HI,
I just wonder what kind of components can I use on FR1 board? can I use Microcontroller on FR1?
I have one remote board and wanted to put all my numbers on FR1 is it possible?
Thanks,
 

Hi,

FR1，phenolic cellulose paper copper-clad laminates(phenolic/paper CCL)，this kind of board couldn't be plated, the surface finish couldn't be HASL, endure 105 degree.

FR4，epoxide woven glass fabric copper-clad laminates. It's a common base board to double side & multi side.
