Copper core PCB is different from the standard metal core PCB
A new test of copper core PCB
There were many tests during the PCB manufacturing process, but if you visit a copper core PCB factory, you many see some difference testing.
Into a 4,2mm thick stack-up we have implemented two 1,8mm solid-copper-cores with additional heat-sink-blind-vies.
In between, complex signal layers are running just like on a standard 4-layer multilayer PCB.
The design of copper core PCB heat management
You know metal core PCB has good heat management performance.
During copper core PCB design process, you should consider more factors than MCPCB design.
This is a combination of a complex multilayer layout and high-performance heat-management.
