Vacuum potting for maximum performance

Air bubbles in the potting material impair the performance of electronic components. In many applications – especially in the automotive and electronics industries – this is a complete no-go.
There can be absolutely no bubbles in these components, so the focus here is on potting in a vacuum.

There is a commonly held belief that this technology is too complicated, too expensive and too slow. But that is not the case at all, as you’ll see.

So when is potting in a vacuum advisable?

Our short checklist will help you determine whether vacuum potting is right for your project.

Entscheider: Vakuumverguss

Entscheider

Miniaturisierung

The spaces in the component to be potted are extremely small, and bubble-free potting under atmospheric pressure is not possible

Bauteildesign

The complex structure of the component (e.g. many undercuts) does not allow for bubble-free potting under atmosphere pressure

Hochleistungsanwendungen

Sensitive electronics must be fully and reliably protected from outside influences (moisture, dirt, etc.) to ensure sustainable use of the product

Sicherheit, Zuverlässigkeit

The potted electronics perform safety functions

Funktionsqualität, Hochleistungsanwendungen, Zuverlässigkeit

The potting is part of component thermal management, i.e. heat must be reliably dissipated

Funktionsqualität, Zuverlässigkeit

Potting is intended to reduce thermal stresses in the component

Hochleistungsanwendungen

Potting is intended to reduce the fire hazard of a component

Funktionsqualität, Zuverlässigkeit

Potting is intended to protect against corrosion

Wickelgüter, Hochspannungsbauteile

Potting in a vacuum is to be used for components for which that method is becoming more and more the default option (stators, regulators, transformers, insulators, unprotected wire coils and enameled copper wires)

In many applications, air bubbles can be tolerated to a certain extent from a functional point of view. Your application does not yet absolutely require potting in a vacuum.

If one or more items in the checklist apply to your products and therefore their potting requirements – whether that’s because you’ve had some bad experiences before or because you really don’t want to take any risk – then vacuum potting will give you the results you’re looking for.

bubble-free potting

Increasing quality requirements and workpiece complexity or added degrees of freedom in design and engineering are just some of the many reasons to choose vacuum potting. Scheugenpflug vacuum dispensers were designed for cost-effective batch production at the highest levels of quality. All VDS systems feature a dispensing unit for 1C or 2C potting media, depending on your needs.
