ABSTRACT:
This invention relates to a ceramic module and to methods for forming protruding, upstanding electrically conducting pins by the selective abrasion of a surface 18 of a multilayered ceramic module 10. An abrasive blasting device 40 is disposed adjacent to the surface 18 for directing a stream of abrasive particles 42 against the surface. The particles 42 strike both metallic conductors 20 and 22 and also the ceramic material of the layer 14. Inasmuch as the ceramic material is relatively hard and brittle as compared to the ductile metallic conductors the abrasive particles 42 abrade away the ceramic layer 14 at a faster rate than the ductile metallic material of the conductors 20 and 22. The abrasive particles 42 may be comprised of any suitable abrasive, such as Al.sub.2 O.sub.3, SiC or WC. The module may be rotated beneath a nozzle of the grit blasting device, the nozzle being linearly translated above the surface being abraded.
