A demand for PCBs with conformal coatings

1 min read

The conformal coatings market for PCBs reached $8.8billion in 2017 and according to markets intelligence company, Fact.MR, is expected to grow further.

With significant growth in consumer electronics and launch of new machines and equipment, conformal coatings are finding wide application in consumer electronics to enhance the life of the components.Owing to the protection offered to the high performing electronics from environmental conditions impacting circuit performance leading to premature failure, the demand in conformal coatings market for PCBs is likely to grow in the coming years. According to the latest report from Fact.MR, the market is expected to register 5.6% CAGR during 2018-2026.

The report highlights that manufacturers in the conformal coatings market for PCBs are focusing on producing green coating technologies, this is resulting in the growing popularity of the water-based technology as it eliminates the emission of volatile organic compounds.

According to the study, the demand for UV-cured technology is also increasing for protection of PCBs in consumer electronics from harmful radiation. Moreover, non-flammable and volatile organic compounds-free features of the UV-cure technology are also leading to the growing demand across consumer electronics.

With the imposition of stringent regulations on volatile organic compounds emission, manufacturers in the conformal coatings market for PCBs are focusing on minimising emission through their operations by adopting eco-friendly materials and production processes. Moreover, with rising concerns of handling electronic wastes, governments across countries are also undertaking initiatives to reduce e-scrap, thereby, driving demand for eco-friendly coatings in the conformal coatings market for PCBs.

The report also identifies the aerospace as a growing market for conformal coatings due to the harsh conditions PCBs must be able to cope with.

Also driving this growth, is the automotive industry and its increasing use of PCBs in control system, video, audio, navigation system in a vehicle. The conformal coatings market for PCBs is finding wide application in marine, defence, medical, and industrial machinery and equipment industries too.

Cracking and delamination are the two major restraints observed in the conformal coatings market for PCBs, the report points out.

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.
