ETEMCO, a U.S.-based electronics manufacturing company providing PCB assembly, testing, and electromechanical manufacturing services for industrial and high-reliability applications, provides conformal coating and RTV dispensing services for PCB assemblies designed for harsh operating environments. The company applies conformal coating to printed circuit boards to protect against moisture, chemicals, dust, corrosion, oxidation, vibration, and temperature extremes.

To support conformal coating services, ETEMCO added a PVA Delta 8 4-axis conformal coating and RTV dispensing machine to its factory. The system is used for automated conformal coating and RTV dispensing applications.
ETEMCO's conformal coatings are used to protect PCB assemblies from moisture and dust that can lead to corrosion, short circuits, heat retention, and reduced reliability. The company also noted that coatings help protect solder joints and component leads from oxidation and corrosion over time.
For high-vibration environments, ETEMCO uses RTV dispensing to secure larger and heavier components, including electrolytic capacitors and transformers, to reduce vibration-related stress on assemblies. RTV silicone is also used to absorb shocks, vibration, and thermal expansion while maintaining PCB electrical functionality.
The company said conformal coatings are available in acrylic, epoxy, silicone, and urethane materials. ETEMCO also offers parylene conformal coating services for projects requiring thin and uniform coverage. Selective coating application is used to protect specific PCB areas while avoiding connectors and components that require exposure.
According to ETEMCO, conformal coating is integrated into PCB assembly workflows to provide protection during manufacturing. The company also stated that RTV dispensing can be integrated into existing production flows without specialized handling requirements and can conform to irregular shapes and hard-to-reach areas.
ETEMCO said its conformal coating and RTV dispensing services are intended for PCB assemblies operating in environments exposed to moisture, vibration, contaminants, corrosion, and thermal stress.
