UV Technology for Printed Electronics

Tuesday 21. May 2013 - Reliable curing for a future technology

From June 11-13th 2013, LOPE- C will take place in Munich for the second time. This leading fair shows the enormous progress in an emer- ging technology, regarding end products and especially regarding manu- facturing processes. The difficulty lies in the various materials which have to be accomplished, usually in several steps. Central importance lies on the right curing process.
Dr. Hönle AG is a worldwide acknowledged expert for UV curing technology. For more than 30 years Hönle has been developing UV systems for the graphic industry, but also for various applications in the field of electronic manufacturing. One of the greatest advantages of UV technology for printed electronics is the complete curing of the polymer materials within a split second. Thus, immediate further processing is possible. In addition, UV curing can be applied even for temperature-sensitive substrates, as e.g. thin foils – by using sophistica- ted reflector geometrics or LED variants. The possibility to match irradi- tion times and performance exactly to application and substrate makes UV curing very efficient, in any respect.
At LOPE-C Hönle show their broad range of UV and UV-LED curing systems. The products of the innovative jetCure-series provide for outstanding curing results, even at high speeds. This leads to advanced printing quality.
jetCure units are equipped with cold mirror reflectors for temperature- sensitive materials and available with adjusted lamp spectra. The length of a jetCure can be individually matched to any printing process. As customized as possible!
UV-LED technology
UV-LED technology gains importance for printing but also for bonding applications. One reason for its success is the very long LED life-ser- vice. Another is the fact, that LEDs can be switched on and off as often as desired, without any heating or cooling phases. Perfect for cycled operation!
LED-trendsetter Hönle offers a wide range of high-end UV-LED curing systems. They are available with the wavelengths 365/385/395/405nm +/- 10nm and with intensities up to 16 W/cm2.
Products of the LED Powerline-series allow a high-intensive UV irradia- tion. They are available in different irradiation widths (from 76 up to 1.500 mm) and wavelengths and can so be optimally matched to any application. Due to their huge success, Hönle has been further develo- ping their LED Powerline continuously, always in close cooperation with the users. Thus, today the product line comprises of a multitude of process oriented variants:
LED Powerline LC – Liquid Cooling LED Powerline IC – Integrated Control New: LED Powerline HP – High Power New: LED Powerline AC – Air Cooled
New: LED Cube 100. The emission spectrum of this compact UV irra- diation chamber can be adjusted to versatile processes by applying different LED lamp units. It is especially used for bonding and sealing components in electronic manufacturing processes. A reflecting inner surface and optimized reflector geometrics provide for a homogenous irradiation and a high process reliability.
The LED point source bluepoint LED has been developed for all appli- cations which need a high-intensive UV irradiation. The possibility to program complete process sequences, e.g. exposure times with different intensities and holding times, allows shortest cycle and machine throug- hout times.
Key components made by Hönle To guarantee their customers best quality, Hönle manufactures all important key components themselves: UV lamps and reflectors as well as electronic power supplies. This results in customized UV curing systems for highest process reliability.
