Abstract
In this paper, Via hole pore were investigated during PLAS (PessureLess Assisted Constrained Sintering) process of LTCC. Ag and Ag-Pd paste mixture were tested for via paste. Ag paste with 10~25% Ag-Pd paste showed no via hole pore, but further increase of Ag-Pd contents in via paste increased via pore. From shrinkage curve, 10~25% Ag-Pd paste showed expansion behaviors before shrink and this phenomena result in the reduction of via hole pore during PLAS process.
