Increased demand for PCBs with Conformal Coatings

According to a recent report the conformal coatings market for PCBs reached $8.8billion in 2017 and further growth is to be expected.

The report, from Fact.MR has found that the market is expected to register 5.6% CAGR during 2018-2026 – a welcomed increase by many electronics manufacturers worldwide. So why the increase now you may be wondering? To put it simply, consumers want their electronics to last longer and the best way to enhance the life of their components is to use conformal coatings. Its purpose is to protect electronic circuits from harsh environments that may contain moisture and or chemical contaminants. By being electrically insulating, it maintains long-term surface insulation resistance (SIR) levels and thus ensures the operational integrity of the assembly. It also provides a barrier to air-borne contaminants from the operating environment, such as salt-spray, thus preventing corrosion.

The report outlined some of the key drivers of this increased demand for PCB conformal coating. These are:

  • Increased demand for UV-cured technology to protect PCBs in consumer electronics from harmful radiation
  • Manufacturers focusing on producing green coating technologies
  • Government initiatives to reduce e-scrap driving demand for eco-friendly coatings
  • Aerospace being a growing market for conformal coatings due to the harsh conditions PCBs face
  • The automotive industry and its increasing use of PCBs in control system, video, audio and navigation systems in a vehicle
  • Wider application in marine, defence, medical, and industrial machinery and equipment industries
