Probing assembly for testing integrated circuits
View Patent ↗A probing assembly is disclosed. The probing assembly includes an interface board, a structural support element, a trace support element and a probe support element. The structural support element provides structural and mechanical support to the trace support element. The trace support element includes a body and multiple trace lines located on the body. The probe support element includes a plate having multiple guide holes in which micro probes are inserted. At least one of the micro pins is in contact with one of the trace lines within the trace support element. A set of rails are utilized to secure the probe support element, the trace support element and the structural support element to the interface board.
1. A probing assembly comprising:
an interface board;
a trace support element having a body and a plurality of trace lines on said body;
a structural support element for providing structural and mechanical support to said trace support element;
a probe support element having a plate with a plurality of guide holes in which a plurality of micro pins are inserted, wherein each of said plurality of micro pins has one end larger than the diameter of said guide holes to prevent said plurality of micro pins from passing through said guide holes, wherein at least one of said micro pins has its said larger end in contact with one of said trace lines within said trace support element; and
a plurality of rails for securing said probe support element, said trace support element and said structural support element to said interface board.
2. The probing assembly of claim 1 , wherein said trace support element has a center opening.
3. The probing assembly of claim 1 , wherein said trace support element is made of a flexible electrical insulating membrane.
4. The probing assembly of claim 1 , wherein said trace support element is made of a polymide film.
5. The probing assembly of claim 1 , wherein said trace lines are made of beryllium copper.
6. The probing assembly of claim 1 , wherein said structural support element is made of an electrical insulating material.
7. The probing assembly of claim 1 , wherein said structural support element is made of polyamide-imide.
8. The probing assembly of claim 1 , wherein said structural support element is made of polyetheretherketone.
9. The probing assembly of claim 1 , wherein said structural support element is in a pyramidal shape configured to couple with said trace support element.
10. The probing assembly of claim 1 , wherein said at least one micro pin has its other end configured to directly contact a device under test.
