Protecting PCBs with protective varnish is an effective way to extend the life of electronics and protect circuits from environmental factors such as moisture, dust, chemicals or vibration. PCB varnishing avoids failures due to corrosion and short circuits, particularly important in industrial, automotive or IoT applications where devices operate in demanding conditions. It is important to choose the right type of varnish, taking into account the specifics of the device and its operating conditions. Proper protection not only guarantees the reliability of the equipment, but also reduces service costs in the long term.
