FC-BGA Substrates (GigaModule)
GigaModule-1,2 -2E
- High-density wiring structure, applying Build-up and solid-via plating technology.
- For High pin-count & High performance substrates, such as MPU, ASIC and Graphic controller for network systems and high-end servers.
GigaModule-4 (Full build-up)
Ultra high density wiring structure
- FICT enables to provide Ultra-Thin & High-density wiring structure, applying core layer free, full build-up, and full stacked-via technology.
- Reduce layer count by half of conventional technology.
- For next generation high-end substrate and ultra-thin module.
- Low inductance property enables GHz bandwidth operation with lower transmission loss.
