Where do you place polygons in Altium Designer?

Where do you place polygons in Altium Designer?

Hatched polygon pours are commonly used for ground purposes in analog designs. Polygon Pours can only be placed in the PCB Editor. You can place them directly or create them from selected primitives. To place a polygon, switch to the required layer then perform one of the following: Choose Place » Polygon Pour from the main menus.

How are clearances and connection properties controlled in Altium?

Clearances and connection properties are controlled by the applicable Electrical Clearance and Polygon Connection Style design rules. Select the Place » Polygon Pour command from the main menus to place a polygon on the current layer in the PCB editor.

How are copper regions defined in Altium Designer?

Solid – When this mode is selected, the polygon is internally constructed from solid region objects, with a separate region for each contiguous area of copper in the completed polygon. This type of polygon is output to Gerber using Gerber region definitions.

Where to place a polygon pour in a PCB?

On a signal layer, you can place a solid polygon pour to define an area for carrying large power supply currents, or as a ground-connected area for providing electro-magnetic shielding. Hatched polygon pours are commonly used for ground purposes in analog designs. Polygon Pours can only be placed in the PCB Editor.

What are the different corners on Altium Designer 21?

Press Shift+Spacebar to cycle through the five available corner modes: 45 degree, 45 degree with arc, 90 degree, 90 degree with arc, and Any Angle. Press Spacebar to toggle between the two corner direction sub-modes.

Is it okay to use hatched polygons in rigid flex circuit?

Using solid copper pours is okay, as long as you don’t mind significantly reduced flexibility, and possible buckling of the copper under tight-radius bends. Generally it’s best to use hatched polygons to retain a high level of flexibility.

How to shrink the arc in Altium pour?

When in either of the arc corner modes, hold the , or . key to shrink or grow the arc. Hold the Shift key as you press to accelerate arc resizing.

How to place track segments in Altium Designer?

Track placement with Look-Ahead on (first image) and off (second image). The next mouse click will place the hatched track segments. The Look-Ahead feature also works during polygon pour placement. Press the 1 shortcut key during placement to toggle it on and off.

How do you delete a vertex in Altium?

To delete a vertex, click and hold on the vertex as if you were going to move it then press the Delete key. When you have finished, right-click then select Polygon Actions » Repour Selected to repour the polygon in its new shape.

What can a polygon pour be used for?

A Polygon Pour (brighter red) being used to create a large GND area on a board. A polygon pour is a group design object – that is, it is made up of simpler primitive objects. Polygon pours are used to create a solid or hatched (lattice) area on a PCB layer, using either Region objects, or a combination of Track and Arc objects.

How to define board shape in Altium Designer?

Run the Design » Board Shape » Define from selected objects command – the board shape will be redefined to the selected objects and the display updated. Open the View Configuration panel and double-click to edit the mechanical layer that holds the board shape.

How to revert to automatic naming in Altium?

If you have entered a custom name and wish to revert to automatic naming, simply clear the field and press Enter. Clearing custom naming and reverting to use automatic naming can also be performed from the PCB List panel and the Properties panel (with the polygon pour selected in the main design area).

What to do if a polygon is not connecting to a pad?

Try switching off the polygons (unpoured), then place a track from large GND pad to Net-Tie GND pad. Also from large AGND pad to AGND Net-Tie. Then try re-pour all, with “Pour over same net objects” enabled.

Do you need relief connect for polygon pour?

On the pads (which I will be soldering) I need to have a relief connect for the polygon pour of the same net, but I need a direct connection on the Vias of the same net. I currently have all Relief connects: But in the Design Rules I cannot find an option that would set Vias aside from component pads:

What are the different styles of Polygon connect?

Connect Style – defines the style of the connection from a pin of a component, targeted by the scope (Full Query) of the rule, to a polygon plane. The following three styles are available: Relief Connect – connect using a thermal relief connection. Direct Connect – connect using solid copper to the pin.
