Board statistics

The Stats pane shows statistics for holes, routing, minimum features and other parameters. Parameters that can increase the cost of the product are highlighted with red text.

Minimum features

Minimum track width is the minimum width of electrical copper features on the layer. Minimum clearance is the minimum spacing between copper features on the layer. Minimum annular ring is the minimum ring width (pad radius minus hole radius) around plated holes on the layer.

Minimum track width and minimum annular ring are estimated by performing a simple analysis of the imported copper and drill layer data. Minimum clearance is estimated to be the same as the minimum track width. These estimates will be correct in most cases, but some CAD systems generate their trace and/or pad data in a manner that is too complex and timeconsuming for the rapid analysis performed by the Import module.

If you know that one or more of the estimated values are incorrect, you should enter the correct values as necessary.

Note: If an estimated value is zero, then you must enter a value.

Note: If you have specified a stackup with a copper thickness larger than 1 ounce (35μm) then you may encounter restrictions on the allowed minimum track width or clearance. The minimum allowed track width or clearance on a layer is typically 2 to 3 times the copper thickness.

Note: Minimum feature sizes are used during price calculation, and if incorrectly specified may lead to incorrect price quotations. They are checked by the seller's CAM department prior to production, and actual prices will be adjusted if necessary.

Mulit-board panels

If the product is a multi-board panel, specify the number of boards in the panel and the number of unique boards in the panel. Click on a hyperlink for more info about specifying board quantities.

Note: These values are used during price calculation, and if incorrectly specified may lead to incorrect price quotations. They are checked by the manufacturer's CAM department prior to production, and actual prices will be adjusted if necessary.
