A system for detecting characteristics of a surface includes multiple sources of lights, a platform structure configured to support the surface, a lens aligned with the platform structure, a cropping aperture, and an image receiver. The platform structure is configured to receive light from the source of light and the lens is positioned such that the source of light is not in focus, but the detected surface is in focus. The cropping aperture is configured to crop light reflected from the surface, and the image receiver is configured to receive the light conditioned by the cropping aperture.

Imaging system with defocused and aperture-cropped light sources for detecting surface characteristics

A temperature control device that includes a miniature liquid-cooled heat sink with integral heater and sensing elements is used as part of a system to provide a controlled temperature surface to an electronic device, such as a semiconductor device, during the testing phase. The temperature control device includes an interface surface configured to provide a thermal path from the device to a device under test. One such device has a liquid-cooled heat sink comprising a first heat transfer portion in a first plane and a second heat transfer portion in a second plane. The first and second heat transfer portions establish a three-dimensional cross-flow of coolant within the heat sink structure. An alternate embodiment includes parallel fluid conduits, each having a three-dimensional microchannel structure that directs coolant flow in three dimensions within the fluid conduits. Coolant flows in opposite directions through adjacent fluid conduits, thus resulting in a three-dimensional cross-flow within the heat sink structure.
