What is Difference between PCB and PCBA ?

Printed Circuit Board is the most expensive one in the metal core PCB.Thermal conductivity is better than aluminum based PCB. Copper core PCB is suitable for high-frequency circuits, as well as an area with great temperature difference and heat radiation of precision communications equipment and architectural industry. Copper-based PCB circuit requires a great deal of current-carrying capacity, which should be used with a thick copper foil, the thickness is usually 35μm~280μm. A thermal insulation layer, which has small heat resistance, excellent viscosity property, and ability of mechanical and thermal stress, is the core technology of the copper-based PCB.

The copper-based metal board is copper clad PCB supporting member, requiring high thermal conductivity, usually copper, and you can also use copper (copper board provides better thermal conductivity), which is suitable for conventional mechanical processing such as drilling, punching, and cutting.

Advantages of Copper Clad PCB:

1.Environmental Friendly: due to copper-based PCB doesn’t include a metal material, it won’t pollute the environment.
2.heat radiation: Copper has excellent heat radiation, which makes the copper core printed circuit board to be more stable.
3.Lightweight: It has no occasion to install the radiator.The volume is greatly reduced, and the machinability of the products is greatly improved.
