Bubble Elimination for PCB Conformal Coating

High-quality Bubble-free Finish for PCB Conformal Coating

Natgraph’s new conformal coating system has been designed for seamless in-line integration, with each module serving a specific role within the curing process, from controlled cooling and heating to advanced light-based curing methods.

The range includes Vacuum, LED, UV, Infra-red, Hot Air and Cooling Conditioning modules, offering tailored solutions for a wide variety of coating chemistries and production requirements.

Our Vacuum Conditioning Module (VCM) is a pioneering in-line solution developed to eliminate bubbles in conformal coatings on printed circuit boards, ensuring superior protection and long-term reliability.

By resolving air entrapment issues commonly found in both water-based and solvent-based coatings, the VCM makes environmentally friendly coating options viable for modern electronics manufacturing.

Get in touch with our technical sales engineers at info@natgraph.co.uk to discuss integration options and see how the Vacuum Conditioning Module (VCM) can benefit your production.
