A METHOD OF MAKING A BASE FOR A PRINTED ELECTRIC CIRCUIT WHICH INCLUDES THE STEPS OF FORMING A PRINTED CIRCUIT INCLUDING A HOLE ON A CARRIER, THEN APPLYING A LAYER OF RESINOUS MATERIAL ON SAID CARRIER OVER THE PRINTED CIRCUIT, FORCING A DIE HAVING AN OUTWARDLY PROTRUDING PART THEREON THROUGH SAID LAYER TO NLATERALLY DISPLACE PORTIONS OF SAID MATERIAL AND TO FORM A SECOND HOLE IN SAID LAYER WHICH IS IN REGISTRY WITH THE FIRST-NAMED HOLE AND TO REMOVE MATERIAL AWAY FROM SELECTED PORTIONS OF SAID PRINTED CIRCUIT BY MEANS OF SAID OUTWARDLY PROTRUDING PART WHILE LEAVING A FLASH AT THE BOTTOM OF THE SECOND HOLE, DISENGAGING THE DIE FROM SAID MATERIAL, THEN SOLIDIFYING SAID MATERIAL, REMOVING SAID FLASH SO THAT THE TWO FIED MATERIAL, AND REMOVING SAID FLASH SO THAT THE TWO HOLES MERGE INTO ONE HOLE, LEAVING THE PRINTED CIRCUIT EMBEDDED IN THE SOLIDIFYING MATERIAL AND FORMING AT LEAST A PART OF THE PERIMETER OF THE MERGED HOLE.
