Abstract: Low temperature co-fired ceramics (LTCC) package can assemble and integrate different kinds of chips and other components into the same package to realize some functions of the system, which is important means to realize the miniaturization, integration, multi-function and high reliability of the system. The packaging methods of LTCC substrate, and expounds the characteristics and research status of LTCC substrate metal shell packaging, pin grid array (PGA) packaging, ball grid array (BGA) packaging, leadless through-wall package, quad flat package (QFP) packaging, leadless chip carrier (LCC) packaging and 3D-MCM packaging technology are summarized. Some key technical factors affecting the airtightness and reliability of LTCC substrate packaging are analyzed, and the development trend of LTCC packaging technology is prospected.
