Patent number: 10083844Abstract: Provided is a method of manufacturing a bonded body having a structure where a substrate and an electronic part are bonded to each other with a metal particle paste interposed therebetween. The method includes an assembled body forming step where the electronic part is mounted on the substrate with the metal particle paste interposed therebetween, an assembled body arranging step of arranging the assembled body between two heating plates opposite to one another, and a bonding step of bonding the substrate and the electronic part to each other by heating while applying pressure to the assembled body by moving at least one of two heating plates to the other of two heating plates. The bonding step is performed under a condition that a temperature of the assembled body is within 0° C. to 150° C. In the bonding step, a metal particle paste minimally generates a sintering reaction.Type: GrantFiled: March 31, 2015Date of Patent: September 25, 2018Assignee: SHINDENGEN ELECTRIC MANUFACTURING CO., LTD.Inventors: Ryo Matsubayashi, Yuji Morinaga

Patent number: 9796052Abstract: The present invention addresses the problem of providing a composite nanometal paste which is relatively low in price and is excellent in terms of bonding characteristics, thermal conductivity, and electrical property. The present invention is a copper-filler-containing composite nanometal paste that contains composite nanometal particles each comprising a metal core and an organic coating layer formed thereon. The metal paste contains a copper filler and contains, as binders, first composite nanometal particles and second composite nanometal particles which differ from the first composite nanometal particles in the thermal decomposition temperature of the organic coating layer, wherein the mass proportion W1 of the organic coating layer in the first composite nanometal particles is in the range of 2-13 mass %, the mass proportion W2 of the organic coating layer in the second composite nanometal particles is in the range of 5-25 mass %, and these particles satisfy the relationships W1.Type: GrantFiled: March 30, 2012Date of Patent: October 24, 2017Assignees: APPLIED NANOPARTICLE LABORATORY CORPORATION, SHINDENGEN ELECTRIC MANUFACTURING CO., LTD.Inventors: Teruo Komatsu, Ryo Matsubayashi

Publication number: 20170069592Abstract: Provided is transferring members having a plate-like shape used in baking a metal particle paste of an assembled body formed by arranging an electronic part on a substrate with the metal particle paste interposed therebetween by applying pressure to the assembled body and by heating the assembled body, the transferring members being configured to sandwich the assembled body in baking the metal particle paste, wherein the transferring members are made of a material having thermal conductivity which falls within a range of from 1 to 200 W/(m k) and Vickers hardness which falls within a range of from 180 to 2300 kgf/mm2. With such a configuration, it is possible to provide a transferring member for being used in a method of manufacturing a bonded body which can suppress the lowering of bonding property between a substrate and an electronic part and which can prevent the remarkable lowering of productivity of a bonded body.Type: ApplicationFiled: March 31, 2015Publication date: March 9, 2017Inventor: Ryo MATSUBAYASHI
