Fully Automated Atomic Layer Depositioning (ALD)
The race for finding alternative energy sources and reducing our carbon foot print is becoming more and more important to the survival of our life on Earth. Because we are more dependent on energy to power our lifestyles than Earth's resources allow, research facilities around the world are frantically trying to come up with new ways to meet our earthly demands without destroying our planet. One such organisation here in Australia is doing just that by researching better ways to harness the suns energy through photovoltaic technology. By opting to use Atomic Layer Deposition (ALD) for their thin film coating process they are coming up with more efficient solar cells which harness more of the suns energy and in turn yield better power outputs with the same size solar panel.
Initial research using ALD precursors gases were controlled manually and they could not reach their desired results. The precursor valves could not fire fast enough to get the right thin film deposition onto the substrate and the only way they could achieve the desired result was to find a way to control the valves at the fastest rate possible. AVT Services Pty Ltd was called in to find a solution to this problem. AVT designed a fully automated control system with simple, user friendly controls for three precursor gases using 30 millisecond control valves and three mass flow controllers with unlimited valve control combinations and recipes. The system controls all relays and contactors for the vacuum equipment from the roughing pump, turbo controller and associated valves. The substrating heating is also controlled by the system making sure that the chamber is at its optimum temperature for an ideal deposition. All data is logged from MFC flows, vacuum and temperature readings are viewable during and after each process. This gives a detailed picture of the results where users can either use it for fine tuning or displaying an optimal procedure for deposition. With this new tool at their disposal, we are one step closer to winning the free clean energy race that our future depends on.

The Edwards XDS Dry Scroll Pump
The Edwards scroll pumps are the only truly dry scroll pumps on the market today. Because they are completely dry running pumps, they require no messy oil changes or oil dumps.
Innovatively, Edwards have designed the XDS series to use a single pair of scrolls, allowing quick and easy user maintenance, thus reducing costs and precious down-time on service and repair.
Due to their dry mechanism, XDS pumps have become the pump of choice for clean/dry pumping, wet chemistry, LCMS, oxygen pumping, and many other lab and non-lab applications.
The competitor for and against chart below speaks for itself in regards to the superiority of the XDS pumps to other scroll pumps currently on the market.
Contact AVT Services for more information.
AVT's repairs workshop hits the 21st century
last year, AVT upgraded their workshop testing systems to include new software to allow a broader range of tests to be conducted on your vacuum equipment to ensure a better repair.
Our initial service outline includes pre-testing, disassembly and rigorous assessment of your equipment before sending you a full service report including damages to the pump, parts needed to repair and total cost of the repair. Once this meets your approval, we then reassemble your pump and put it under our new state of the art testing area to make sure that your pump meets optimal operational standards in every way possible.
