Pressure sensor with improved heat dissipation characteristics

A pressure sensor, comprising:

• a housing having an electrically conductive member encapsulated therein:
• an opening formed in said housing, a portion of said electrically conductive member being disposed in said opening;
• a sensor die comprising a first surface and a second surface, said first surface having a plurality of electronic components formed thereon, said first surface of said sensor die further comprising a contact portion and a diaphragm portion;
• first means for connecting said diaphragm portion in fluid communication with a first pressure;
• an elastomeric member having a thermally conductive portion, said thermally conductive portion being electrically nonconductive;
• said thermally conductive portion being disposed in contact with said plurality of components and in contact with said electrically conductive member;
• and
• means for urging said sensor die, said elastomeric member and said electrically conductive member together.

A pressure sensor, comprising:

• a housing having a electrically conductive member attached thereto;
• a sensor die having a first surface and a second surface, a plurality of electronic components being formed on said first surface;
• an elastomeric member having a first portion which is thermally conductive and electrically insulative, said first portion being disposed in contact with said plurality of electronic components and with said electrically conductive member, said first surface further comprises a contact portion and a diaphragm portion, said elastomeric member further comprises a selectively conductive portion and a cavity portion, said cavity portion being disposed in contact with said diaphragm portion, said selectively conductive portion being disposed in contact with said contact portion;
• means for compressing said elastomeric member between said sensor die and said electrically conductive member
• first means for connecting said diaphragm portion in fluid communication with a first pressure;
• and
• second means for connecting said cavity portion in fluid communication with a second pressure.
