UV LED array offers cure for industrial tasks
A large area array UV LED curing system has sufficient power to be used as a curing device for inkjet printers and other industrial curing applications.
CIL has always been at the forefront of the development of new electronic manufacturing methods in general and in the packaging of power products and thermal management in particular.
The company has collaborated in a number of research programmes over the past decade with major international companies and research organisations.
A new company, CoolLED, totally owned by CIL, has been set up specifically to exploit the commercial opportunities of this new technology.

Funds enable transition to copper interconnects
The Scottish microelectronics industry's leading-edge IC 'microsurgery unit' has received funds to enable it to introduce state of the art techniques that will make the facility unique in Europe.
The first application area to be addressed is that of UV curing, a technique widely used in the manufacturing industry.
The CoolLED Precision UV LED curing system, is a desktop instrument that generates a large area of high intensity, single peak wavelength of UV light for the curing of inks, coatings and adhesives.
It was developed primarily as a technology demonstrator for the OEM market.
Jenton International, also based in Whitchurch, Hampshire, has been appointed as the UK, European and USA distributor.
Jenton has developed its own range of UV lamp systems that are sold via distributors worldwide and is a company that is committed to UV innovation and international marketing.
CoolLED will also find applications in emerging markets in the industrial and scientific fields that require a high intensity flood of light with a known wavelength and linear area power distribution.
Although LEDs are three times more light efficient than other light sources, only 15 to 20% of the energy is generated as light with the remainder being unwanted heat.
In CoolLED technology, microreflectors are formed as thick copper "islands" plated directly on to a ceramic substrate.
The reverse side of this substrate is also plated with thick copper and bonded to a copper heatsink.
The microreflectors harness light emitting from the sides of the LED, throwing it forward to increase the effective light output and also serve as heat spreaders to improve thermal transfer.
The overall design and construction used in CoolLED technology provides a highly effective thermal structure.
Using this system it is possible to reduce die density while increasing light output and generating less heat.
Extensive research was carried out to determine the optimum cup size and shape.
Once this was established, the optimum configuration proved to be a die density reduced from the maximum of 200 die/cm2 down to 120 die/cm2 that yielded an increased light output by 80% while reducing the generated heat flux by 40%.
Nick Edwards, a Director of CIL and Managing Director of CoolLED, says: "This two year research and development programme represents a major investment for CIL".
"We are encouraged by the response of professionals working in the UV curing industry, our first target market".
"We are convinced that CoolLED has real commercial viability and will become a significant part of CIL's business".
