Patent number: 10962569Abstract: Provided are a probe that enables control of a bending direction and can be simply manufactured, an inspection jig using the probe, an inspection device, and a method of manufacturing the probe. A probe has a substantially bar-like shape extending linearly and includes: a tip end portion, a body portion continuous with the tip end portion Pa; and a base end portion continuous with the body portion. The body portion includes a first connection region having a thickness in a thickness direction perpendicular to an axial direction of the bar-like shape that gradually decreases away from the tip end portion, and a second connection region having a thickness that gradually decreases away from the base end portion. A dimension of the body portion in a width direction perpendicular to the thickness direction is larger than dimensions of the tip end portion and the base end portion.Type: GrantFiled: May 16, 2019Date of Patent: March 30, 2021Assignees: Nidec-Read Corporation, SV Probe Technology Taiwan Co., Ltd.Inventors: Michio Kaida, Huei Che Yu

Patent number: 9910084Abstract: A flexible circuit board inspecting apparatus for conducting an inspection on a flexible circuit board includes a transport path and an inspection part mechanism. The transport path is configured to successively transport the flexible circuit board having a plurality of unit circuit boards arranged thereon. The inspection part mechanism is configured to bring and distance a jig for inspecting the flexible circuit board transported on the transport path close to and from the flexible circuit board. The transport path includes a longitudinal transport portion for transporting the flexible circuit board in a downward vertical direction. The inspection part mechanism moves the jig in a direction perpendicular to the flexible circuit board transported on the longitudinal transport portion to bring and distance the jig close to and from the flexible circuit board.Type: GrantFiled: March 19, 2015Date of Patent: March 6, 2018Assignee: NIDEC-READ CORPORATIONInventors: Takashi Nakagawa, Toshihide Matsukawa, Osamu Hikita, Michio Kaida

Patent number: 6462556Abstract: A probe is made to contact one end of the test wiring of a circuit board 32, with a head 52 electrostatically coupled to the other end of said wiring. A pulse-like DC voltage is supplied from a signal source 46, and, simultaneously with a switch section SWp turning on, the maximum voltage is applied to the test wiring. If a detection signal is below a specified value, then a computer 44 will read it as “open” or “shorting”. Further, a tip 52a of the head 52 is associated with the circuit board 32 only through an insulating sheet 33, so that the tip 52a is kept away from each pad of a pad section 38 on the board at a fixed distance (equivalent to the thickness of insulating sheet 33). Thus, continuity testing may be performed in a non-contact manner by moving head 52 only in X and Y directions without movement in the Z-direction.Type: GrantFiled: March 30, 2001Date of Patent: October 8, 2002Assignee: Nidec-Read CorporationInventors: Munehiro Yamashita, Michio Kaida
