Abstract
A method for affixing pins to a ceramic substrate substantially eliminating cracking of the substrate by pre-bulging the pin blanks and, then after inserting the pin blanks into the substrate, a clearance is provided between the lower pin holding die and the lower face of the substrate for the subsequent head forming operation on the opposite face of the substrate.
