PCB Cleaning for Harsh Environment Electronics
Electronics exposed to salt spray, industrial pollutants, or extreme humidity require stringent cleanliness and protective strategies. Removing corrosive residues and adding protective coatings preserve functionality in harsh locations.

validate with accelerated corrosion and humidity tests
-
maintenance schedules for field-cleanable designs
Challenges in harsh environments
Contaminants accelerate corrosion and electrochemical migration under humidity and bias. Outdoor enclosures trap salts and biological deposits which attack metal surfaces and solder joints, shortening service life.
Effective cleaning solutions for harsh conditions
Combine precision cleaning, conformal coating, and desiccants for sealed enclosures. Use corrosion-inhibiting cleaners where appropriate and validate with salt fog and biased humidity testing. ZESTRON provides chemistries and testing programs to qualify processes for harsh environments.
