Bernic introduces new sizes of potting boxes

Bernic has introduced new sizes of Potting boxes intended  for sealing and protecting electronic assemblies. They are made up of polycarbonate  materials that are resistant to shock and vibration.

The Potting boxes named series 7000 are used for safely enclosing electronic assemblies like transformers and chokes. Potting can be done with the help of any solid or gelatinous shock resistant material. They provide a complete protection against moisture and corrosive agents.


Potting boxes are mainly used to protect electronic assemblies. They find a useful application in the development of electronic projects and applications. They are easy tools that engineers can use. They find applications in safeguarding their electronic circuits.

They provide electrical insulation and security to the person handling the electronic assemblies. It gives a thicker and more robust layer of protection. It protects the electronic assemblies from harsh environments.

They also prevent short circuit problems and voltage leakages. They improve the performance and reliability of the circuit.

Potting encloses the whole electronic assembly. They are very much helpful in making the product FIPS complaint.

Potting also prevents unauthorized manipulation of the circuit

Potting is done using various types of materials. Bernic has chosen the superior Material polycarbonate as It heat resistant and have insulating properties


Bernic has 3 unique series of potting boxes for your potting needs. Our potting enclosures are molded from black flame-retardant polycarbonate plastic with a flame rating of UL94V-0. Optional glue-on covers are available as an accessory.

Comprehensive range of open top potting boxes. Maximum protection against shock, chemicals, moisture and temperature. 

  • Encapsulate and protect electronic components
  • Highly resistant to most chemicals
  • High rigidity and impact strength 
  • Compliant with water absorption specifications to DIN53495
  • Tough plastic enclosures for encapsulating electronic components and assemblies

Many sites recommend using silicone or epoxy to protect from impact and loose wires.  Araldite (a brand name) potting compound has been suggested for certain automotive applications

In the potting process, an electronic assembly is placed inside a mold which is then filled with an insulating liquid compound that hardens, permanently protecting the assembly. The mold is part of the finished article and can provide shielding or heat dissipating functions in addition to acting as a mold. A cast assembly uses a removable mold.

As an alternative, many circuit board assembly houses coat assemblies with a layer of transparent conformal coating rather than potting. Conformal coating gives most of the benefits of potting, and is lighter and easier to inspect, test, and repair.

When potting a circuit board that uses surface-mount technology, low glass transition temperature (Tg) potting compounds such as polyurethane or silicone are used, because high Tg potting compounds may break solder bonds as they harden and shrink at low temperatures.
