Quartz control technologies for rate and end point termination.
Evatec's own new QCM 500 controller offers improved accuracy , faster switching time between crystals, 5 or 6MHz operation and multiple head management from a single controller. The QSK621 way quartz head is an ideal solution for many evaporation processes on the BAK platform. Full Khan integration handles crystal full or unexpected errors mid process with ease switching to back up crystals and ensuring batch evaporation processes can be completed without loss. For thicker layers and more complex processes a 12 way head is available for integration in new systems or for retrofit.
The QSK300 single head can be installed for single source monitoring in co-evaporation processes and both single and multiway heads can be fitted with chopper technology for control of extended layer thicknesses or longer crystal lifetimes
