odbpp

Just another ODB++ library

ODB++

ODB++ is a CAD-to-CAM data exchange format used in the PCB (Printed Circuit Board) industry for transferring design and manufacturing data. ODB++ (Open Database++) is a proprietary, but widely adopted, format owned by Siemens.

Goal 1

Extract basic part information such as location and component size. And the board outline.

• Component data is located in steps/{step_name}/layers/comp_+_top for the top side and steps/{step_name}/layers/comp_+_bot for the bottom side of the board.
• The board outline is defined in the step profile located at steps/{step_name}/profile.
• Generate a svg from this data, containg a board-outline layer and component layers (top and bot). The svg is setup in a way it's easy to view different layers, for example showing only the board outline, or a combination of board outline and top components. The bottom side should be rendered as it would be visible in real word, so the view should be mirrored left-to-right.

See proof of concept in /goal-1 concept/

Goal 2

General manufacturing and assembly metrics:

• Board size
• Number of layers
• Surface finish
• Minimum track space
• Minimum drill size
• Material and material thickness
• Copper layer thickness, inside and out
• Via's in pad

Goal 3

Render the full pcb stackup in svg and overlaying the part layers. The svg should be interactive so the user is able to see information about parts.
