ALTIUM 4 layers stackup

Good day, im porting some settings about the specs of the 4 layer stack up in altium, need more info coz i must calculate an impendance for an RF strip line.
Suggestions and corrections are well appreciated

The layer thickness and copper weight are not correct yet, the Er value also needs to be adjusted. We have these documented in our 4 Layer article. Please note that you need to use the final dimensions.

Okay… do you mind suggest me pls the correct values? or check pls the new adjustemt

Please follow these settings

thank you for your info… the size refered in millimeters can be ported also for altium stackup setup?
Waiting for a kind response
Regards
David

How do you mean this? You can enter the values in Altium the copper thickness is 0.035mm → 35µm → 1 OZ

okay thank you for your informations… i will check it later

please send me link for Altium 4 layer stackup

Good day, I’ve found in this rep some info about aisler

it’s only published the altium 6 layers stsckup… miss the 4 layer stackup and i don’t remember well if aisler pcb stackup parameters are correct

Hi Thea,

This differs from your post https://community.aisler.net/uploads/default/original/1X/7697769deec9bcacbd18ab5e83a5315bcc8ab70b.jpeg

F.Cu and B.Cu 0.035 != 0.018

Which is right now?

Hi,

As mentioned above, the Github templates say the outer copper layers are 35um thick, but the stackup diagram says 18um.

I’m assuming the template is just a typo and the stackup is actually 18um thick on the outer layers?

Thanks

You have to look at the processed thickness in the diagram. The base copper foil is 18 µm and after plating it’s at least 35µm.
