A circuit board standoff for use with SMT placement machinery is provided comprising a hollow substantially cylindrical member, a flange extending from a bottom section of the cylindrical member and an opening positioned in the top section of the substantially cylindrical member operable to receive a fastener. The circuit board standoff operates to provide physical connection between two circuit boards while maintaining a minimum distance there between for inclusion of any required electronic components.

1. A circuit board standoff comprising:a hollow substantially cylindrical member having an elongated middle section, a top section, and a bottom section; a flange extending from the bottom section to provide a substantially flat bottom surface suitable for soldering onto a surface of a circuit board; an opening positioned in the top section of the substantially cylindrical member and operable to receive a fastener; and a tab extending from a section of the bottom surface of the flange, the tab suitable for insertion into an opening in the circuit board. 2. The standoff of claim 1, wherein the tab is operable to be soldered to an underside of the circuit board.3. The standoff of claim 1, wherein the tab is operable to be folded to lie in a position substantially parallel to an underside of the circuit board.4. The standoff of claim 1, wherein the substantially flat bottom surface of the flange includes an area that has been tinned.5. The standoff of claim 4, wherein the substantially flat bottom surface of the flange includes an area that has been tinned with a layer of tin.6. The standoff of claim 4, wherein the substantially flat bottom surface of the flange includes an area that has been tinned with a layer of tin/lead alloy.7. The standoff of claim 4, wherein the substantially flat bottom surface of the flange includes an area that has been tinned with a layer of solder.8. The standoff of claim 1, wherein the elongated middle section is suitable for grasping by a SMT placement machine.9. The standoff of claim 1 further comprising a high temperature adhesive tape affixed to the opening in the top section of the substantially cylindrical member, thus enabling the standoff to be grasped by a vacuum nozzle affixed to a SMT placement machine.10. The standoff of claim 1 further comprising a neck extending from the top section, the neck having a diameter smaller than a diameter of the substantially cylindrical member, the neck having the opening to receive a fastener.11. The standoff of claim 10, wherein an inside surface of the neck is threaded to receive a screw-like fastener.12. The standoff of claim 10, wherein the neck protrudes inside the hollow substantially cylindrical member.13. The standoff of claim 1 further comprising a tab extending from the top section, the tab suitable for insertion into a hole in a second circuit board, the tab operable to be folded to fasten the second circuit board.14. The standoff of claim 1, wherein the top section has a substantially horizontal surface sufficient to receive a section of an underside of a second circuit board.15. The standoff of claim 1, wherein the standoff is made from cold rolled steel.16. The standoff of claim 1, wherein the standoff is suitable for manufacture via a stamping process.17. The standoff of claim 1, wherein the fastener is a rivet.18. The standoff of claim 1, wherein the fastener is a screw.
