Thermal management is central to power semiconductor design, where efficient thermal structure design and material selection directly impact product competitiveness.Analyzing the fundamental nature of heat in power semiconductors at the atomic and electronic levels reveals that beyond material properties, the “bonding” process plays a critical role.The structure of a typical power module is as follows: During operation, the chip generates significant heat, which is sequentially transferred through sintered silver and the DBC substrate to the baseplate. From there, it is conducted to the heat sink via thermal grease. Each material along this thermal path directly impacts the overall heat dissipation performance. While the market offers an extensive array of material options, experimentally ...

The rapid expansion of rooftop photovoltaic systems has reshaped how solar assets are deployed and maintained. Unlike ground-mounted installations, rooftop systems face tighter spatial constraints, complex access conditions, and higher safety requirements. These challenges have driven the emergence of the rooftop solar panel cleaning robot as a purpose-built solution that combines automation, precision, and operational reliability.Rather than treating cleaning as a peripheral task, modern rooftop PV operators increasingly view automated cleaning as an integral component of long-term performance management. This shift reflects a deeper understanding of how cleanliness, system efficiency, and lifecycle costs are closely interconnected. In this blog post, WANLV, as high performance autom...
