Publication number: 20120125680Abstract: An opening is formed in resin 20 by a laser beam so that a via hole is formed. At this time, copper foil 22, the thickness of which is reduced (to 3 ?m) by performing etching to lower the thermal conductivity is used as a conformal mask. Therefore, an opening 20a can be formed in the resin 20 if the number of irradiation of pulse-shape laser beam is reduced. Therefore, occurrence of undercut of the resin 20 which forms an interlayer insulating resin layer can be prevented. Thus, the reliability of the connection of the via holes can be prevented. Thus, the reliability of the connection of the via holes can be improved.Type: ApplicationFiled: January 25, 2012Publication date: May 24, 2012Applicant: IBIDEN CO., LTDInventors: Naohiro Hirose, Kouta Noda, Hiroshi Segawa, Honjin En, Kiyotaka Tsukada, Naoto Ishida, Kouji Asano, Atsushi Shouda

Patent number: 7222776Abstract: A printed wiring board has a circuit substrate 6 having a conductor circuit 5 and a through hole 60, and also has a joining pin 1 inserted into the through hole. The joining pin is manufactured by using a material unmelted at a heating temperature in joining the joining pin to an opposite party pad 81. The joining pin is constructed by a joining head portion 11 having a greater diameter than an opening diameter of the through hole. The joining pin forms a joining portion for joining and connection to the opposite party pad. The joining pin has a leg portion 12 having a diameter smaller than the through hole. The leg portion is inserted into the through hole and is joined to the through hole by a conductive material such as a soldering material 20, etc. In lieu of a joining pin, a joining ball approximately having a spherical shape can be joined to the through hole by the conductive material.Type: GrantFiled: August 26, 2004Date of Patent: May 29, 2007Assignee: IBIDEN Co., Ltd.Inventors: Naoto Ishida, Kouji Asano
