Alpha to Host Workshop at Second Annual LED A.R.T. Symposium
October 26, 2016 | Alpha Assembly SolutionsEstimated reading time: 5 minutes
Alpha Assembly Solutions, the world leader in the production of electronic soldering and bonding materials, will be hosting a workshop on LED Interconnects for Die Packaging and Luminaire Assembly during the second annual LED Assembly, Reliability & Testing Symposium organized by SMTA that will be held on November 29th in Atlanta, Georgia.
The workshop is intended to dicuss interconnects at die level (Level 1, die attach), package on board (Level 2, light engine assembly) as well luminaire level (Level 3, retrofit bulbs / tubes etc). Interconnect materials as well as thier end-use application and process methods (die attach processes, SMT assembly, soldering etc) will be discussed. Finally, optical and thermal characterization methods for LED packages (light output, color measurement etc) will be covered.
In addition, Alpha Assembly Solutions, a part of the MacDermid Performance Solutions group of businesses, has three technical paper presentations taking place during the event that will highlight findings and insights with the industry regarding the reliability assessment and qualification of LED lighting products and potential solutions.
Amit Patel, Project Manager, Engineer – LED for Alpha, will present his paper, Impact of Interconnects for LEDs on Flexible Substrates which focuses on a structured study to understand the contribution of solder alloys to overall LED-on-flex assembly reliability. LED performance was characterized at a range of operating currents by junction temperature, thermal resistance, total luminous flux, color-correlated temperature (CCT), efficacy, and wall plug efficiency.
Gyan Dutt, Technical Marketing Manager – LED for Alpha will present his paper, High Temperature Characterization of High Reliability Creep Resistant Interconnects for Outdoor Lighting Applications in which high temperature operation of outdoor high power LED systems was simulated to study the high temperature stability of lead-free solders interconnects. The solder mechanical and microstructure characterization results will be correlated with creep resistance and thermo-cycling performance of interconnects in high power ceramic LED assemblies.
Nicholas Herrick Scientist – LED for Alpha will present his paper, Thermal, Optical, and Electrical Performance of LED Die Attach Materials. High-power LEDs generate significant heat that, if not efficiently removed from the assembly, leads to lower luminous flux and lower operating efficiency. High thermal conductivity die attach materials significantly decrease the thermal resistance of an LED stack, thereby prolonging LED lifespan and increasing performance or electrical efficiency. Nicholas will present measurements of Alpha’s solder, silver-filled epoxy, and sintered silver products as used with high-power LEDs and discuss motivations behind die attach product choices for end users.
