Improving Fabrication Yields
How the CAM engineer can make the difference.
Embedded in fabrication planning is calculating panel size, checking layer stackup information, reviewing expected yields, reviewing board construction and verifying impedance control calculations.
Typical panel sizes are 9 x 12″, 12 x 18″, 18 x 24″, or 18 x 36″. A number of factors need to be considered when calculating panel size. For instance, consider a small board of 25 sq. in. A relatively high number of this small board can be panelized in an 18 x 24″ panel. But board complexity and density, or such factors as high-speed signals, trace thicknesses, or controlled impedance, could favor a 9 x 12″ panel.
