To create breakaway-tab panelization, define a route tool path slot around the edge of each board, leaving small sections of remaining board that are perforated by a series of small holes, as shown in the adjacent image. V-groove panelization is inexpensive and effective for rectangular shaped boards non-rectangular boards must use breakaway tabs. There are two common approaches: V-groove panelization or breakaway-tab panelization. Since the Embedded Board Array links to the source PCB, any design changes made in the source PCB are loaded into the Embedded Board Array the next time the array board file is opened.Ī key part of the panelization process is defining how the individual boards are to be separated. The layer stack, dimensioning, V-groove, and route information has been added in this file rather than in the original source PCB. This was created by placing two Embedded Board Arrays one with the boards facing up and the other with the boards flipped. The image below shows a board repeated eight times in a step and turn pattern (alternate boards flipped). By placing multiple Embedded Board Arrays, you also can create a fabrication panel of different boards, or the same board can be laid out in a step and turn pattern.
The Embedded Board Array stamps out the linked board from 1 to n times at the specified spacing.
The panel can be defined by the fabricator, or alternatively, the board designer can create a panel in the PCB editor, using a feature referred to as an Embedded Board Array, also known as panelization.Īn Embedded Board Array is a primitive design object that you place into the PCB design space and link to an existing board file. Verification of Layer Stack CompatibilityĪ printed circuit board is not fabricated as a single entity typically a number of boards are fabricated on a panel.
