Customer Reviews

The following is a sampling of customer feedback gathered over a period of years. We humbly appreciate these comments and continually strive to surpass customer expectations with each order.

Coating Systems

“Due to COVID it was not possible for Sono-Tek to commission the fluid delivery/nozzle spray system on-site and only remote support would be provided. This unique situation of course made it very challenging for Ballard, but we were very impressed with the remote support provided by the Sono-Tek team (AJ, Shane, Lance, and Bryan). It all started with the detailed documentation, schematics, drawings, and special installation instructions complete with easy to follow photos + diagrams. And the availability to conduct Zoom calls and walk us through the training and troubleshooting was excellent. Response time was very quick including shipping us out replacement parts during the commissioning process. The system is now running in Production. Thank you!”
Ballard Power Systems


“Great technical support.”
Johnson Matthey Fuel Cells – UK


“The support with the set up was better than any supplier I have purchased from.”
Rochester Institute of Technology – Rochester, NY USA


“Sono-Tek is a supplier of an advanced coating system which can be modified according to customers requirements. The staff has a very professional way of handling sales, contracts, installation and following up.”
SINTEF – Oslo Norway


“Sono-Tek leads the way in coatings technologies. Their machines are simple yet effective and can coat better than most traditional systems I’ve seen. This is why I have gone back to them twice since buying my first system.”
UTC Power – South Windsor, CT USA


“The purchase of the SonoTek ExactaCoat and AccuMist Ultrasonic Nozzle has had a very important impact on membrane electrode assembly (MEA) fabrication procedures at PaxiTech. The ExactaCoat and AccuMist Ultrasonic Nozzle allowed us to increase our production capacity considerably and will also assist us in our technical preparation for a completely industrial automated MEA fabrication process… The change to SonoTek has improved MEA fabrication efficiency, productivity, precision and reliability without any loss in fuel cell performances.”
PaxiTech SAS – Grenoble, France


“Easy company to work with, quality product.”
ERA – Arvada, CO USA


“Sono-Tek has superb customer service and is thoroughly upfront and honest.”
Tyco Electronics – USA


“(The ExactaCoat system) has significantly reduced the time that I was spending on making PEM fuel cell electrodes using air brush… In addition, I found Sono-Tek to have great service and support, they really work closely with you before and after you get the equipment.”
University of South Carolina – SC, USA


“After technical discussion and proposals, it was apparent Sono-Tek had the options and technical knowledge to help us select the correct FlexiCoat configuration we needed. As we are required to work with a variety of thin film coating technologies from nano-particle suspensions and electrochromic polymer coatings, we needed the most flexible system we could get.”
University of Wollongong – AU


“Our experience in working with Sono-Tek personnel starting from sales manager, technical person, to installation engineer was very good. They understood our need and did preliminary testing for us and responded well during the whole procurement process. I would recommend them highly! .”
Argonne National Laboratory – IL USA


“Good people to work with. Very easy to use and works really well.”
Specialized Vascular Tech – CA USA


“Very precise mist control and delivery.”
MIV Technologies Inc. – Vancouver, BC Canada


“We use a Sono-Tek laboratory system for a spray process of aqueous CNT-containing surfactant solutions. After a successful service by Rubröder, the system is working perfectly again. Thank you for your commitment and support.”
Dr. Beata Lehmann – PVD und Nanotechnologie


“We are making very good progress in our startup project. The order situation is steadily increasing and customer feedback is positive. We are very satisfied with your coating system. It runs reliably and flawlessly.”
Dr. Vitali Weißbecker – Julich Forschungszentrum


“So far everything is going fine. We sprayed the first membranes directly onto electrode structures with very good results.”
Dr. Klaus-Dieter Kreuer – Max Planck Institute


“In our institute (ZBT) we have been using a Sono-Tek Spray Coater from Rubröder for several years as part of various R&D projects, including for the development and manufacture of gas diffusion electrodes for PEM fuel cells. The above-mentioned ultrasonic spray system works very reliably and creates homogeneously structured layer structures. The system is also attracting great interest in our company for other applications and is used by several working groups.”
Dr.-Ing. Volker Peinecke – Elektrochemie und Schichttechnik, Zentrum für BrennstoffzellenTechnik


“For the development of hemostatic patches based on NHS-POx, we have seen that very reproducible results (ex-vivo/in vivo) could be obtained with coated patches created with our R&D Exactacoat coating machine. For upscaling, GATT Technologies BV is very interested in Sono-tek’s ultrasonic spraying equipment for production.”
Dr. Marcel Boermann – GATT Technologies BV


“We use an ExactaCoat Inert system for the production of silicon layers in the thin film area. With this system, extremely homogeneous layers with a thickness of a few micrometers can be produced with practically no loss of material. The research project is going well, as is the coating line. So far we have only had minor problems with the glovebox system, but they all could be resolved quickly with the help of Rubröder’s technical service.”
Dr. Roy Buschbeck – Institut für Chemie, Technische Universität Chemnitz

Spray Fluxing


“Your fluxer is great. It has exceeded all expectations. ”
Bose – New England

“Great equipment — good people!”
ACC Electronix Inc. – Normal, IL USA

“This change to Sono-Flux EZ made us more efficient, productive, competitive and quality raised without raising the prices, in general this was a big WIN for Viconics in terms of building high quality products quickly at a competitive price. I always heard that spray fluxing was the way to go, in 2006 when I decided to go with a spray fluxing system I got very disappointed, it was my first experience with a spraying system. Thank god for having experts that build things to work and to last, I had great support from Sono-Tek so far and I have no doubt that this will last. Congratulations to the Sono-Tek team for building what customer wants (Good, reliable, repeatable equipment at a very affordable price), plus they made me appreciate my line of work again !!”
Viconics Electronics Inc. – Quebec, Canada


“Since implementing the Sono-Tek EZ Flux system in our Electrovert Econopak we have seen a dramatic decrease in solder defects after the wave solder operation. The additional benefit of controlling the precise amount of flux with the EZ Flux system has lead to little no-clean residue and drastically reduced the flux consumption from 30 gallons a month to a mere 5 gallons. Maintenance has been reduced from 35 minutes a day to 40 minutes a week further reducing the cost of operation. The system has proven to be easy to setup and use for our operators. Low cost of ownership, small footprint and quick payback make it a great system for today’s high mix low volume environments such as ours. Maybe the most important factor of all is the equipments ability to aid us in our mission of “Continuous Improvement” and increasing the quality that we can offer our customers.”
Altek – Torrington, CT USA


“The reliability of this equipment is excellent”.

“Buy an XL….. You will find yourself finding all your other systems from the other manufacturer substandard.”
TAC, LLC. – Loves Park, IL USA

“Very professional. A pleasure to deal with Sono-Tek”

“Easy set-up and operation.”
Gentex – Michigan, USA
