Protecting Car ECUs and Automotive Electronics from Moisture

Automotive electronics face humidity, temperature cycling, road salt, vibration and the occasional water ingress. A protective coating on the board helps ECUs, sensors and control modules survive years in a harsh under-hood or under-body environment.

Why automotive boards fail

Under-hood heat cycling pulls humid air in and out of modules; over time moisture and road salt corrode tracks and solder joints. A coating seals the copper and pads against this slow corrosion.

What to coat

Engine and body control modules, sensor boards, dashboard electronics and aftermarket modules all benefit. Apply an even layer over tracks, components and solder joints.

Mask connectors and grounds

Mask multi-pin connectors, programming and diagnostic pads, press-fit pins and chassis-ground contacts so electrical connections and serviceability are preserved.

Vibration and salt resistance

Constant vibration fatigues solder joints and salt accelerates corrosion. A reinforced coating that resists abrasion and chemicals helps modules last in real road conditions.
