Patent number: 11754617Abstract: It is an object of the present invention to provide a printed circuit board capable of accurately detecting disconnections of circuit patterns with an automatic circuit pattern inspecting device even when positions of mounting lands are slightly deviated from normal positions due to manufacturing errors. For solving this object, the printed circuit board of the present invention is provided with a first mounting land 4a and a second mounting land 4b, and a first circuit pattern 6a and a second circuit pattern 6b on a surface thereof, wherein a first electric checker land 10a and a second checker land 10b which are electrically connected with the first mounting land 4a and the second mounting land 4b are provided on a surface of a wiring board 2.Type: GrantFiled: January 24, 2020Date of Patent: September 12, 2023Assignee: TANAZAWA HAKKOSHA CO., LTD.Inventors: Keiichiro Yamamoto, Kazuo Tani, Masaharu Yano

Publication number: 20220369469Abstract: In a method of manufacturing a printed wiring board with a pattern formed using a printing process, a pattern of a portion requiring position accuracy can be accurately formed at a predetermined position. A method of manufacturing a printed wiring board 10 according to the present invention includes preparing a laminated board 12 including a metal layer 16 formed on a surface of a base material 14, forming a first etching resist layer 20a by printing a pattern of a portion 18a requiring position accuracy on the metal layer of the laminated board using a metal mask 32, forming a second etching resist layer 20b by printing a pattern of a portion 18b other than the portion requiring position accuracy on the metal layer of the laminated board using a screen plate 34, removing, by etching, the metal layer of the laminated board where the first etching resist layer and the second etching resist layer are not formed, and stripping the first etching resist layer and the second etching resist layer.Type: ApplicationFiled: January 21, 2020Publication date: November 17, 2022Applicant: TANAZAWA HAKKOSHA CO., LTD.Inventors: Keiichiro YAMAMOTO, Kazuo TANI, Masaharu YANO
