Abstract
A pressure sensor assembly is disclosed wherein the substrate to which the pressure sensing die is mounted is decoupled from the package.
Claims20
A pressure sensor assembly for measuring the pressure of a fluid comprising:
- a first member;
- a second member comprising a first end coupled to the first member and a second end coupled to the source of the fluid;
- a substrate located in a first cavity formed between the first member and the second member, wherein a first side of the substrate faces a second side of the first member and a second side of the substrate faces a first side of the second member;
- a pressure sensing die mounted to the substrate;
- and
- a first energy absorbing member between the first side of the substrate and the second side of the first member, wherein the first energy absorbing member decouples the substrate from the first member.
