Plasma Technology befor Bonding Cleaning of metal Activation of plastics low-Pressure Plasma
Plasma Cleaning of Surfaces
1. Cleaning of Surfaces (Before Bonding,Soldering Orgluing)
2. Activation of Surfaces ( before printing ,Vanishing,Orgluing)
3.Etching of surfaces(before micro sturucturing of silicon or etching of PTFE) sand blust
4.Deposition of surface -Plasma polymerization. (deposit of hydrophobic/hydrophilic layes)
Deposition of surface -Plasma polymerization. (deposit of hydrophobic/hydrophilic lays)
How does a low-Pressure Plasma system work?
The component for treatment is exposed to plasma. The plasma system receives continuously fresh gas whilst contaminated gas is sucked off.
One option of varying parameters is the volume of the recipient. The chamber size is configured according to size quantity of the component to be treated. Large recipients can have a volume of 10,000 ltrs and more. Laboratory systems have a volume in the range of 1 to 50 ltrs. The method of plasma creation
Standard applications are carried out without charge.
Examples of sample parts / product groups
1.1 Cleaning of metal
Some components are covered with grease, oils, wax and other organic or inorganic contaminants (also oxide layers)
a) Soldering under vacuum: no flux is required
b) Long-term stored electrical components, which have oxidized over time. Oxidation can be eliminated by hydrogen plasma.
Often organic contaminants, in example, residual of Electroplating processes, of adhesives, of flux residuals. disturb bonding. this can be removed by plasma. (oxide layers can worsen the bonding process.)
2. Activation of plastics
Polypropylene of PTFE (Polytetrafluoroethylene) are themselves of homopolar structure.
3.1 Etching of metals
Aluminium using chlorine
3.2 Etching of plastics
Etching is very important with plastics, which are difficult to lacquer and to glue, like POM or PTFE.
