Copper core PCB -- Hitech Circuits Copper core PCB is a copper substrate + Insulated layer + copper

Copper core PCB is a copper substrate + Insulated layer + copper circuits layer PCB,also, it is called copper substrate pcb, copper based pcb,copper clad pcb.
A copper base PCB is a metal core PCB with a copper substrate. If a hybrid PCB whose substrate is a copper plate inlay in the FR4 board, it is also a copper base PCB.
