If the bus bar is fixed to the printed circuit board, then thermal conductivity is improved, but the structure becomes more complex
Solution Approach 1:
The bus bar is permanently fixed to the printed circuit board through direct attachment methods, merging two separate components into an integrated assembly. This integration improves thermal conductivity by creating direct thermal pathways between the bus bar and the PCB, while the permanent fixation eliminates the need for separate mounting hardware or assembly steps, actually reducing overall structural complexity
Solution Approach 2:
The bus bar is divided into sections that are fixed at different locations on the printed circuit board. This segmentation allows thermal management to be distributed across multiple attachment points, improving overall thermal conductivity without requiring a single complex thermal interface. Each section can be independently fixed using simple attachment methods
