Heavy Copper PCB (Printed Circuit Board) is manufactured by using combination of copper etching and plating processes. The circuits used in the process are layered as thin sheets of copper foil. These circuits are then etched to remove unwanted copper, next it is plated to add copper thickness to planes, traces, pads and plated-through-holes. These circuit layers are laminated using an epoxy-based substrate, such as FR4 or polyimide.

Various Advantages Of Heavy Copper PCB:

1. This specializes in etching and plating techniques.
2. Plating technology in heavy copper allowed a combination of plating and etching which causes in straight sidewalls and negligible undercut.
3. This enables the board fabricator to increase the amount of copper thickness in plated holes and via sidewalls.
4. This reduces layer count, low impedance power distribution, smaller footprints and potential cost savings.
5. The mix of heavy copper results on a single board called PowerLink.
6. The heavy copper in the PCB also helps in connecting to the standard circuits.
7. The heavy copper plating generates high-current circuits and control circuits that observes the highly dense and simple beard structure.
8. For construction purposes, it increases the endurance to thermal strains.
9. Heavy copper plating carries higher current through the board and helps to transfer heat to external heatsink.
10. It has increased current carrying capacity.

Industries which uses heavy copper circuit boards:
a. Welding Equipment
b. Power Supplies
c. olar Panel Manufacturers
d. Automotive
e. Power Converters

People mostly are using heavy copper PCB and extreme copper PCB designs for maximum reliability. This can be used with exotic materials without any circuit failure. Since there has been a growing trend in the number of power electronics products, PCB (Printed Circuit Board) industry is focusing in the advantages of heavy copper.
