Aug 22, 2026, 11:14 PM@dlharmon is this much extra IL in line with what you'd expect on oshpark from plating and copper roughness?

Darrell Harmondlharmon@chaos.socialAug 23, 2026, 3:07 AM@azonenberg Yes, about in line with what I'd expected. Copper loss is probably dominant in OSHPark 4L due to the very rough ED copper, relatively thin dielectric.
If you want to send me one to capture better data, I'd be happy to measure.

@dlharmon i do want you to measure but not until a few other things i have in the pipe finish so i can measure everything together
