Alpha to Present on LED Products at Lighting Technology Show

Estimated reading time: 2 minutes

Alpha Assembly Solutions will be presenting information on its LED products for die attach and assembly at the Future Lighting Workshop at the Lighting Technology show on October 10 in Essen, Germany.

Ralph Christ, CTS Manager for DACH Europe for Alpha Assembly Solutions, a MacDermid Performance Solutions Business, will present two topics at the workshop. The first topic, "Thermal and Optical Characterization of LED Die Attach Materials", will focus on the effects of using die attach materials in high-power LEDs.

High-power LEDs generate significant heat, that if not efficiently removed from the assembly, leads to lower luminous flux and lower operating efficiency. As most of the heat is transported through the die attach layer, the thermal resistance of the heat path significantly impacts the overall device performance. Higher thermal conductivity die attach materials significantly decrease the thermal resistance of an LED stack. The presentation will show the results of a laboratory study carried out by Alpha showing the comparative performance of identical LEDs assembled with a variety of die attach materials.

The second topic, "LED Assembly on Flexible Substrates", will provide an insight into the world of LEDs on flexible circuits. The presentation will cover end-applications and drivers for LEDs on flex substrates. These include solder alloys and substrate material selection, details of low to mid temperature alloys and interconnects and both polyimide and PET based substrates. Additionally, the impact and performance of typical solder/substrate material stacks in the form of applications and the evolution of flexible circuitry in new formable factors will be discussed.
