Process Flows
Explore our process flows for monolithic and hybrid assembly
For monolithic devices, Golden Altos has five assembly process flows to handle requirements from “quick turn” engineering samples all the way through space level MIL-PRF-38535 (Class S).
We’re here to help engineer a solution for you.
