Buellton Advanced Materials PVD Coatings
Electron Beam
Our chambers have multi-hearth sources allowing for multiple materials to be deposited without having to break vacuum to atmosphere and to be applied in one continuous process. Specialized chambers allow 360 degree coating coverage, also equipment setup with specialized tooling to allow for coating of two sided substrates without breaking vacuum. BAM's larger coaters are setup with 5 and 6 electron beam guns respectively for large area highly uniform coating coverage.
Thermal Evaporation
Utilizing a resistance heater to melt the material and raise its vapor pressure to a useful range. Useful for materials that may disassociate using electron beam deposition - such as ZnS, YF3.
Sputter
Our sputter tools are configured to deposit up to three material types per coating run without breaking vacuum, providing the best quality of film stack. BAM has a dedicated Indium Tin-Oxide tool that can deposit highly optically transparent ITO onto plastic as low as 15 ohm's/square and at near ambient temperatures, allowing us to apply this type of film without distorting or damaging the plastic.
