Claim:
A method for repairing a test site on a test board in the testing of microelectronic devices, the method comprising: identifying a test site on the test board having a faulty permanent fuse and a plurality of socket components that protrude from the test site; providing a detachable replacement fuse, the detachable replacement fuse having a first lead, a first press-fit member at one end of the first lead, a second lead, a fuse element connected in series with the first and second leads, and a handle attached to the second lead with an opening in the handle; inserting the first press-fit member into a first lead hole in the test board such that the first press-fit member directly engages a plated section in the first lead hole and inserting the second lead into a second lead hole in the test board, wherein the first and second lead holes are electrically connected to the test site such that the detachable replacement fuse operates in the place of the faulty permanent fuse; testing at least one microelectronic component at the test site; and extracting the detachable replacement fuse from the test site by inserting a projection of an extraction tool between the socket components and into the opening in the handle, wherein the extraction tool comprises a guide surface that substantially matches an external surface of the socket components, and wherein the guide surface guides the extraction tool into place relative to the test board.
