Thick Copper PCB Contract Manufacturing

You know that for PCB contract manufacturing, copper weight 1, 2, 3oz are the common options, which can carry most of the low power circuitries but cannot meet the high-power products’ needs, especially in power and automotive electronics. So that thick copper PCBs‘ demand increases rapidly, this type of boards possess copper weight from 4oz to 20oz (called extreme copper). Although the thicker ones are also possible but rare.

Q1: How long have you been making thick copper PCBs?

A: We start it from 1995.

Q2: How to get my project quoted?

A: Please contact us by Email or Live chat, you’ll get feedback in few minutes.

Q3: What if I have no a Gerber file?

A: Don’t worry and tell us your requirements or ideas, we can get it start from design.

Q4: What should be noted in making a thick copper PCB?

A: Note the ratio between copper weight and width of traces, 4oz requires 9mil more trace/spacing, 12mil for 6oz, 20mil for 12oz, etc.

Q5: What’s your acceptance standard?

A: IPC 2-3
