Substrate and method of separating components from a substrate
A substrate ( 1 ) having a first groove ( 4 ) is provided with a plurality of protrusions ( 3 ) on the first groove ( 4 ). These protrusions ( 4 ) can have a top with an apex angle of 30 to 150 degrees and results in a controlled breaking of the substrate ( 1 ) and a minimum of loss due to deviations of the crack initiated at the protrusion ( 4 ).
