Hot Spot
Hot Spot refers to a localized area on the PCB that experiences a significant temperature rise during operation. This can lead to several potential problems:
Component Damage: Excessive heat can damage electronic components, reducing their lifespan or causing premature failure.
Solder Joint Degradation: High temperatures can weaken solder joints, potentially leading to electrical connection issues.
Warpage or Delamination: In extreme cases, heat can cause the PCB to warp or delaminate (layers separating).
Use thermal imaging cameras to find hot spots on the PCBA. Carefully placed components, proper power management, and heat sink design can prevent them. Thermal vias also help dissipate heat by transferring it to outer layers.
