CUPRUM

The gerber viewer

built exclusively for Mac

Full gerber X2 support

Cuprum comes in two versions; a Community and a Pro edition

What’s new in Cuprum 4

Cuprum 4 can now show the net names of objects right on top of the object which allows a quick overview of which net runs where on the PCB.

A new aperture inspector enables full control of all properties of the aperture. If you just want to edit the aperture of a single object you can duplicate the aperture to avoid changing all other objects with the same aperture.

The new drill report shows a quick overview of the type and count of all drills.

Importing your company logo or a warning symbol is a breeze with the SVG image import option. 

Net names    

Show the net names right on top of the objects for super fast tracing.

Aperture inspector

Inspect and modify all aperture properties.

Drill report 

Quick overview of the type and count of drills in the project.

SVG import

Easily import your company logo or a warning symbol onto your PCB.

Features

Gerber X2, ODB++ and Excellon support

Cuprum is the first Gerber viewer for Mac with full Gerber X2 support, including verification of the MD5 checksum. Using the layer and object inspector all X2 attributes can be examined.

Besides Gerber X2 Cuprum can also import ODB++, Excellon and XNC. And when Cuprum detects a mismatch between the scale of your Excellon data and Gerber data, it wil try to make the Excellon data fit.

Highlight connected copper

The new highlight connected copper command allows you to select a copper object, and Cuprum will highlight all copper that’s connected to it.

This works across all layers and dimming intensity can be varied.

Compare images

Wondering what has changed between two revisions of a dataset?

The compare images function clearly shows the differences. The first two images on a layer are drawn either darker or lighter when there is a difference detected. Where the images are identical the normal layer color is displayed.

Quickly see which layer has changes using the differences count for each layer and jump right to a difference using a list of differences for each layer.

Drill report

The drill report shows a list of all drill types and their count. This is useful when preparing for production where the cost of the PCB is largely dictated by the count and size of the drills.

Import SVG images

Easily add your company logo or a warning sign to your PCB.

Using the SVG import option you can directly import SVG shapes into the document.

Of course, the shapes are exported to Gerber exactly as shown in the Cuprum document.

Inspectors

Various inspectors show the properties of the selected objects, apertures, layers, images and boards.

Most of these properties can also be modified.

Various tools are available for selection such as ‘Inside rectangle’, ‘Crossing line’ as well as ‘Connected Copper’.

Inspected objects can be filtered based on object type and layer.

From the object inspector, related objects can be selected, such as selecting all objects created with the same aperture. 

For Gerber X2 files, selection is also possible based on Component, Pin and Net information, if supplied by the file.

Net names

Net names, when imported from e.g. Gerber, ODB++ or IPC-D-356 files, will show directly on their objects.

Using the object inspector or nets navigator you can rename nets or assign new nets to objects.

Realistic rendering

Have a complex board to review? The realistic rendering mode will show you better how the finished bare board will look like.

Snapping

Advanced snap support with haptic feedback on Force Trackpads.

‘Object’ and ‘Boundary’ snap modes allow precise measurements when the distance to measure doesn’t start or end at an endpoint.

Gerber and Excellon export

Export the document as Gerber. If your board house has trouble handling drill data in the Gerber X2 format you can choose to export the drill data in the XNC format, which is Excellon compatible.

The advanced settings allows precise control over how the data is exported.

QuickLook

With the QuickLook plugin you can preview your files in Finder and other applications.

Transparent viewing

Find hidden copper features, such as via’s in copper regions.

You can choose to view everything transparent or only the regions (copper pours).

Additionally, you can select a single layer to always be transparent.

Single layer mode

Need to focus on a specific layer? In single layer mode you can dim other layers or turn them off completely, so the layer of interest stands out. 

Dimmed layers can be drawn in color, grayscale or monochrome (all the same shade of gray).
