Background
Parking fees are not one of the most enjoyable things in life, and a malfunctioning parking machine is therefore a major annoyance. The customer, a leading manufacturer of parking meters, realised that protecting the electronics in the machines had to be a top priority to ensure high reliability in harsh outdoor climates, year after year.
Silicone mission
To withstand a harsh outdoor environment with constant temperature fluctuations, from -40°C to +80°C with a high risk of condensation and vibrations from heavy traffic. Easy production and good possibility of post-controls.
Tribotec's solution
TSE3991CU - solvent-free circuit board coating, sprayed over the boards and cured by humidity. Provides a flexible layer that permanently protects all components. The varnish is applied in relatively thick layers, providing very good climate protection, but is faster to produce and weighs less than a total moulding. The coating contains UV indicator for quick control of coating results, and is transparent even in thicker layers, allowing components to be inspected even after coating.
