A heatsink may be releasably secured to a substructure of an electronic system, such as a circuit board, in engagement with a heat-generating component, such as a processor. The system and process include uploading and reading a retrieved fault signature from a BIT log retrieved from a subject system under test. In the method of forming a metal interconnection, a recess region is formed in a portion of an insulation layer formed over a substrate, i. A connector is secured on a distal end of the piston. and a method for treating or preventing a proliferative disease, especially GIST, using such a combination. The wheel shim is preferably elongate and has a width sized to fit in the bead seat of the wheel rim, the thickness of the wheel shim being substantially less than the width of the wheel shim, and the length of the wheel shim being substantially greater than the width of the wheel shim.
