How do you remove unused pads in Altium?

How do you remove unused pads in Altium?

To help reduce their impact on copper areas, Altium Designer includes an Unused Pad Shapes removal tool. The tool scans all pads or vias in the design and removes the pad shape from each layer for which the pad or via is not used (meaning it has no other objects touching it on that layer).

Where are the pad properties in Altium Designer 21?

Select the object in the Primitive List to reveal its options on the right. Post-placement settings – all Pad object properties are available for editing in the Pad dialog and the Properties panel when a placed Pad is selected in the design space.

Is there a way to remove unused pads?

The tool scans all pads or vias in the design and removes the pad shape from each layer for which the pad or via is not used (meaning it has no other objects touching it on that layer). Polygons that surround that pad or via then only need to create the specified clearance to the pad or via hole instead of to the edge of the unused pad shape.

How do you make a shape in Altium?

Placed Line/Arc objects in the desired shape. Placed an Arc using the Heads Up display to set the radius and the horizontal Lines to snap the start and end points. Selected the Lines and Arcs then ran the Tools » Convert » Create Region from Selected Primitives command.

How do you move a via in Altium?

Vias cannot have their properties modified graphically other than their location. To move a via and also move the connected tracks, click and hold then move the via. The connected routing will remain attached to the via as it is moved.

Where are via definitions stored in Altium Designer 21?

Via definitions can also be stored in Pad and Via Template libraries, refer to the Pad & Via Templates and Libraries page to learn more. Vias are available for placement in both the PCB editor and the PCB Library editors in the following ways: Click Place » Via from the main menus. Click the button on the Wiring toolbar.

Why do you need to fill a buried µvia?

Buried µVias are required to be filled, while blind µVias on the external layers do not require filling. Stacked µVias are usually filled with electroplated copper to make electrical interconnections between the multiple HDI layers and provide structural support for the outer level (s) of the µVia.

How are design rules created in Altium Designer 21?

The latter, in combination with rule-scoping, provides the flexibility to build a concise and targeted set of clearance rules to meet even the most stringent of clearance needs. All design rules are created and managed within the PCB Rules and Constraints Editor dialog.

When to use same net only clearance in Altium?

Use this constraint to configure the clearance when the nets in the differential pair must be closer together than allowed by the general clearance. For a defined Same-Net Only Clearance rule, the general approach is that if two objects are touching (i.e. connected), then they are not deemed to be in violation of the rule.

Can you put vias under surface mount components?

Allow Vias under SMD Pads – specifies whether vias can be placed under the pads of surface mount components. All rules are resolved by the priority setting. The system goes through the rules from highest to lowest priority and picks the first one whose scope expression matches the object (s) being checked.

How to disable clearance check in Altium Designer?

You can specify a design rule for that component: Then Altium Designer will not check this component’s clearance.

When to use lowercase and star in Altium?

The lowercase and star after the component are in place in case you have multiple components who have collisions like: usb_1, usb_2 and usb_3 Make sure that the priority of this rule is higher than other rules, who might be conflicting with this one.

How to disable clearance check for a layer or.?

Then Altium Designer will not check this component’s clearance. This isn’t necessarily an answer on how to do this specifically in Altium, but more of a generic thought: why not simply specify the outline of the heatsink so you can see it in the board layout view, and know it’s there, but not have it be something that is used in a clearance check?
