I just had a thought.. if pcb's are made by exposeing them to UV light.
Followed etch bath. Could sunlight later on compromise the pcb .. ?
Do you mean the glasfibers epoxy substrate?
Most epoxy resins are not resistive against high UV radiation. But I can't
say anything about the epoxy used in FG4 PCB's.
I expect a soldermask will give a additional UV protection.
