Understanding 2OZ Copper Thickness: IPC Standard vs. Real-World Practice

When customers request a “2OZ copper thickness” for their PCBs, it seems like a straightforward specification. After all, 2OZ copper equates to 70μm in theory. But here's where it gets tricky—once the PCB Manufacturer is manufactured and cross-sectioned, the measured copper thickness often shows just around 60μm, sometimes even lower. This discrepancy frequently causes misunderstandings a...
