Detailed Description

Manage layers needed to make a physical board.

They are solder mask, silk screen, copper and dielectric. Some other layers, used in fabrication, are not managed here because they are not used to make a physical board itself.

Note: There are a few other parameters related to the physical stackup like finish type, impedance control and a few others.

◆ GetLayerDistance()

int BOARD_STACKUP::GetLayerDistance	(	PCB_LAYER_ID	aFirstLayer,
		PCB_LAYER_ID	aSecondLayer
	)		const

Calculate the distance (height) between the two given copper layers.

This factors in the thickness of any dielectric and copper layers between the two given layers, and half the height of the given start and end layers. This half-height calculation allows this to be used for consistent length measurements when calculating net length through a series of vias. A more advanced algorithm would be possible once we have a good concept of the start and end for a length measurement, but for now this will do. See https://gitlab.com/kicad/code/kicad/-/issues/8384 for more background.

Parameters

aFirstLayer	is a copper layer
aSecondLayer	is a different copper layer

Returns: the height (in IU) between the two layers
