Voltrium Systems is proud to represent Diener Electronic in the South East Asia Region for their quality plasma systems. Diener Electronic is an innovative company in the field of plasma technology and an international leader in the production of high quality, low cost plasma systems, both low pressure and atmospheric. Receiving worldwide acceptance, these plasma surface treatment systems have found applications in the electronic, plastic, and medical fields.
What is Plasma
When energy is continuously supplied to a matter, the temperature of the matter increases and it passes from solid state to liquid and finally to gaseous state. If the energy supply continues, the existing atomic shell disintegrates and charged particles are created (negatively charged electrons and positively charged ions). This mixture is referred to as plasma or the "fourth state of matter".
In short: Change of the aggregate state under energy supply: solid ⇒ liquid ⇒ gaseous ⇒ plasma
Natural plasma occurs for example in lightning, polar lights, flames, and the sun. Artificially created plasma is found in neon tubes, welding processes and in flash bulbs, among others.
Fields of Application
Plasma is used in applications where it is important to combine materials or to specifically change their surface properties. Nowadays, plasma technology is established in almost all sectors of industry, and new applications are being developed constantly. This future-oriented technology allows for modification of a wide range of surfaces. Thus, many different applications are feasible, for example:
|Materials Cleaning||Activation of Materials||Etching Materials||Coating of Materials|
Ion bombardment cleans surfaces physically (sputtering) and, depending on the gas, also chemically. The contamination is vaporized and sucked away.
Plasma treatment of a plastic surface with eg. oxygen, radicals are being formed which lead to a good adhesion of finish and glue.
Etching of the surface with a reactive process gas, material is removed, vaporized and sucked off. Therefore the surface area is enlarged.
A monomer gas is introduced to the plasma chamber, because of plasmapolymerization, layers will be deposited on the surface.
Advantages of Plasma Technology
Plasma technology exhibits decisive advantages compared to other methods such as flame treatment or wet-chemical treatment:
• Many surface properties can only be obtained using this method
• Universally applicable method: on-line production capable and can be fully automated
• Extremely environmentally friendly process
• Almost independent of geometry, powders, plate materials, non-wovens, textiles, tubes, hollow bodies, circuit boards, etc. can be treated
• Components are not mechanically altered
• Heating of the parts is minimal
• Very low running costs
• High process and work safety
• Particularly rational process
