Conformal Coatings Technology Growth Opportunities

Integrated Electronic Circuitry and Printed Circuit Board Fabrication for Microelectronics Applications Drives Advancements in Conformal Coatings Technology.

The printed circuit boards (PCBs) used in electronic components are prone to the adverse effects of external environments, which may lead to short circuits or overall system failure. Rising concerns among electrical manufacturers to protect the board and its components from moisture, chemicals, salt spray, and temperature fluctuations are driving the adoption of conformal coatings technology.

Electronics miniaturization has led to complex circuit design, which necessitates the demand for ultra-thin insulating conformal coatings to allow reductions in PCB conductor spacing. The need for coatings technology with complete cures in short periods is a priority in terms of supporting rapid production output with a low margin of defects. At present, solvent-based polymer conformal coatings technology dominates the market; however, it is limited with respect to chemical and electrical performance in challenging operating conditions. Stringent emission norms are encouraging the elimination of solvents with high volatile organic compounds (VOCs), and the industry is shifting to UV/LED curing technology and the implementation of cost-effective automated systems. Innovation in material technology, including composites, nano, and bio-based materials, and the integration of cutting-edge application systems and advanced curing systems will create new growth opportunities for industry participants.

The conformal coatings application process is critical in terms of providing an adequate level of protection according to system design and material selection. Various technologies are available commercially, which can impact the depth of the coating applied, the level of coverage required, and the coating adhesion to the board and its components. Conformal coatings application technology is witnessing significant developments as the brushing, dipping, and manual spraying methods are labor-intensive and time-consuming processes. The probability of defects is higher with human intervention, which may result in production delays, and rework costs are also high. The development and the implementation of automated systems such as selective needle dispensing, ultrasonic coating, selective film coating, selective tri-mode coating, and precision jet coating will support rapid throughput to meet the rising demand. The integration of hybrid deposition processes that deliver improved film thickness and composition uniformity for complex designs will benefit industry participants.
