In this paper, the different sources of interference are explored, as well as how coatings can play a critical role in protecting these sensitive components and boards.

Dual-Curing Adhesives
For a UV curable adhesive, the cure initiates after exposure to UV light at a wavelength that is specific to the photo-initiator used in the formula. A dual cure adhesive has the UV light cure as the first step in the process, followed by a secondary thermal cure achievable at temperatures as low as 80°C. This dual cure process benefits a wide variety of bonding, coating, sealing and small encapsulation applications. Learn more about the advantages of dual cure adhesives and how they may enhance the performance properties required in your application.
