PLASMA (PVD)


Plasma treatment refers to the use of an ionized gas to increase (hydrophilic) or decrease (hydrophobic) the energy of any surface at either low pressure or atmospheric pressure. It is commonly used as a preparation method for many types of coatings.  In some instances it is an excellent pre-treatement for Parylene.  Often the gas used is similar to atmoshperic air, although an oxygen-rich gas can be used for an enhanced effect.


Lately, it is used in the textile industry to achieve hydrophilisation or hydrophobisation. It has other positive effects also, like improvement in adhesion and the accumulation of functional groups to the surface.


Surface Activation

Surface activation prior bonding has the advantage that no intermediate bonding layer is needed and sufficiently high bonding energy is achieved.  Typically this is achieved at low temperatures.  In most cases no activation is needed when coating with Parylene, however we have several processes available should it be required by the substrate.

Surface Preparation

Our advanced cleaning technology is ideal for preparing parts for a subsequent coating such as Parylene.


In many cases residual solder flux and other contamination can affect the quality and life of a Parylene coating. We will often recommend cleaning circuit boards to maximise their service life.
