JINHUA OEM Custom Black Immersion Tin Extra long pcb FR4 3L heavy copper circuirts board manufacturer

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.

FAQ

Q: Can a heavy copper PCB help reduce my product size?

A: Yes, Heavy Copper Boards can help reduce product size as it is possible to incorporate multiple copper weights on the same layer of circuity.

 

Q: What are the main advantages of a heavy copper PCB?

A: Increased current carrying capacity, increased endurance to thermal strain and increased mechanical strength at connector sites and in PTH holes.

 

Q: I need to put 55 Amps through my client. Can you advise on a Heavy Copper PCB design?

A: 55 Amps is not a problem. We can advise on all aspects of your Heavy Copper project.

 

Q: I need minimise package size, can I have a control section and a power section on a PCB?

A: By incorporating a multiple stage additive processing Heavy Copper boards allow for selected areas of a PCB to be plated to different copper weights. Typically used on the external layers of a PCB this process enables the control section and the power section to be on one panel reducing size and layer count.
