Testing method for leadless parts

Abstract

Abstract PURPOSE: To permit a leadless parts to be readily connected to a testing circuit by mounting a leadless parts on a printed board under pressure through an anisotropic conductive rubber plate. CONSTITUTION: A connector cable 6 fixed to the end of a flat cable 5 to be connected to a tester is detachably coupled with a connector jack 9 containing a terminals of a wiring pattern 8 for mounting parts printed on a printed circuit board 7. The other terminals 10 of the wiring pattern 8 are opposed to terminals 2 of the wiring pattern on the lower surface of a chip carrier IC1, which is a parts chip to be tested. Through a rubber plate 4, the parts 1 is mounted on the terminals 10, and the terminals 2 on the lower surface of the parts 1 are connected to the following tester. COPYRIGHT: (C)1981,JPO&Japio
