Abstract: A method for fixing a pin to a ceramic substrate includes inserting the pin into a hole through the thickness of the substrate, restraining one end of the pin that extends from one surface of the substrate, and striking the end of the pin at the opposite end of the substrate with a force sufficient to form a head on the pin and to cause permanent radial expansion of the pin against the surface of the hole in the substrate.
