Patent ID: 6886247

Claim:
A singulation method comprising: providing a circuit board substrate assembly comprising a substrate material having first and second opposed edges, the substrate material comprising: a plurality of circuit forming regions comprising at least one pair of adjacent circuit forming regions; a first interconnection region and a second interconnection region, wherein the first interconnection region extends along the first edge and is located between the first edge and the plurality of circuit forming regions, wherein the second interconnection region extends along the second edge and is located between the second edge and the plurality of circuit forming regions; and at least one opening defined in the substrate material between each pair of adjacent circuit forming regions, wherein the at least one opening extends into at least portions of both the first interconnection region and second interconnection region; removing at least a portion of the first and second interconnection regions along a respective first and second singulation axis defined therein parallel to one another to singulate at least two circuit forming regions of the plurality of circuit forming regions, the first singulation axis and the second singulation axis intersecting with the at least one opening defined between each pair of adjacent circuit forming regions.
