You have to know the common sense of PCB base material.
There were many PCB base material use of different PCB manufacturer.
This post will discuss the PCB base material use by China aluminum PCB manufacturers.
There are 6 major different materials, FR-1 FR-2, FR-3, FR-4, CEM-1, CEM-3 (except Isola FR406N, Rogers, Aluminum), used to make metal core PCBs.
We have shared several articles to discuss the PCB base material,
The FR-4 PCB base material is the best selection to manufacture PCB
Some materials may be cheaper, but it can only be used to make simple boards, and the reliability of the boards made by these materials is not good.
