Comparative Study of Layout Effects on Thermal Management in PCB Hot-Plate

This paper explores thermal management strategies for PCBs with embedded heating elements, focusing on mitigating heat spread to sensitive components. The research investigates how different PCB layout modifications can contain heat and prevent it from spreading to adjacent components, which could cause damage or reduce their lifespan. The study compares the thermal performance of an unprotected board with various heat containment techniques. These include removing copper fills on internal layers beneath the heating element, optimizing the gap between the heating element and electronic components, and incorporating thermal vias to block heat transfer. Simulations show that these measures significantly improve thermal isolation, resulting in a more localized and efficient temperature distribution. The results offer actionable insights for PCB designers, emphasizing the importance of layout optimization in enhancing thermal performance. This contribution offers practical guidance for minimizing thermal propagation and protecting sensitive components in automated soldering and other high-temperature PCB applications.
