Introduction
Advances in digital and analog technologies present new challenges PWB design Clock frequencies approach the L Band region
- Dielectric absorption, Skin Depth, Impedances, Dispersion - Power distribution, decupling - Noise immunity, stability
High Power and/or Lower Voltage High dynamic-range/low-noise analog circuitry High Density Components
- Xilinx FG1156 Fine Pitch BGA (1.0 mm pitch 39 mils) - Finer pitch BGAs 0.8 mm (31 mils) and 0.5 mm (20 mils) - Electrical, Mechanical, Manufacturing, Design/Drafting
