wish list：Pcb calculator track width standard update to IPC-2152

[Liu Guang]

IPC-2221 is outdated and hopes to update to IPC-2152

To give an overview over the changes:

The table of content:
http://www.ipc.org/TOC/IPC-2152.pdf

I could not find the standard in full text, is there a way to view it?
I am interested in changing it, as it would be a easy first fix to get to know the workflow and tooling for KiCad development.

OK,I will upload the IPC-2152-2009 standard tomorrow.

[Seth Hillbrand (sethh)]

Please do not upload IPC documents to the bug tracker.

Is there a copyright risk?

[Wayne Stambaugh (stambaughw)]

AFAIK, IPC standards are copyrighted material and cannot be freely
distributed so please do not post them on any KiCad website.

OK

Just to comment on this. Typically the IPC-2221 is more conservative than IPC-2152 but that isn't always the case nor is it right.
SaturnPCB includes IPC-2152 with/without modifiers BUT how it does it or validation is not included.

Below is a good online calc I found some time ago and the javascript can be accessed to validate the implementation. I did want to start submitting code to incorporate this but my CPP is extremely rusty, let alone being unfamiliar with the codebase
