Abstract: In order to promote the localization process of low-temperature co-fired ceramic (LTCC) green tapes, and systematically and deeply study the process performance and engineering application of domestic LTCC green tapes, taking imported LTCC paste and independently developed G200 type LTCC green tape as the research objects, LTCC process is used to make test substrate, and a series of application verification experiment schemes are designed to test and study the key properties of G200 type LTCC green tape, such as printing accuracy, dimensional stability, sintering shrinkage rate and paste co-firing compatibility. By optimizing the preheating process, conductor printing and other process parameters, selecting the appropriate substrate amplification factors and the number of substrate layers, the LTCC substrate products produced can meet the practical application requirements.
