PCB Creepage rules in ElectroCool dielectric fluids
The IPC-2221B specification provides creapage and clearance guidelines of components and conductors of PCB in free air. In a completely submerged application, can the spacing be smaller? Is there general guidelines on required distances for High Voltage applications with your dielectric fluids?

Yes, in immersion cooling, clearances between components can be smaller than they would be in air cooling. That being said, there are no guidelines (yet) on how much distance or clearance should be between them. For high voltage applications, clearances should be guided by the dielectric strength of the insulating fluid, which in the case of ElectroCool coolants, is >60KV with a 2mm electrode gap.
