GESP TECH -TRUSTWORTHY ONE-STOP PCB SERVICES HEAVY COPPER PCB
Heavy Copper PCB is widely used in central power supply systems . and power electronic devices due to its ability to conduct larger currents in smaller product sizes. Generally, this unique type of heavy copper PCB features copper weight of more than 4oz (140um). compared to the 1oz (35um) or 2oz (75um) copper weight . generally found in those with a standard PCB copper thickness.Because the copper circuit board is thicker, it can carry a higher amount of current. get the heat to go where it needs to go and install complicated switches in small spaces. One more benefit is that the mechanical strength at the connection points is better.

BENEFITS OF HEAVY COPPER PCB
With the continuous development of technology. people need high performance, small size, multi-functional electronic products. to carry high current, reduce thermal strain. and heat dissipation of good electronic products are increasingly. Industries that benefit from thick copper PCBs are power supply. automotive, solar panel, and soldering equipment manufacturers. The copper plated vias of PCB thick copper boards are best suited for transferring heat to external heat sinks.
HEAVY COPPER PCB ADVANTAGES AS FOLLOW:
- Significant expansion of current capacity
- Greater tolerance for thermal strain
- More effective heat dissipation
- Enhanced mechanical strength at PTH holes and connectors
- Product size reduction
APPLICATION OF HEAVY COPPER PCB
The Auto Industry
Most thick copper PCBs are high-current substrates. and often used for electronic parts in cars. Traditional applications in the automotive, power. Now, thick copper PCBs used instead of transmission forms. This not only improves the speed of production. and cuts down on the cost of wiring, it also makes the final product more reliable.
High-current substrates that carry power devices and have high currents running through them. The main effect is to keep the power supply stable and protect the current carrying capacity. The copper foil on this high-current substrate is getting thicker. and thicker as it carries more current. because the heat from bigger devices needs to be removed. so the high current going through it is getting bigger .

HEAVY COPPER PCB FAQs
What is heavy copper PCB?
Heavy copper PCB is a printed circuit board with a copper thickness of 3 ounces per square foot.A standard PCB has 2 ounces of copper per square foot of thickness. An extreme copper PCB weighs 20oz to 200oz per square foot.
What is the function of the copper in the PCB?
Copper is an essential component of any PCB design . due to its exceptional electrical and thermal properties. which required for signal transmission and heat dissipation. Copper traces conduct heat as well as signals across the board.
