Publication number: 20150059162Abstract: First and second measurement probes come into contact with first and second electrode pads, respectively, and third and fourth measurement probes come into contact with the first and second electrode pads, respectively. A current flows in a current path including the first and second electrode pads and a plurality of lines through the first and second measurement probes. A value of the current in the current path is measured, and a value of a voltage between the third and fourth measurement probes is measured. Conductivity between the first and second electrode pads is inspected based on the measured value of the current and the measured value of the voltage.Type: ApplicationFiled: September 4, 2014Publication date: March 5, 2015Inventors: Terukazu IHARA, Kouji ICHINOSE

Publication number: 20140345920Abstract: Heat-assisted wiring traces and a conductive support substrate are respectively formed on first and second surfaces of an insulating layer. Further, connection terminals electrically insulated from the support substrate and electrically respectively connected to the heat-assisted wiring traces are formed on the second surface of the insulating layer. Each connection terminal has an element connection portion, a pattern connection portion and a spread blocking portion. When a circuit element is connected to the element connection portion of the connection terminal by solder, spreading of a molten solder applied to the element connection portion to the pattern connection portion is blocked by the spread blocking portion.Type: ApplicationFiled: May 9, 2014Publication date: November 27, 2014Applicant: Nitto Denko CorporationInventors: Terukazu IHARA, Naohiro TERADA
