ABSTRACT:
A pressure sensor package is claimed. The pressure sensor package includes a pressure sensor base having a cavity, a pressure sensor diaphragm positioned over the cavity, and a pressure sensor cap positioned over and secured to the pressure sensor base. The pressure sensor cap further includes a deformed portion securing the cap to the base, an engaging portion adapted to allow engagement of the cap when the deformed portion is being deformed around the base, an upper portion between the engaging portion and the diaphragm, and a lower portion between the engaging portion and the deformed portion, wherein the upper portion is longer than the lower portion. The engaging portion may extend radially outwardly from the cap, such as in the form of an annular ledge.
