Plasma etching applications

Plasma etchers can be used to show failure analysis

A form of plasma processing used to fabricate integrated circuits is called plasma etching. A high-speed stream of plasma discharge or glow with an appropriate mixture of gas being shot in pulses at a sample truly defines the plasma etching. Antoher technique to surface treat, is to use liquid etchers. However, this comes at a environmental cost, and is often a lot more costly. REad more about that in this article. The source of plasma known as etch species can be charged ions or atoms and radicals that are neutral. During the plasma process volatile etch products are generated at room temperature from the reactions of chemicals between the elements of the material etched and the reactive species that has generated the plasma. Furthermore, the atoms eventually embed themselves at or just below the surface of the target and this modifies the target’s physical properties. This is a very environmentally safe method.

Calibrating your measurement microphone

admin News 0 Comment

Measurement microphones are, of course, designed to take measurements with scientific accuracy. In the same way that you wouldn’t use a microscope without first calibrating it, the same applies to the microphone equipment you’re using too.

What is calibration?

Simply put, calibration is the fine tuning to the set up of your equipment to maximise performance and accuracy of output. Just as Formula One engineers will calibrate their tyre pressures for optimal grip and durability, by calibrating your microphones and equipment, you can ensure consistent performance and measurements.

Benefits of Using Plasma EPDM Profile Treatment

Benefits of Using Plasma EPDM Profile Treatment

EPDM rubber is commonly used in the automotive industry to make several parts of vehicles including the seals of doors, the trunk, the hood, and the windows. It is also used for other purposes such as temperature controlling because of its insulating properties. Practical uses of EPDM rubber include cold rooms, radiators, garden appliances and electrical insulators, tubes and hoses, washers, solar panels, speakers, and headphones.

EPDM rubber can either be conductive or non-conductive which is why plasma treatment is needed to activate it and to achieve a strong bond between the rubber and the adhesive during the flocking process. It is also needed to wet the rubber in the slip coating stage to obtain the desired properties for adhesion. Plasma treatment is used as a replacement of chemical treatments as chemicals are generally dangerous, low yielding, and high in cost. Read more

Adhesive Bonding – Techniques and Considerations

A technical synopsis of different methods of adhesive joining

Adhesives are considered as one of the most reliable options for joining two substrates together. Unlike other methods of bonding, adhesives keep the geometry and properties of the materials intact. The technique has considerably matured over the years and every industry relies on adhesive bonding to produce high quality products.

Techniques

Most substrates like metals and polymers are not wettable by adhesives and require some pre-adhesion treatment. There are a number of surface preparation techniques for making materials suitable for adhesions. Some of the commercially used techniques are: Read more

Adhesion and plastic surface treatment

admin Plastic surface treatment , ,

The Adhesion problem is common in materials that possess low surface energies. Examples can include High-Density Polyethylene, Polypropylene, EPDM, and Polyethylene etc. With the surface energy ranging anywhere from twenty nine to thirty six Dyne/cm or mN/m (milinewton per meter).

Obtaining a level of adhesion on any materials with low surface energy i.e. Polypropylene or Polyethylene etc. can sometimes become extremely difficult because of their slickness. Thus, this adhesion problem leads to the printed ink rubbing off, coatings or paint not sticking on the surface along with failed gluing and weak sealing.

Sometimes it is important to treat various different plastic surfaces. Therefore you should always look for the best solution.

In our opinion, there is a need to look for something that:

  • Is green (Greentech/green technology)
  • Presents ROI (Return on Investment)
  • Can be customized

The popular Red cups are also surface treated

The popular Red cups are also surface treated

In parties and rites of passage into “adulthood, by” we drink beer, wine and liquor. We normally use the red cups. A good thing about them is that they regulate the drinking and have a convenient gauge for alcohol pourage. We need not stress ourselves up since the red cups have lines that are a measurement of the rate of drinking. These plastic party cups’ lines are three with reasons;

  1. Bottom line-Is a line for liquor.
  2. Second line-Is a line for wine.
  3. Top line-Is a line for beer.
