Abstract:
1. A charge system for destroying a substrate comprising: a first substrate having a number of recesses formed therein with each of the recesses having a housing disposed therein; a high density charge disposed within the housing with a number of recesses formed within the high density charge; a number of low density charges disposed within each of the recesses formed within the high density charge; a second substrate located proximate to the first substrate; and a boundary formed in the first substrate located between the high density charge and the second substrate, wherein the housing has a bottom with a number of apertures formed therein that are structured to receive an energy supply for contact with the low density charge, wherein the low density charge is structured to be ignited with the energy supply, wherein the high density charge is structured to be ignited from the low density charge after the low density charge has been ignited, wherein the low density charge and the high density charge are structured to destroy the second substrate after ignition, and wherein the first substrate is a circuit board and the second substrate is a chip.
