Old is New Again

The R&D team at Plasma Process Group has transformed two older sources and upgraded them for your benefit. This summer we will be releasing our versions of a 6cm and versatile 6×22/30cm RF ion beam sources.

The 6cm RF source will allow users to gain the advantages of ion beam in much smaller spaces. With a diameter of 7.5″ and a depth of about 5.5″, the new 6cm RF source will fit into chambers where our larger 12cm and 16cm RF sources will not. Despite its relatively small size, the 6cm source will offer a significant increase in beam current over the 3cm DC source.


Designed specifically to be adaptable, the new 6×22/30cm RF linear ion source will allow users to select which grid size is most appropriate to their process. The larger size (6×30) increases the beam current and runs with flat graphite grids in a variety of patterns. The smaller size (6×22) offers shaped Molybdenum grids, which can provide the needed beam control for critical processes. Additionally, all feedthroughs exit the side (not the rear) of the ion source, which makes positioning the source much more flexible. This source is the perfect addition to a web or roll coating system…

Powering your Process

It’s been mentioned before, and you can be sure we’ll mention it again – Plasma Process Group has the replacement for your old, dying power supplies. If you’re curious but you don’t want to commit without seeing for yourself how well our supplies work, ask about our Demo unit! We’d be happy to let you use our power supply for a week or two to prove just how easy the transition will be!

That’s right, you can try before you buy! If that’s not cliche enough, how about this? We’re taking it to the next level by returning to our core competencies and thinking outside the box – and that’s how we came up with a smaller box! Our I-Beam all-in-one power supplies combine the entire power supply cluster into a single unit, simplifying connections and user interface. Further, if anything goes wrong with your new I-Beam power supply, we’ll send our loaner unit to you so you’re not system-down during repairs!

We have an App for that…

Our Applications Lab can help you do research and development on a dual-ion-beam deposition system without slowing down your production! If you don’t have any ion beam systems, our in house Techne system can help you decide if ion beam deposition is a smart move for your company, without having to invest more than a few days and a few dollars! Bring us your process, parts and engineers, and we’ll let you use our fully-equipped, fully-automated in-house system to test for yourself!

Have a new process idea, but you’re not quite sure how to do it? Let our engineers help figure it out! The Applications Lab at Plasma Process Group is your ticket to becoming the market leader in a whole new product line.

Proper care for your Ion Source Grids

Even though we offer grid cleaning services, many customers choose to do their own ion source grid maintenance. With proper attention to detail, keeping your grids in good working order is not too difficult. There are a couple important things to keep in mind. As with any high-tech device, improper maintenance can cause more harm than benefit.

The nominal maintenance interval for Molybdenum grid sets is 200 process hours. Past this point, the coating deposited on the grid may begin causing noticible changes in the ion source performance and will decrease grid lifetime.

We recommend media blasting at no more than 40psi air pressure, and with 150 grit alumina media. During the blasting process, the blast nozzle should be held roughly 6 inches from the grid, and ideally at about a 30 degree angle from surface normal. It is even possible to repair the shape of deformed grids slightly using this process! For more information, click here or contact us directly.

As always, if you just don’t have the time or desire to clean the grids yourself, Plasma Process Group offers a quick service to clean them for you!

Please note – it’s not a great idea to media blast graphite grids. Any Molybdenum or Titanium grids from Plasma Process Group are fine to media blast. Chemical cleaning is not recommended due to the nature of the chemical solutions used. These chemicals are dangerous, toxic, and can leave significant contamination on the grids after cleaning unless used exactly correctly.

We Have The Power!

Just when you thought it was safe to go back in the lab, lurking below the surface of your coating system is an ancient power supply that could die at any moment! You thought you could repair him, but suddenly, no one makes that part anymore! What will you do? No old coating chamber is safe!

But seriously, movie-trailer openings aside, a critical component of your coating systems is at its end-of-life: the power supply. Perhaps you’ve noticed the increased failure rate, the extra downtime, but you’ve been hobbling along by getting them repaired more and more often. Unfortunately, the time has come to retire those old supplies. Even we can’t get the parts anymore, and for that reason, Plasma Process Group is announcing the end of their Power Supply Repair service for the Ion Tech series effective January 1st 2016.

Don’t panic – We have a solution! The I-Beam Series of Power Supplies! The single-unit I-Beam is designed to replace that giant cluster of Triassic-era power supplies you are currently using. With a familiar, intuitive interface and dramatically simplified connections, our I-Beam power supplies can drop-in replace your existing, aging units. Communications are standardized, so your system won’t even know anything has changed. Even better, since the entire power supply is contained in one single unit, we’ve eliminated all those excess communications cables!

I-Beam units have been running in foreign and domestic coating labs for over 8 years. We manufacture the entire power supply in-house. All of our power supplies are subjected to rigorous tests including vibration and 24+ hours burn-in. Most importantly, each power supply is run on an actual ion beam source in an actual vacuum chamber under actual process conditions. When it leaves our facility, it’s ready to work at yours!

Call us today and ask about the I-Beam Series power supplies for both your DC and RF Ion Beam sources.

Replacing your RFN Collector

     Collector replacement should happen each and every time your RFN is cleaned. The collector in your RFN is fabricated of Nickel that can react with Oxygen when it gets hot. Unfortunately, these reactions occur both on the surface and deep inside, meaning that a collector cannot be “cleaned” like other RFN parts. Conventional cleaning methods, such as media blasting, will not remove the oxide deep in the material. Consequently, reconditioned collectors will not have the expected 2000+ hours of operational life.

     Installation of a new collector can also be a tricky procedure. Perhaps you have replaced your collector before, but then struggled to get the RFN to tune correctly? This may be because your collector was not tight enough! The collector has a capacitive relationship in the RFN circuit, so the spacing between it and the RF antenna coil makes a significant difference in how the circuit works. Small gaps or movement between the collector and the discharge chamber will have a negative effect on the RF tuning. It is very important that the collector has a snug fit when installed. For more detailed information, click here.

     When you send your RFN to Plasma Process Group for a refurbishment, we custom-fit a new collector into the discharge chamber, giving it the tightest and most stable fit we can. We have the experience to know what the appropriate insulator lengths for specific hardware are, providing the longest time between cleaning cycles and the most stable tuning and operation.
