ABSTRACT:
A test clip, or test adapter, is provided for connecting leads of a tester to terminals on a packaged integrated circuit. Spacers on the test clip, which act to precisely separate the contact pins, are formed separately using a stamping process. Spacers may be formed having a thickness which can be controlled to approximately one mil. Each of the individual spacers is sandwiched between two contact pins to provide precise spacing of the contact pins. A bar is inserted through a hole in each of the spacers and contact pins to form a linear array of contact pins and spacers. Two or four (as appropriate) of the linear arrays of contact pins/spacers are then mounted on a test clip body sized for a specific integrated circuit package. Each of the spacers may include an L-shaped extension which is urged under the integrated circuit package when the test clip is pressed onto the package so as to firmly secure the test clip to the package.
