摘要： A probe card includes a first probe plate having a first plurality of tapered apertures formed therein. Each of the tapered apertures has a first opening that is smaller than a second opening. The first openings and the second openings are on opposite surfaces of the first probe plate. The probe card further includes a second probe plate having a second plurality of tapered apertures formed therein. Each of the tapered apertures has a first opening that is smaller than a second opening. The first openings and the second openings are on opposite surfaces of the second probe plate. The surfaces having the second openings are disposed adjacent to one another. Pairs of the tapered apertures of the first and second probe plates substantially align. The probe card further includes a plurality of probes, wherein each of the probes is disposed in one of the pairs of the tapered apertures.

摘要： A probe card includes a printed circuit board (PCB) and a probe ring coupled to the PCB. The probe card further includes a plurality of probes coupled to the PCB and to the probe card, and includes a plurality of tubes respectively associated with the plurality of probes. Each tube is configured to surround at least a portion of the probe that the tube is associated with. Each tube includes an inner dielectric portion and an outer conductive portion. The conductive portion of each tube is electrically coupled to the PCB.

摘要： One embodiment relates to an oblique illuminator. The oblique illuminator includes a light source emitting a light beam, a first reflective surface, and a second reflective surface. The first reflective surface has a convex cylindrical shape with a projected parabolic profile along the non-powered direction which is configured to reflect the light beam from the light source and which defines a focal line. The second reflective surface has a concave cylindrical shape with a projected elliptical profile which is configured to reflect the light beam from the first reflective surface and which defines first and second focal lines. The focal line of the first reflective surface is coincident with the first focal line of the second reflective surface. The first and second focal lines of the second reflective surface may be a same line in which case the elliptical curvature is a projected spherical profile. Other embodiments, aspects and features are also disclosed.
