width (w). When drilling vias, a drill wander of 2 mils is expected. Therefore, the annular ring should not be lesser than 2 mils for microvias/laser drills and 4 mils for mechanically drilled vias. Web the size of an annular ring is calculated by the following formula. On the layer’s surface, the area between the finished hole’s diameter and the copper pad’s diameter is what we call an annular ring. An annular ring (ar) in pcb industry is the area of copper pad around a drilled and finished hole. Web the outer ring surrounding the via after drilling process constitutes the annular ring.
