Publication number: 20170295651Abstract: An electronic circuit board manufacturing method according to the present disclosure is a method of manufacturing an electronic circuit board including a substrate and an electronic circuit having a predetermined pattern, the electronic circuit being fixed on the substrate and being made from a nanoink composition containing metal particles. The method includes the steps of: causing a printing plate to hold a nanoink composition containing metal particles, the printing plate including an ink holding part formed on a surface thereof and having a predetermined pattern; bringing a surface of the substrate into intimate contact with the printing plate to transfer the nanoink composition held on the ink holding part onto the substrate; and drying the transferred nanoink composition in an environment of 40° C. or below in the atmosphere to fix the nanoink composition after the transfer step, thereby forming an electronic circuit having a predetermined pattern.Type: ApplicationFiled: August 31, 2015Publication date: October 12, 2017Applicant: KOMURA-TECH CO., LTD.Inventors: Masayuki Kanehara, Masaaki Urano
