Abstract
A printed circuit board assembly (PCBA) waveguide assembly comprises a PCBA, a waveguide, and a spring-loaded rivet. The spring-loaded rivet comprises a rivet head, a rivet shank, a rivet tail, and a spring element and fastens the PBCA to the waveguide. The spring element provides flexibility in the clamping force of the rivet to accommodate thermal expansion and contraction, creeping and shear forces experienced by the PCBA and waveguide.
Claims20
A printed circuit board assembly (PCBA) waveguide assembly, comprising:
- a PCBA;
- a waveguide;
- and
- a spring-loaded rivet comprising a rivet head, a rivet shank, a rivet tail, and a spring element;
- wherein the spring-loaded rivet fastens the PBCA to the waveguide.
A spring-loaded rivet, comprising:
- a rivet head;
- a rivet shank;
- a rivet tail;
- and
- a spring element positioned around the rivet shank;
- wherein the spring-loaded rivet fastens a first component to a second component.
A method for installing a spring-loaded rivet in a printed circuit board assembly (PCBA) waveguide assembly, comprising:
- inserting the spring-loaded rivet into a rivet channel through the PCBA and extending into the waveguide until the rivet tail is positioned in a rivet chamber in the waveguide;
- and
- deforming the rivet tail in the rivet chamber until the rivet is fully installed and clamps the PCBA and the waveguide together;
- wherein deforming the rivet tail partially compresses a spring element positioned around a shank of the spring-loaded rivet and between a head of the rivet and the PCBA.
