This slide shows the small size TCXO manufacturing process. Steps one to twelve are the crystal assembly process, from quartz blank cleaning to taping. Step ten is the Final Test station which is the first 100% test process to confirm the 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 which is the second 100% test process, to confirm frequency over temperature compliance. Step eighteen is the third 100% test process, which confirms all TCXO specification compliance.
