Description

technical field [0001] The invention relates to a SMD quartz crystal resonator base and a processing method thereof, belonging to the technical field of SMD quartz crystal resonator structures. Background technique [0002] At present, there are two base structures of SMD quartz crystal resonators. One is the metal package structure: sintering the metal ring of Kovar material on the multi-layer ceramic board, and then sealing and welding the cover plate in parallel. The disadvantage is that the price is high; the other is the glass glue package. Structure: The single-layer ceramic plate and the metal shell or ceramic cover are sealed with glass glue. The disadvantage is that the glass glue has a small amount of gas volatilization, which affects the aging rate of the product. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the multilayer ceramic board of the existing SMD quartz crystal resonator is difficult to process a...
