    摘要: A method for making small punches by employing multi-layer ceramic (MLC) technology includes the steps of preparing a sublaminate matrix of a high or low sintering temperature material, drilling holes in the sublaminate using a mask as a guide, filling the holes with punch material paste by a solupor process, laminating the sublaminate to a base plate or as a freestanding substrate, firing a laminate at an appropriate sintering temperature and removing the matrix material by a chemical or mechanical method. In accordance with the present invention, a large number of small punches are made in parallel to precise dimensions of two to ten mils in diameter and approximately 100 mils in length. This method allows that a punch plate array can also be used to simultaneously punch an array of vias in a greensheet and eliminates the additional step of loading individual punches into a punch plate, offering cost and time savings.
