Generally, the surface energy of metals, ceramics and glass is higher than that of plastics. Nevertheless, there are also applications where these materials benefits from [**plasma activation**](https://www.thierry-corp.com/plasma-activation?hsLang=en). The surface tension of **solder alloys** is likewise high, they roll off many metal surfaces. Therefore, plasma activation of metals can also improve **wetting during soldering**.

However, activation of metals is highly **unstable** and thus has a **short duration of action**. Once metal has been activated, further processing (gluing, painting....) must take place **within the next minutes or hours** because **contaminations** from the ambient air will become attached to the **surfaces** fast and permanently.

**Metal activation** makes sense before processes such as **soldering or bonding**.
