Plasma Cleaning of Surfaces

Applications

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)

PLASMA  SURFACE MACHINE

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.

Applications

Cleaning

1.1 Cleaning of metal

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.

Bonding:

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.  Etching

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.

4.  Coating by plasma polymerization
