SINTERING METHO OF LOW TEPERATURE CO-FIRED CERAMICS

摘要

PURPOSE: A method for sintering low temperature co-fired ceramics(LTCC) is provided to prevent the sintering-shrinkage of the ceramics to the x-y axial direction by arranging restricting layers on the upper and/or the lower side of an LTCC layer. CONSTITUTION: A method for sintering an LTCC includes the following: An LTCC layer(2) and one or more restricting layers(3, 4) which form a stacked body. The restricting layers are based on alumina, zirconia, or a mixture of the same and are arranged on the upper side and/or the lower side of the LTCC layer. One or more rods are arranged on the upper side of the stacked body, and the stacked body with the rods is sintered at a temperature between 830 and 900 degrees Celsius for 20-40 minutes. The sintering temperature of the restricting layers is higher than that of the LTCC layer. The restricting layers and the rods are eliminated after the sintering process.
