Surfx Technologies at Semicon® Europa

Surfx at Semicon Europa

Surfx Technologies at Semicon® Europa

Surfx will be exhibiting at Semicon® Europa in Munich on November 14-17, 2017. We will introduce our new product, the AtomfloTM 500 outfitted with a 100-mm-wide argon plasma head. Please come see us at booth B1.1602, hosted by Novel Technology Transfer GmbH.

The 100-mm-wide argon plasma is truly a unique product that provides customers with the highest possible throughput for in-line surface treatment. The plasma is a capacitive discharge that uniformly fills the exit slit with a high concentration of reactive species. It provides for variable chemistry by selecting the process gas to feed with the argon. For example, 1.0% oxygen in argon rapidly cleans and activates glass, ceramic and polymer surfaces for bonding. By contrast, 1.0% hydrogen in argon quickly removes copper oxide from copper for subsequent die attach and wire bonding to lead frames.

The AtomfloTM 500 atmospheric pressure plasma system is an outstanding product for in-line surface treatment. It comes with the following features: low voltage, low temperature, handheld or robot driven, two process gas lines controlled with digital MFCs, automatic tuning of the RF matching network, and real-time monitoring and control of all the process parameters.

I look forward to seeing you at Semicon® Europa!

Handheld plasma treatment for surface preparation or bonding

How does it work?

Short version: it seems like magic but the plasma is chemically modifying that top few layers – putting on high energy groups allowing for the adhesive or paint to form a chemical bond.

handheld-plasmaFirst off, what is plasma? Plasma is ionized gas, which is highly reactive. The handheld plasma treatment system (shown in picture) will deliver this highly reactive gas directed to your materials. The plasma will do multiple things simultaneously as you hover this tool across your substrate: 1) clean the surface free of organic contamination, 2) the reactive atoms will insert itself onto the top molecular layers of your surface, and 3) also etch the top molecular layers very slowly.

Yes, that is someone’s hand on the pistol grip handle and it is quite safe to use when you are that close to the plasma. The wheels allow the user to freely guide on a large (relatively flat) surface while maintaining consistent distance between plasma exit and substrate. In between the two wheels, you see a bright strip. That is the plasma glow discharge (it gives off light when it goes from excited state back down to neutral state). The distance and the speed at which you guide the tool will matter and is highly dependent on the material.

How does plasma do those three things happen and how can you tell?

When you do hover the tool over your substrate, you will not see any physical changes (as you would sanding or grit blasting). Remember, this is happening to the top layers, which is very thin and is not visible to the naked eye.

Organic contamination consists of hydrogens and carbons. Our plasma will usually be used with oxygen based plasma – meaning it will generate very reactive oxygen atoms. When the oxygen combines with 2 hydrogens, it will form water. However, the amount is so small that it volatilizes from the surface. Carbon contaminants will form carbon dioxide, which is a gas form so that flies off the surface.

The material does get etched very slowly because the reactive oxygen atoms are not selective. If you provide enough time and enough reactive oxygen, it will etch through almost anything. So damage to the part is not a concern with our atmospheric plasma technology.

Once the part has been treated, there will be no visual change. The quickest way to tell is by dipping it in water (water break free test) or putting a droplet of water down on the area that has been plasma’ed and compare to another droplet of same/similar size down. This is the quickest and most qualitative way to demonstrate that your surface has been plasma cleaned/treated. What you should expect to see is the water droplet sheath out much further on the cleaned surface compared to untreated. Water is a polar molecule and is attracted to other polar components, thus spreading out more on the oxygenated surface.

Now, if you want quantitative data, then I would recommend a cost-effective portable goniometer such as the Kruss Mobile Surface Analyzer (MSA). The MSA can be utilized in a lab setting or on the production floor. It takes a total 3-5 seconds to do the following: place two droplets (water or another liquid), take contact angle measurements, and the software to calculate the polar and dispersive components of the surface free energy.

Don’t hesitate to reach out if you have any questions.

Surfx Plasma For Balloon Catheter Assembly

From shaft coatings to balloon bonds, the catheter manufacturing process features many steps that can be improved by Surfx plasma treatment. Our variety of plasma source geometries and operating gases allows you to deliver highly reactive gas to your substrate, no matter the size or length. Surfx brings your process out of the chamber, activating polymers and metals in line, at atmospheric pressure.

Solvent wiping a meter long shaft introduces a high level of variability in coating performance. Instead, clean and activate your shafts (again, of any length) using a tubular Surfx plasma source. Feeding the shaft through the source removes surface organic contaminants and oxidizes all 360 degrees of the clean shaft surface. The now-active shaft can then be immediately coated and you can achieve maximum performance of your device.

Activating the interior diameter of balloon necks prior to joining them to shaft is another great application for Surfx plasma. Our low-temperature reactive gas flows into the balloon, cleaning and oxidizing the ID of the neck without thermal or chemical damage. Are there integrated sensors and wires into the balloon? No problem! Thanks to the unique design of Surfx plasma sources, all charged species are held within the plasma source. Only electrically neutral, but chemically active gas is allowed to flow out and treat your part. That means you can treat active electronics and metal components embedded in balloons without risk of damaging the electronics or puncturing the balloon with a spark.

These are just a few implementations of Surfx plasma that can offer vast improvements over traditional treatment methods and enable devices to be constructed in unique ways. If you have a need for surface modification, please don’t hesitate to give us a call. I look forward to offering you a surface preparation solution!

Best atmospheric plasma on the market

Surfx invites you to compare our product to other atmospheric plasmas on the market. Here’s why we think we are the best:

1) Speed – For treating large areas, Surfx’s AtomfloTM plasmas cover more ground faster than any other competing product. Speed means higher throughput, which lowers cost.

2) Uniformity – Surfx’s plasma sources are uniform across the beam. You obtain precision treatment of your materials with minimum overlap between scans. In other words, more value at lower cost.

3) Plasma chemistry – Surfx’s proprietary atmospheric plasmas allow you to blend oxygen, hydrogen, nitrogen, or other gases with argon to tailor the process chemistry. Oxygen plasmas are used to activate plastics for bonding, whereas hydrogen plasmas may be used to remove copper oxide from lead frames. The Surfx AtomfloTM plasma tackles many tough materials problems, more than any other competing product.

4) Low-temperature – Surfx’s patented design produces a radio-frequency (RF) capacitive discharge, which yields a highly efficient, cold plasma. Standard water-cooled sources generate reactive gas flows at between 60 and 100 oC. The most thermally sensitive materials, such as polyethylene and polypropylene tubing, are treated without any risk of thermal damage.

5) Control – The AtomfloTM controller is a PC-based system with continuous monitoring of forward and reflected power, mass flow rates, and plasma intensity. Digital mass flow controllers and an advanced auto-tuning matching network provide precision process control within user selected limits. Your parts are treated the same way, day in and day out, no matter which machine your using. No other atmospheric plasma system provides the same level of control. The benefit to the customer is greater product yield, i.e., more value at lower cost.

6) Safety – Surfx’s RF capacitive discharge operates at low voltage with no risk of electric shock. You may run the plasma by hand or with a robot, whichever method minimizes your cost. If hydrogen plasmas are required, you need not worry about fire or explosion. Surfx’s AtomfloTM runs with standard blended gases, e.g., 2% hydrogen in 98% argon, where there is no safety risk.

Based on speed, uniformity, chemistry, temperature, control and safety, Surfx has the best atmospheric plasma on the market. Contact us for a free demonstration. We are confident we can deliver the best solution at the lowest overall cost of ownership.

Plasma coatings for medical plastics

Injection molded plastic parts are key components of medical devices, molecular diagnostics, microplates, catheters, surgical instruments, and other emerging technologies in medicine and cell biology. When selecting a particular plastic for an application, the design engineer has to take into account many constraints, including resin properties, shrinkage, part complexity, wall thickness, mechanical strength, impact strength, thermal stability, opacity, surface finish, color, etc. Once the resin has been selected, and the molded plastic parts made, another set of design issues arises:

A) How do I glue my parts together and obtain sufficient adhesion?

B) How do I achieve proper fluid flow through small channels without trapping bubbles?

C) How do I promote cell growth on some surfaces, but not on others?

D) How do I make surfaces that remain hydrophilic throughout the product’s shelf life?

E) How do I control wetting on diagnostic surfaces?

These issues all deal with the properties of the plastic surface. When you add the surface requirements onto the bulk material constraints the design objectives can seem overwhelming.

Surfx offers a way for you to tailor the plastic surface to the desired properties independent of the resin selected for the injection molded part. We deposit coatings, 10 to 100 nm thick, onto the surfaces where you need to control adhesion, wetting, cell growth, etc. These strongly adherent, transparent, biocompatible coatings give your product the precise properties it needs at an economical cost. Our atmospheric plasma tools lay down these coatings on the surface of any 3-D plastic part, regardless of the resin type (e.g., ABS, acrylic, liquid crystal polymer, nylon, polycarbonate, polyester, polyethylene, HDPE, polypropylene, polystyrene, and polyurethane). Please contact our engineers so we can help you solve your toughest surface challenges.
