Benefits of Modeling

Typical modifications resulting from electrical modeling result in:

• An optimized contactor interface to your
load board design
• Package Layout Simulation from Device to I/O
• Trace and pad characteristics
• Impedance matching
• Housing modification effects
• Contact design choice
• Ground inductance and plane changes
