Finishings

Guaranteed protection and durability
for your PCBAs

Not all PCBAs work in the same way and in the same type of environment, and therefore the same coating material is not always suitable and the same level of protection is not always required. The finishing of the PCBs must also be customized.

In order to respond to each of our customers’ needs, TEF offers a series of finishings designed to optimize the protection and performance of different types of PCBAs.

3 TEF finishing options for your PCBAs

1. Selective varnishing

We apply varnish precisely and selectively on the defined areas of the circuit.

Why choose varnishing? This finishing protects key components, ensuring reliable performance in controlled environments.

2. Silicone coating

Silicone insulation provides a superior layer of protection against:

Shocks and vibrations.
Extreme temperature changes.
Moisture, dirt and other corrosive agents.

When is silicone coating the right option? This finishing is ideal for extending the life of PCBAs operating in demanding applications.

3. Curling

The coating seals the electronic components, ensuring total resistance to moisture, dust and other environmental threats.

In what cases is curling more advisable? This finishing is perfect for ensuring complete watertightness and protecting PCBAs operating in extreme conditions.

In the design and application of finishings, we tailor to the conditions of use of each PCBA and its technical specifications. After the varnishing, silicone or resin coating applied by TEF, silicone coating or TEF’s sandblasting, your PCBAs will be ready and in optimal conditions to work at maximum performance in the required operating environment.
