PCB = printed circuit board and PCBA = printed circuit board assembly. For PCB, it means the copper circuits be printed on a board, and so the main composition are copper and board.
The copper is the circuits material and the circuits designed by the PCB designers. Depends on the current in the circuits, the PCB copper thickness could be done with 0.5oz-10oz. But the PCB designers need be noted that the copper track width/space need be enlarged with the thickness. For example, the minimum copper track width/space could be 3mil/3mil with 0.5oz, but would be 4mil/4mil with 1oz.
The PCB board could be rigid PCB, could be flex PCB and also could be Flex-Rigid PCB. And the materials could be FR4, PI, Aluminum, Copper-based, Rogers, Teflon, etc. They have different applications. For example, FR4 PCB is the most commonly used for rigid PCB and almost good for all electronics products; PI is the most commonly used for flex PCB; Aluminum and copper-based have good thermal diffusivity and always used for LED PCB ; Rogers PCB and Teflon PCB are always used for High Frequency PCB, etc.
We are the one-stop shop for all kinds of PCB manufacture service from PCB Prototype to big volume, which could save our customers a lot of time and money.
