Normalmente, os PCBs de base de cobre têm a mesma estrutura que os PCBs de alumínio - camada única, camada dupla com lado de montagem de componente único, camada dupla com lados de montagem de componente duplo e quatro camadas com lados de montagem de componente duplo. Mesmo eles usam o mesmo material prepreg para isolar as camadas de cobre. No entanto, o substrato de cobre (398W/mK) tem melhor condutividade térmica do que o substrato de alumínio (237W/mK).
