[03:40:49] <M6piz7wk[m]> the common experience of working with kicad files on github
[03:40:52] <M6piz7wk[m]> sigh

[06:11:10] <M6piz7wk[m]> looks nice doesn't it?
[09:36:29] <Tsvetan> M6piz7wk[m]: I saw your comment, do not understand me wrong, I like your enthusiasm as I said and I do not want to offend you, but do not suggest things you didn't test - re the aluminum base PCB, also the Teres PCBs all are with Gold 0.1" plating not HASL as in your document, this is not good.
[09:37:12] <Tsvetan> My advice still stands - produce and assemble one laptop then make PR, now you do it vice versa, we never publish anything we didn't test yet
[09:37:47] <Tsvetan> this is the reason iMX8Qmax and iMX8MPlus are not on GitHub, we didn't test the prototypes properly yet
[09:38:58] <Tsvetan> we publish only what we have tested and know it's right, to remove FR4 because some PCB manufacturer info is totally wrong, FR4 is industry standard for PCB base material, removing this info is not acceptable, suggesting aluminum base PCB without testing it is not acceptable
[09:43:17] <M6piz7wk[m]> > - re the aluminum base PCB
[09:43:17] <M6piz7wk[m]> I marked it as 'untested' for that reason since it's open-source and took reference values from a similar board, proposing to make a branch for it until the aluminium PCBs are tested then.
[09:43:17] <M6piz7wk[m]> > also the Teres PCBs all are with Gold 0.1" plating not HASL as in your document, this is not good.
[09:43:17] <M6piz7wk[m]> Noted will change that, can you please check the general notes in the proposed and clarify the fabrication?
[09:43:35] <M6piz7wk[m]> > this is the reason iMX8Qmax and iMX8MPlus are not on GitHub, we didn't test the prototypes properly yet
[09:43:35] <M6piz7wk[m]> Please give me those kicad files if you have them i would love to mess with them
[09:44:04] <M6piz7wk[m]> > to remove FR4 because some PCB manufacturer info is totally wrong
[09:44:04] <M6piz7wk[m]> Why?
[09:44:31] <M6piz7wk[m]> > FR4 is industry standard for PCB base material, removing this info is not acceptable
[09:44:31] <M6piz7wk[m]> it's removed from BOM because it's already mentioned in the technical drawing and general notes
[09:44:45] <M6piz7wk[m]> > suggesting aluminum base PCB without testing it is not acceptable
[09:44:46] <M6piz7wk[m]> fair
[09:47:53] <M6piz7wk[m]> > also the Teres PCBs all are with Gold 0.1
[09:47:54] <M6piz7wk[m]> Just to clarify `gold 0.1` is Electroless nickel immersion gold (ENIG) or ENEPIG (which adds a thin layer of electronless paladium over the nickel) ? or are you mean hard gold 0.1 ?
