Printed circuit boards (PCB) are usually coated with thick copper foil on a glass epoxy substrates commonly thickness of copper foil are 18μm, 35μm, 55μm, and 70μm. The most common copper foil is 35μm. The heavy copper PCB boards can simply be manufactured by two main processes plating and etching in the combine. As compared to other PCBs, the circuit is made of a thin layer of the Copper foil sheet. The plates of copper are laminated uniformly with FR4 or other epoxy-based substance. The average weight of the thick copper PCB weight could be 4oz (140μm), and this ratio is better as compared to another type of PCBs who have copper in common. Let’s check out the b...

Heavy Copper PCB Board
Benefits of Heavy copper PCB Fabrication
Here are some of the advantages of heavy copper PCB, let’s follow them:
1. Favorable circumstances Of Heavy Copper PCB
2. Plating innovation in overwhelming copper permitted a mix of plating and carving which causes in straight sidewalls and immaterial undercut.
3. The substantial copper plating creates high-current circuits and control circuits that watches the profoundly thick and straightforward whiskers’ structure.
4. This empowers the board fabricator to build the measure of copper thickness in plated gaps and by means of sidewalls.
5. The blend of substantial copper results on a solitary board called PowerLink.
6. The substantial copper in the PCB likewise encourages in associating with the standard circuits.
7. This lessens layer tally, low impedance control conveyance, littler impressions, and potential cost investment funds.
8. For development purposes, it expands the continuance to warm strains.
9. It has expanded the current conveying limit.
10. Overwhelming copper plating brings higher current through the board and moves the warmth to the outside heat sink
What is Heavy Copper PCB?
Heavy copper PCB is a circuit board with a copper thickness that is ≥ 3oz per sq. ft in its outer and inner layers. What makes a circuit board classified as a heavy copper PCB is its thicker plating. During the production of heavy copper PCB, copper thickness is enhanced through plated holes and sidewalls. For instance, when a PCB has 2 ounces of copper per sq. ft thickness, it is a standard PCB. However, if it has more than 3oz of copper, it is a heavy copper PCB. Heavy copper PCB is considered a reliable wiring option. Heavy copper PCB is different from extreme copper PCB which features within 20 oz to 200 oz per sq. ft.
