Process Flows

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).

For hybrid devices, Golden Altos can customize a flow to match your particular needs or use one of our standard flows which follow MIL-PRF-38534. Either way, we’re here to help engineer a solution for you.

Golden Altos offers several different process flows for monolithic and hybrid assembly
