Section: claims

1. A micro testing and assembly device comprising: A) a scanning electron microscope;  B) an operating chamber having walls and within which said scanning electron microscope operates;  C) a linear motion feedthrough device that includes a linear motion feedthrough device shaft having a terminal end;  D) attached to the terminal end and within said operating chamber a tool;  E) in the vicinity of said tool and controlled via stage controls a manipulable platform;  F) a scanning electron microscope stage mounted on said stage platform; and  G) a testing/assembly stage mounted on said scanning electron microscope stage. 2. The micro testing and assembly device of  claim 1  wherein said linear motion feedthrough device is located within said operating chamber. claim 1 3. The micro testing and assembly device of  claim 1  wherein said tool is a microgripper. claim 1 4. The micro testing and assembly device of  claim 1  further including intermediate said scanning electron microscope stage and said testing stage a hot stage for controllably heating said assembly stage and any parts or materials located thereon. claim 1 5. The micro testing device of  claim 1  further including intermediate said tool and said terminal end, a load cell for the measurement of load applied to said tool during assembly or testing. claim 1 6. The micro testing and assembly device of  claim 1  further including an acoustic emission sensor for detecting contact between parts being assembled or tested. claim 1 7. The micro testing and assembly device of  claim 1  further including an alignment guide for said linear motion feedthrough device. claim 1 8. The micro testing and assembly device of  claim 1  further including a piezoelectric positioner located intermediate said linear motion feedthrough device shaft and said tool. claim 1
