A Flat Capacitance Material and Its Preparation Method for MEMS Microphone Chips
In order to solve the technical difficulties such as relatively large volume and poor EMC (ElectroMagnetic Compatibility) of MEMS (Micro-Electro-Mechanical System) microphone chips
as well as the parasitic capacitance and inductance introduced by chip connections
soldering points
etc.
research is conducted on flat capacitance materials and their preparation methods. The flat capacitance material FCM1121 prepared in this study
compared with mainstream products in the field of flat capacitance materials
endows MEMS microphone chips with equally excellent basic performance
as well as better RF (Radio Frequency) anti-interference and other performance advantages. It also provides good reference opinions for the research and development of flat capacitance materials in other fields.
