Power Module Advantages
- Improved Performance - discrete components are tested at full current / power ratings and can be selected for matched performance prior to PM assembly
- Improved Reliability - uses prescreened & qualified components and thermally matched materials to maximize power evacuation while minimizing thermal stress
- Higher Working Currents and Lower Conduction Losses– replaces wire bonds with heavy gauge, high current handling heatsunk copper traces
- Weight Reduction – uses lightweight materials
- Simplified Next Level Assembly – terminations optimally located to interface with the system
- Any Size or Shape – takes full advantage of available system real estate, including 3D capability
- Any Terminal Type– high power threaded, soldered male/female turrets, flex cable, power bar, etc; mix & match different control and power connections
- Repairable / Reworkable
