LYON, France – December 14, 2016: In 2015, all economic indicators pointed to continued market growth for both industries, power electronics and LED , especially with IGBT modules boosted by EV/HEV industry and general lighting applications, a killer application for LEDs since 2012 . To support this growth and answer the thermal management needs in power electronics and LED, lot of innovative technologies are emerging. According to Yole Développement (Yole), one of the most impressive technical developments is the convergence of thermal management for both sectors, LED and power electronics, particularly the materials used for thermal management. The thermal management convergence is driven by the applications, announces the “More than Moore” market research and strategy consulting company, Yole.

Thermal Management Technology & Market perspectives in Power Electronics and LEDs report
powered by Yole’s Power Electronics & LED teams, reviews insight into synergies between power electronics and LED for thermal management. It describes and analyzes drivers and challenges that are facing industrial companies. This latest report proposes an overview of the market trends and technology evolution including 2015-2021 market figures, technology status and technical roadmap analysis and more. Under this report, Yole’s analysts also offer business model and supply chain analysis across various materials used for thermal management.
A rapid convergence of key technologies is driving unprecedented change. In this dynamic environment, Yole’s goal is to understand their customers’ strengths and guide their success.

“Power electronics and LEDs are different industries that today face similar challenges”, explains Dr Pierric Gueguen, Business Unit Manager at Yole. And he adds:”Needs for green energy with lower CO2 emissions have led these industries to develop more efficient and smaller solutions.” At the device level, cost pressure and the need for better performance is pushing designers towards smaller and thinner chips, also leading to increased power density. Such power density targets in both power electronics and LEDs bring a convergence of thermal management requirements, supporting the development of new materials.

Among materials used for thermal management, Yole specifically investigated the market and technology evolution of die attach, substrates, baseplates/PCBs and encapsulants. Overall, the market for these materials was worth US$1.98 billion in 2015 and will grow to US$3.16 billion by 2021 at a CAGR of 6%.
“Their value proposition has the potential to bring business to their suppliers and key differentiating factors to device manufacturers”, comments Pierrick Boulay, Technology & Market Analyst at Yole.

“Power electronic modules represent a healthy market, worth about US$2.9 billion in 2015 and set to reach US$4.5 billion in 2021, growing at 9% CAGR”, explains Pierric Gueguen. In parallel, the LED packaging market reached US$15 billion in 2015, after years of strong growth led by LED TV and general lighting. However, price pressure will moderate growth in coming years, with a 3.4% CAGR leading to a market worth US$18.5 billion in 2021.

Power electronics and LEDs need the right materials to handle thermal management challenges. As those applications are driven by similar technical requirements, one technical solution can be adopted and developed for one industry before being used by another industry. “The 30% of the overall thermal management material market that is common to both LED and power electronics represents US$660 million in 2015”, announces Pierrick Boulay. “According to our estimations, such market segment will reach US$1014 million in 2021”. Moreover, another 30% can be reached by adapting existing technologies used in LED or power for the other application…

From perspectives ranging from manufacturers and material suppliers through to end users, market dynamics, drivers and challenges are presented in this report, for both power electronics and LEDs.
