No matter any electronic product, the specific components used depend entirely on the objective of circuit. Examining which components to work with is better dealt in the encyclopedia series. This leaves laminate boards and traces. Production costs, working efficiency and operating price of the finished circuit, all depend upon these components.
Of the several materials utilized for it's, six would be the most generally manufactured: FR-1, FR-2, FR-3, FR-4, CEM-1 and CEM-3. "FR" means "flame retardant". FR 1, 2 and three are critically the same, with only minor variations in properties. They are not suited for building multilayer boards. Does for CEM-1.
FR-4 and CEM-3 are a couple of laminates you can use for multilayer boards. Of these two, FR-4 is more widely manufactured, thus is cheaper. Quite a few for single and multilayer boards, and possesses excellent thermal tolerance around 130 .
