Abstract

Un procédé de courant pulsé et un appareil pour passer un courant électronique pulsé à travers un substrat pour briser et percer le substrat. Une pointe de foret a un ensemble délectrodes avec au moins deux électrodes et un espace entre les électrodes. Au moins une des électrodes est mobile par rapport à lautre électrode pour être continuellement en contact avec ou à proximité du substrat à briser pour que le courant puisse passer à travers le substrat. Un câble connecte les électrodes à un générateur dimpulsions et un fluide de rinçage est alimenté à la pointe du foret. Un ensemble de tiges de forage comprend et supporte lensemble délectrodes et procure une commande directionnelle de la pointe de foret tout en forant. Lensemble de tige de forage peut comprendre un condensateur pour offrir au moins une partie de lalimentation de courant électrique à la pointe de foret.
