Publication number: 20160081195Abstract: The present invention relates to a detach core substrate and a method of manufacturing a detach core substrate. In accordance with one embodiment of the present invention, there is proposed a detach core substrate that a conductive layer including a metal layer with an etching property different from copper is formed on a top surface and a bottom surface of an insulating layer formed thereon a surface roughness. At this time, the contact interface between the top surface and the bottom surface of the insulating layer is the detachment interface to be separated during the manufacture of the circuit board. In addition, a method of manufacturing the detach core substrate is proposed.Type: ApplicationFiled: September 11, 2015Publication date: March 17, 2016Applicant: Samsung Electro-Mechanics Co., Ltd.Inventors: Yong Yoon CHO, Ki Hwan KIM, Gun Woo KIM, Sung Won JEONG, Gi Ho HAN, Da Hee KIM
