Step ten is the Final Test station which is the first 100% test process, to confirm crystal specification compliance. Steps thirteen through twenty are the TCXO assembly process, a total of eight stations from IC stub bump to taping. Step seventeen is the TC Verification station, the second 100% test process, used to confirm frequency over temperature compliance.
