Thermal Deposition- PVD

Thermal vacuum coating is one the simplest and oldest of the physical vapor deposition techniques. A solid sample of material is heated in a vacuum and the particles that evaporate travel though the chamber and condense on the substrate.
Thermal evaporation vacuum coating is most often used for depositing metal or metal oxide contacts on flat substrates. It is difficult to control the thickness of the deposit and surface irregularities may cause shadows. The temperature of the source determines the speed of the atoms as they hit the substrate thus making it possible to limit damage to the substrate. This is a relatively rapid technique suitable for roll to roll processing.

Cool video to get a practical idea of the PVD process. Thank you!

[@mayzin6790]

Useful video. Thank you so much.

[@monikah12345]

Very good video. Thank you.

[@user-zm7wf2fw8r]

Great video, thanks.

[@AngadSinghKushwaha9452288059]

fantastic lessons

[@georgeliu7575]

Great explanation of PVD

[@RuwanWij]

Does the material coat everything in the chamber? I'm assuming so, is there any way to focus deposition only on the substrate?

[@petsonly4068]

No. The receiving surface has opposite charge.

[@jackthessen1885]

how do you get the silver off of the boat when you are done?

[@aaronyang8931]

Helpful!

[@prianiw9637]

does material deposition especially carbon fiber on substrate take a certain time? what I mean is when the current is raised whether the material instantly evaporates or takes some time after the current is raised?

[@yvzgktrk495]

which thickness you reach with this method, and gokhan yildiz do you know something about the price ?

[@user-ul6bm8pt2y]

I'd just perform a Tollen's reagent like you do in 8th grade, that's cheaper :D
Great video.

[@porousorificePilot]

Is this process used in the manufacturing of old school TV CRT's?
peace

[@happycline]

where do you get these machines? (I doupt I can afford one.. but still...) very fascinating, and really helped me understand vapor deposition.. what is the boat made out of?

[@attackorange5314]

tungsten, molybdenum- any metal or substance that won't melt at high temperatures

why the shutter(shield) is needed?
