Abstract

The present invention addresses the problem of providing an electrical inspection device capable of easily improving the efficiency of electrical inspection of a substrate to be inspected. The electrical inspection device according to one embodiment of the present invention is provided with: an electrical inspection head (11) having a plurality of probes (11a) capable of contacting a substrate (P)to be inspected from the normal direction of the substrate (P) to be inspected; a switching means (12) having a circuit capable of switching the connection to the plurality of probes (11a); and a bearing (13) that rotatably supports the electrical inspection head (11) and the switching unit (12) about an axis parallel to the normal to the substrate (P) to be inspected, the electrical inspection head (11) and the switching unit (12) being detachably connected directly in the normal direction of the substrate (P) to be inspected.

Description

technical field [0001] The present invention relates to an electrical inspection device and a holding unit. Background technique [0002] In manufacturing sites such as printed circuit boards, an electrical inspection device is used that inspects electrical characteristics of an inspection object substrate by bringing a plurality of probes (electrical contacts) into contact with measurement points on the inspection object substrate. [0003] As such an electrical inspection device, a device including an electrical inspection head having a plurality of probes and a switching unit having a circuit capable of switching connections to the plurality of probes is known. In this electrical inspection device, the electrical connection to the plurality of probes is switched by the switching means so as to correspond to the conductive pattern of the inspection object substrate, and the electrical characteristics of the inspection object substrate can be efficiently inspected. [0004...
