Microchips for downhole data collection
A microchip includes a PCB, a first contact feature positioned along a first area of the PCB, a second contact feature positioned along a second area of the PCB that is disposed opposite the first area, a contact frame including first and second contact members respectively coupled to the first and second contact features for signal communication between the first and second contact features and an external electronic device, and a housing enclosing an interior region of the microchip and carrying the first and second contact members of the contact frame.
1. A microchip, comprising:
a printed circuit board (PCB) disposed within an interior region of the microchip;
a first contact feature positioned along a first area of the PCB within the interior region;
a second contact feature positioned along a second area of the PCB that is disposed opposite to the first area and within the interior region;
a contact frame comprising:
a first contact member and a second contact member respectively coupled to the first contact feature and to the second contact feature for signal communication between the first and second contact features and an external electronic device, and
a reinforcement member to which the first and second contact members are directly attached such that the reinforcement member provides structural support for an arrangement of the first and second contact members, the reinforcement member being disposed within the interior region and surrounding the PCB; and
a housing carrying the first and second contact members and enclosing the interior region and the reinforcement member,
wherein the reinforcement member has a same cross-sectional shape as the housing and extends about an inner surface of the housing along an entire circumference of the housing such that the reinforcement member further provides structural support for the housing.
2. The microchip of claim 1 , wherein the reinforcement member is positioned along a horizontal plane of the PCB.
3. The microchip of claim 1 , wherein the reinforcement member is positioned along a vertical plane of the PCB.
4. The microchip of claim 1 , wherein the reinforcement member is attached to the first and second contact members along a peripheral edge of the PCB.
5. The microchip of claim 1 , wherein the first and second contact members are carried by the reinforcement member respectively at first and second locations that are spaced apart from the PCB such that the first and second contact members are not directly connected to the PCB.
6. The microchip of claim 5 , wherein the contact frame further comprises first and second electrodes that respectively extend between the first and second contact members and the first and second contact features positioned along the PCB.
7. The microchip of claim 1 , wherein the reinforcement member is a first reinforcement member, and the contact frame further comprises one or more additional reinforcement members that surround the PCB and that are oriented perpendicular to the first reinforcement member.
8. The microchip of claim 1 , wherein the reinforcement member comprises a non-conductive ring.
9. The microchip of claim 1 , wherein the first and second contact members of the contact frame are directly connected to the first and second contact features positioned along the PCB.
10. The microchip of claim 1 , wherein the first and second areas of the PCB are disposed along a peripheral edge of the PCB.
11. The microchip of claim 1 , wherein the first and second areas of the PCB are disposed along an interior region of the PCB.
12. The microchip of claim 1 , wherein the contact frame further comprises third and fourth contact members respectively coupled to third and fourth contact features positioned along the PCB for signal communication between the third and fourth contact features and the external electronic device.
13. The microchip of claim 12 , wherein the first, second, third, and fourth contact members are spaced about 90 degrees apart from one another about a circumference of the housing.
14. The microchip of claim 1 , wherein exterior surfaces of the first and second contact members are disposed flush with an exterior surface of the housing.
15. The microchip of claim 1 , wherein the housing has a substantially spherical exterior shape.
16. The microchip of claim 15 , wherein the reinforcement member comprises a non-conductive ring that extends about a circumference of the housing to provide structural support for the housing.
17. The microchip of claim 1 , wherein the microchip comprises an equal number of contact features and contact members such that each contact member is dedicated to a respective contact feature.
