UV LED curing improves bonding and sealing for electronics and medical devices

Bonding and sealing using UV LED curing offers a more reliable process and lower production costs for manufacturers of electronic and medical devices.

UV LED curing improves bonding and sealing for electronics and medical devices

UV LED curing offers all the benefits of traditional UV curing such as fast cure times for higher production rates. However, UV LED curing offers much more:
• even less heat onto the substrate
• smaller form factor for easy integration and retrofitting
• more environmentally friendly since there’s no ozone produced and no mercury

Today’s electronics and medical device process, industrial and design engineers need reliable and consistent UV curing processes that can be easily duplicated anywhere across the globe. UV LED delivers higher first time quality, important for electronics and especially life critical medical devices.

More consistent output over a longer life - UV LED technology lasts much longer with significantly less loss of UV output as it ages -- lifetimes are easily 10 to 20 times longer than traditional arc lamp UV curing technology. And over that time the UV output is much more consistent, both in terms of overall energy output and wavelength emitted. Consistent UV LED output delivers consistent curing of adhesives for bonding and sealing.

Located anywhere across the globe - UV LEDs need considerably less cooling air, so bonding and sealing processes located at higher or lower elevations won’t need significantly different cooling cfm. Even with inadequate cooling a UV LED will typically provide adequate output to meet process needs, though useful lifetime will likely be shortened. In contrast, traditional UV curing systems without adequate cooling typically overheat substrates, or their wavelength output changes enough to affect curing results, and operating life drops. So UV LED curing provides a more reliable and consistent process no matter where it is located across your global manufacturing sites.

Process, design and industrial engineers lower their production costs for bonding and sealing of electronics and medical devices using UV LED technology because it:

  • Uses less energy - 30 – 70% less energy compared to traditional UV curing
  • Has fewer consumable/replacement parts – no ballasts, reflectors, or bulbs to replace
  • Lower maintenance costs - less labor time spent replacing lamps and cleaning/servicing other parts such as ballasts, shutters, reflectors and fans


Applications of LED curing
  • Cable assembly
  • 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
  • Sealing and gaskets on electronic enclosures
