Patent Number: 
Section: abstract

A kit for preparing TEM sample holders includes at least one TEM coupon made of a sheet of material and having one or more paths from its edge to a TEM sample holder form embodied in the TEM coupon. There is at least one hole in the coupon defining the outer boundary of the TEM sample holder form. This hole has a mouth that defines a land of material. This land connects the TEM sample holder form to the edge of the sheet. The kit preferably includes at least one probe tip, where the probe tip has a probe-tip point, and finally, a press. The press has inner and outer dies and a former rod opposing the inner and outer dies. A shear punch is situated coaxially with the former rod. Thus, when an actuator drives the shear punch toward the inner and outer dies, the shear punch severs the land and cuts an opening in the TEM sample holder form, and simultaneously the former rod presses the probe tip point or points into the sheet of material. The result is a TEM sample holder with probe-tip points embedded in it, ready for inspection in a TEM of samples attached to the probe-tip points.
