Conformal Coatings Market for PCBs Finds Potential Application in Aerospace Industry

PCBs are widely used in the testing and monitoring equipment in the aerospace industry. Owing to the operations carried out in extreme conditions, PCBs used in aerospace industry require great deal of durability and precision. With a significant amount of turbulence, normal PCBs often get damaged during such conditions, thereby, resulting in the failure and high cost of maintenance. In order to avoid such conditions, the demand for conformal coatings for PCBs in the aerospace industry is growing.

With the significant growth in the automotive industry and increasing use of PCBs in control system, video, audio, navigation system in a vehicle, is also driving the growth in the conformal coatings market for PCBs. Meanwhile, with increasing use of PCBs in various industries, the conformal coatings market for PCBs is finding wide application in marine, defense, medical, and industrial machinery and equipment industries.

Cracking and Delamination in Conformal Coatings to Hamper the Growth of Conformal Coatings Market for PCBs

Cracking and delamination are the two major restraints observed in the conformal coatings market for PCBs. Delamination in conformal coatings usually occur due to the poor adhesion of coatings, it involves the removal of conformal coatings from PCBs leaving the area exposed, thereby, resulting in the damage. Meanwhile, extreme environments and high curing coatings resulting in the cracking is another major challenge facing the conformal coatings market for PCBs.
