Abstract
Systems and methods for sensing obstructions associated with electrical testing of microfeature workpieces are disclosed. An apparatus in accordance with one embodiment includes a first support member configured to releasably carry a microfeature workpiece, a second support member positioned proximate to the first support member and configured to carry an electrical testing device, wherein at least one of the first and second support members is movable toward and away from the other. The apparatus can further include a signal source (e.g., radiation source) positioned proximate to the support member, and a signal sensor (e.g., a radiation sensor) positioned at least proximate to the first support member and the signal source. The signal sensor can be configured to received at least a portion of the signal directed by the signal source and passing proximate to the first support member. Accordingly, the signal source and signal sensor can be used to detect obstructions carried by the first support member and/or the microfeature workpiece.
