The printed circuit boards (PCBs) used in electronic components are susceptible to the negative effects of external conditions, which may result in short circuits or system failure. The introduction of conformal coatings technology is being driven by rising worries among electrical manufacturers about protecting the board and its components from moisture, chemicals, salt spray, and temperature variations.
Electronics shrinking has resulted in complicated circuit design, necessitating the need for ultra-thin insulating conformal coatings to enable for PCB conductor spacing reductions. In order to enable quick manufacturing output with a minimal margin of error, coatings technology with full cures in short times is a priority.
At the moment, solvent-based polymer conformal coatings technology dominates the market; nevertheless, it has limitations in terms of chemical and electrical performance under demanding working circumstances. Stringent emission standards are driving the removal of solvents containing high levels of volatile organic compounds (VOCs), and the industry is transitioning to UV/LED curing technologies and the use of cost-effective automated systems. Material technological innovation, such as composites, nano, and bio-based materials, as well as the integration of cutting-edge application systems and improved curing systems, will open up new prospects for industry players.
The method of applying conformal coatings is crucial in terms of delivering an acceptable degree of protection based on system design and material selection. There are a variety of commercially available technologies that may influence the depth of the coating applied, the amount of coverage needed, and the coating adherence to the board and its components. Conformal coatings application technology is evolving rapidly since brushing, dipping, and hand spraying are labor-intensive and time-consuming operations.
With human participation, the likelihood of faults increases, which may result in production delays and expensive rework costs. To satisfy increased demand, the development and installation of automated systems such as selective needle dispensing, ultrasonic coating, selective film coating, selective tri-mode coating, and precision jet coating will allow quick throughput. Industry players will profit from the use of hybrid deposition methods that provide increased film thickness and composition consistency for complicated designs.
