Alpha to Present on LED Products at Lighting Technology Show
September 26, 2017 | Alpha Assembly SolutionsEstimated 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.

06/26/2025 | Team NCAB -- Column: Fresh PCB ConceptsMicro components have redefined what is possible in PCB design. With package sizes like 01005 and 0201 becoming more common in high-density layouts, designers are now expected to pack more performance into smaller spaces than ever before. While these advancements support miniaturization and functionality, they introduce new assembly challenges, particularly with traditional solder mask and legend application processes.
Knocking Down the Bone Pile: Tin Whisker Mitigation in Aerospace Applications, Part 3
06/25/2025 | Nash Bell -- Column: Knocking Down the Bone PileTin whiskers are slender, hair-like metallic growths that can develop on the surface of tin-plated electronic components. Typically measuring a few micrometers in diameter and growing several millimeters in length, they form through an electrochemical process influenced by environmental factors such as temperature variations, mechanical or compressive stress, and the aging of solder alloys.
