    Abstract: Improved wafer-scale testing of optoelectronic devices, such as CMOS image scan devices, is provided. A probe card includes an LED light source corresponding to each device under test in the wafer. The LED light sources provide light from a phosphor illuminated by the LED. A pinhole and lens arrangement is used to collimate the light provided to the devices under test. Uniformity of illumination can be provided by closed loop control of the LED light sources using internal optical signals as feedback signals, in combination with calibration data relating the optical signal values to emitted optical intensity. Uniformity of illumination can be further improved by providing a neutral density filter for each LED light source to improve uniformity from one source to another and/or to improve uniformity of the radiation pattern from each LED light source.

    Abstract: A probe card assembly can comprise a guide plate comprising probe guides for holding probes in predetermined positions. The probe card assembly can also comprise a wiring structure attached to the guide plate so that connection tips of the probes are positioned against and attached to contacts on the wiring structure. The attachment of the guide plate to the wiring structure can allow the wiring structure to expand or contract at a greater rate than the guide plate. The probes can include compliant elements that fail upon high electrical current and thermal stresses located away from the contact tips.

    Abstract: Wafer cassette systems and methods of using wafer cassette systems. A wafer cassette system can include a base and a probe card assembly. The base and the probe card assembly can each include complementary interlocking alignment elements. The alignment elements can constrain relative movement of the base and probe card assembly in directions parallel to a wafer receiving surface of the base, while permitting relative movement in a direction perpendicular to the receiving surface.

    Abstract: A stiffener for a probe card assembly can include decoupling mechanisms disposed within radial arms of the stiffener. The decoupling mechanisms can be compliant in a direction along a radial direction of said radial arm and rigid in a direction perpendicular to said radial arm. The decoupling mechanisms can decouple the stiffener from thermally induced differential radial contraction and expansion of the stiffener relative to the cardholder to which the stiffener is mounted. This can reduce thermally-induced vertical translation of the probe card assembly.

    Abstract: One or more customization layers can be added to a wiring substrate. The customization layers can provide customized electrical connections from electrical contacts of the base wiring substrate to electrical contacts at an outer surface of the customization layers, which can allow the contacts at the outer surface of the customization layers can be in a different pattern than the contacts at the surface of the base wiring substrate. The customization layers can comprise electrically insulating material, electrically conductive via structures through the insulating material, electrically conductive traces, electrically conductive jumpers electrically connecting two traces without contacting a trace disposed between the two traces, and/or other such elements. A jumper can be formed by making a relatively small deposit of electrically insulating material between the two traces to be connected and then making a relatively small deposit of electrically conductive material on parts of the two traces and the insulating material. Via structures can be coupled to traces and an insulating material can be cast around the via structures. Alternatively, via structures can be formed in openings with sloped side walls in an insulating layer.

The probe card assembly can also include probes located at a first side of the probe card assembly. The probes, which can be electrically connected to the electrical interface, can be configured to contact terminals of the electronic devices in the test system while the probe card assembly is attached to the test system. The probe card assembly can be configured to impede thermal flow from the probe card assembly to the test system at places of physical contact between the probe card assembly and the test system while the probe card assembly is attached to the test system.
