The Impact of Housing on the Characteristics of Ceramic Pressure Sensors—An Issue of Design for Manufacturability.
Sensors, 2015, vol. 15, no. 12, pp. 31453–31463
An exploratory study of the impact of housing on the characteristics of a low-temperature
co-fired ceramic (LTCC) pressure sensor is presented. The ceramic sensor structure is sealed in
a plastic housing. This may have non-negligible effect on the final characteristics and should be
considered in the early design phase. The manufacturability issue mainly concerning the selection
of available housing and the most appropriate materials was considered with respect to different
requirements for low and high pressure ranges of operation. Numerical predictions showed the
trends and helped reveal the critical design parameters. Proper selection of the adhesive material
remains an essential issue. Curing of the epoxy adhesive may introduce non-negligible residual
stresses, which considerably influence the sensor’s characteristics.
