Joining Different GNDs

There are times when you need to short or join different nets together at a designated common point in a design such as AGND and DGND. 

In Altium this can be accomplished using NetTies if you have control of the schematic.

If you don't have control of the schematic you will not be able to include a NetTie symbol and NetTie footprint in the design.

One option is to create a short circuit in the design and waive the DRC violation.

For example you could join two different nets using overlapping fills or solid regions.

Another option if you don't want to waive DRCs is to create a rule that allows for the shorted nets.  

To prevent holds and technical queries from your PCB fabricator include notes in the fabrication package that include shorted nets.

That's it !

Flex-Rigid Design Links

Here is an Altium article titled "Best Practice of Flex Circuit Design"

https://www.altium.com/rigid-flex-circuits-resources/best-practice-flex-circuit-design


It's a bit dated, it was published when AD16 was released, however it is still relevant and has some of the best graphics I have seen related to flex designs.

Flexible Circuit Technologies is a highly regarded Flex resource.

Wurth Elektronik's also has some good stuff to share about designing with Flex-Rigid.

Tips:


Define Rigid-Flex Regions using View > Board Planning Mode









Select View > Board Planning Mode, then Select > Design > Define Split Line 

Snapping Options (Try Track Lines and a little cheese)









To delete a splitting line wiggle the line then press the delete key.

Enable All Objects in the Selection Filter to grab Splitting lines.



Show all Single Layers and Enable Regions to Define Stackup Regions
