I see these PCB material types often: FR4 epoxy resin, FR4 epoxy glass. As I see, epoxy resin is cheaper than epoxy glass.
Is there a difference between epoxy resin and epoxy glass? Do they need different treatment on the manufacturing process? What are the main advantage or disadvantage to use epoxy resin?

The full name of FR4 is a flame-resistant glass-epoxy composite material. The "resin" is the epoxy prior to curing, and the "glass" is a matt of fiberglass strands that gives the composite strength. So what you asked are the same thing.

As I know, they are the same material. FR4 is a grade designation assigned to glass-reinforced epoxy laminate sheets, rods and PCB. FR-4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant
