UV cure conformal coating of electronic assemblies

UV cure conformal coating of electronic assemblies

Environmental influences such as heat or humidity can impair the function of electronic components or even destroy these components. To guarantee their function for a long time, conformal coatings are applied to electronic components which are cured within seconds using UV LED radiation.

The components can immediately be processed further and UV curing makes them especially resistant to environmental influences.

UV curing is used in many other applications in the electronics industry, e.g. to cure UV-curing paints used to mark smallest parts or adhesives used to glue mobile phone displays.

Your advantages with UV curing:

  • Increased production rates
  • Reduced work-in-process
  • Protection of sensitive components and substrates
  • More durable and reliable products - increased abrasion and chemical resistance, higher bonding strength of dissimilar materials
  • Low energy and space requirements

UV curing is used for:

Applications of LED curing
  • Conformal coating of printed circuit boards (PCB)
  • Cable assembly and marking
  • Bonding (optically clear adhesives) and sealing of cell phone and other displays
  • Wire tacking, die and pin attachments
  • Precision bonding of miniature components such as micro-speakers, camera modules, and disk drives
  • Encapsulation of chips and other electronic components
  • Sealing and gaskets on electronic enclosures
  • Glob tops on PCBs
  • Markings on cables and electronic components
  • Printed and flexible electronics
  • Semiconductor fabrication
