Abstract

The present invention provides a jig for substrate inspection and a related technique, which can reduce load in substrate inspection jig structure variation along with variation of an inspected substrate as an inspection object. The substrate inspection jig (2) is provided with the following components: a jig body (6), an electrode unit (7) and an inspection head (8). The electrode unit (7) is provided with a plurality of electrode heads which are approximately configured rectangularly and is replaceably mounted on a clamp body (6). The inspection head (8) is provided with a plurality of probes and probe keeping components and is replaceably mounted on the electrode unit (7) or the clamp body (6) so the back end of each probe electrically contacts with a random electrode head of the electrode unit (7). The electrode heads of the electrode unit (7) are approximately configured rectangularly through a mounting distance which is smaller than that of the probes of the inspection heads (8) so that the jig can correspond to a plurality of kinds of inspection heads (8) with different configuration modes on the probes.

Description

technical field [0001] The present invention relates to a substrate inspection jig mounted on a substrate inspection device and used in inspections related to electrical characteristics of wiring patterns provided on a substrate to be inspected, and related technologies. Background technique [0002] As a conventional substrate inspection jig, there is a substrate inspection jig in which the configuration of the electrode part provided on the electrode unit is a general-purpose configuration corresponding to various inspection heads with different probe arrangements, and can be used as the substrate inspection jig. The inspection head is replaced according to the configuration of the wiring pattern and the like of the inspected substrate to be inspected. [0003] Furthermore, in the substrate inspection apparatus using the above-mentioned conventional substrate inspection jig, a connection switching unit for switching the electrical connection relationship between the electr...
