Report Studies
• A Submount (Heatspreader) is a crucial component in electronic and optoelectronic devices, designed to efficiently dissipate heat and enhance performance. These components are widely used in high-power laser diodes (LD), photodiodes (PD), LEDs, and other electronic applications that generate significant heat during operation.
• The Asia-Pacific region dominates the market with a 32% share, driven by rapid growth in the semiconductor, optoelectronics, and telecommunications industries, particularly in China, Japan, and South Korea. North America follows closely with 30% market share, supported by strong demand from data centers, laser-based communication, and defense applications. Europe holds a 26% share, with a focus on high-performance industrial and medical laser applications.
