Extended use of 'Flipped On Layer' Property

Old Content - visit altium.com/documentation

Altium Designer 14 saw the arrival of support for embedded discrete components. Embedding discrete components directly under an integrated circuit can result in: shorter signal lengths; reduced resistance and parasitic inductance, leading to lower noise and EMI; and improved integrity of the circuit signals. These improvements deliver smaller and more reliable products, supporting faster signal speeds and higher bandwidths. Combined with the on-going improvements being achieved in fabrication processes and technologies, they can also lead to a reduction in the product size, and lower fabrication and board level assembly costs.

For detailed information on Altium Designer's support for embedded components, see Designing with Embedded Components – one of a set of articles dealing with High Speed PCB Design.

Examples of embedded components.

When embedding a discrete component within an internal copper layer of a circuit board, the direction that the embedded component orients (up or down) is defined by the Orientation specified for that copper layer in the Layer Stack Manager dialog. If needed this can be overridden at the individual component level, by enabling the Flipped on Layer option in the Component properties dialog. Until now, this has been the only place to access this property, which is not so bad for a handful of embedded components, but soon becomes a laborious task as that number increases.

Component orientation is determined at the layer-level through the Layer Stack Manager, but can be overriden at the individual component-level using the Flipped on Layer property.

Extended Support - Inspector, List & FSO

In Altium Designer 14.3, access to this property has been extended. You can now find the Flipped On Layer property through the PCB Inspector panel, PCB List panel, and Find Similar Objects dialog.

Access the Flipped On Layer property from the Inspector and List panels, as well as the FSO dialog.

Query Language Support

Extending use of the Flipped On Layer property to the Query Language, the Boolean ComponentFlippedOnLayer keyword has been added for use in logical filter queries.

Use the ComponentFlippedOnLayer keyword in expressions (or scripts).

This keyword returns all components whose Flipped On Layer property complies with the Query. Examples are:

  1. IsComponent And ComponentFlippedOnLayer

Returns all components that have a True Flipped On Layer property.

  1. IsComponent And ComponentFlippedOnLayer = True

Returns all components that have a True Flipped On Layer property.

  1. IsComponent And Not ComponentFlippedOnLayer

Returns all components except components that have a True Flipped On Layer property.

  1. IsComponent And ComponentFlippedOnLayer = False

Returns all components except components that have a True Flipped On Layer property.

Scripting Support

Extending use of the Flipped On Layer property to the scripting domain, the Boolean FlippedOnLayer property has been added to the Component interface (IPCB_Component.FlippedOnLayer).

Use of the FlippedOnLayer property in a script.
