A substrate, preferably constructed of a ductile material and a tool having the desired shape of the resulting device for contacting contact pads on a test device is brought into contact with the substrate. The tool is preferably constructed of a material that is harder than the substrate so that a depression can be readily made therein. A dielectric (insulative) layer, that is preferably patterned, is supported by the substrate. A conductive material is located within the depressions and then preferably lapped to remove excess from the top surface of the dielectric layer and to provide a flat overall surface. A trace is patterned on the dielectric layer and the conductive material. A polyimide layer is then preferably patterned over the entire surface. The substrate is then removed by any suitable process.
We claim: 1. A probing assembly for probing an electrical device comprising: (a) a rigid support: (b) a membrane assembly having a region overlying said support; (c) a plurality of elongate non-upright contacts supported by said region, each of said contacts having a length and a contacting portion
We claim: 1. A probing assembly for probing an electrical device comprising: (a) a rigid support: (b) a membrane assembly having a region overlying said support; (c) a plurality of elongate non-upright contacts supported by said region, each of said contacts having a length and a contacting portion spaced apart from the axis of moment of said contact, and each contact being electrically connected to a corresponding conductor that extends into said region; (d) a control mechanism operating in respect to each contact to urge each contact, when placed into pressing engagement with said electrical device, into tilting motion so that different portions of each contact move different distances relative to said support so that each contact is driven in accordance with said tilting motion into lateral scrubbing movement across said electrical device, and each contact remaining supported by said membrane assembly along substantially all of said length during the tilting motion; (e) wherein said contacts are formed by depositing conductive material in a depression in a sacrificial substrate by pressing a tool against a surface of said ductile substrate. 2. The probing assembly of claim 1 wherein each one of said contacts is tiltable substantially independently of the other ones of said contacts. 3. The probing assembly of claim 1 including a base, said support being tiltably coupled to said base so as to enable said support to automatically tilt relative to said base toward a position parallel to said electrical device in response to pressing engagement between respective ones of said contacts and said electrical device. 4. The probing assembly of claim 1 wherein each contact includes a contact bump fixedly joined in off-centered location on said contact. 5. The probing assembly of claim 1 wherein said contacts are provided in pairs and the respective lateral scrubbing movements of said contacts in each pair are in opposite directions. 6. The probing assembly of claim 1 wherein the distance of said lateral scrubbing movement of each contact after touchdown on said electrical device is uniformly dependent for each contact on the distance traveled after touchdown. 7. The probing assembly of claim 1 including an elastomeric member interposed between each contact and said support. 8. The probing assembly of claim 2 wherein said contacts are arranged by rows and columns. 9. The probing assembly of claim 1 wherein each contact is joined in overlapping relationship to the corresponding conductor. 10. The probing assembly of claim 1 wherein said membrane assembly is substantially continuous along said region. 11. The probing assembly of claim 1 wherein each contact is supported by a continuous portion of said membrane assembly.
