Since 1993 Diener electronic of Nagold, Germany has been producing 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.
In the electronics industry low pressure plasma is commonly used for cleaning of wire bonding pads prior to bonding. The plasma cleaner produces a much stronger, more reliable bond. Also lead frame strips may be cleaned prior to die bonding producing a strong homogeneous bond for improved thermal characteristics. Plasma cleaners can also be used as “ashers” to remove photoresist from semiconductor wafers.
The plastics and adhesive industry finds wide application for surface activation using both low pressure and atmospheric plasma. Since plastic surfaces are typically hydrophobic, plasma machines can be used to “roughen up” the surface and make it more hydrophilic so that plastics can be painted or coated, and also so that they can be glued or bonded together reliably. Many automotive manufacturers use plasma surface activation to treat plastic parts prior to painting or glueing.
The medical manufacturing community uses plasma systems for surface activation and also coating. In a typical application the surface of catheters are treated prior to ink marking, providing a good surface for ink adherence. Catheters may also be coated with a polymer-like material that makes the interior hydrophobic for better liquid flow characteristics and less prone to infection. Surface activation prior to gluing parts together is also a common application. This pretreatment assures a solid and reliable bond.
Diener electronic produces a wide selection of both low pressure and atmospheric plasma surface activation machines, the smallest machine being the Femto that provides an economical laboratory scale machine and can be purchased for less than $8500 including the vacuum pump. Very large production machines for processing large or high volume parts are also available.
The PlasmaBeam, an atmospheric plasma machine, produces a plasma “flame” that emanates from a small plasma pen that can be held manually or manipulated robotically. This machine can find application in many industries where the use of a vacuum chamber is not desireable. This unit is very versatile and can be operated with compressed air, nitrogen, or oxygen. Having a price tag of less than $9500., the unit is a very affordable solution to many cleaning and surface activation problems.
Located in Reading, PA, Diener electronic – North America was created to provide a sales, support, and service organization to address the needs of American industry. The Pennsylvania facility includes a demonstration laboratory where customer samples are treated at no cost to prove the efficacy of the plasma systems. Please contact us for more information!
