3) Symmetric layer buildup Ensure a uniform distribution of the 3 components: prepreg, core, and copper foil Advantages:
Less bowing, twisting, or deformation Reduced costs Improved…
2) Identical copper thickness on the cores Always plan the cores with identical copper cladding. Advantages:
Less bowing, twisting, or deformation Symmetric design Reduced under…
1) Keep the number of prepregs low Use at most 2 prepregs per layer (also recommended by IPC). Exceptions with only 1 prepreg: Many layers in a multilayer with defined total thickness, use of…
