When a sample is especially heat sensitive there is the material “carbon
thread low power” available. The evaporation temperature is lower but with
increased pulse duration.
The method defines if the thread is pulsed or flashed (1). By ticking or un-ticking
the quartz usage box (2), it is defined how many pulses (or flashes) are done (3)
or if the process is finished by a thickness threshold (4). In case the thread was
mounted doubled to reach higher thickness, the double thread box must be ticked
(5).
Defining the sample height ensures that the working distance is kept constant.
The carbon thread source is angled 25° towards the stage. Tilting the stage
influences the coating angle. Rotation can be either set to continuous or a 120°
turn after each pulse (1). Settings can be checked by pushing the Test button. Init
stops the testing and moves the stage to the init position.
