Q: Page 60. The FIDES Guide defines the "high conductivity" and "low conductivity" of a board. However, the table displaying parameter K values shows "low conductivity" and "unknown conductivity".

A: 

Concerning the table, it should only display "high conductivity" and "low conductivity". Therefore, "conductivity unknown" should be replaced with "high conductivity". Furthermore, if the thermal conductivity of the board is unknown, it is recommended to choose a high conductivity.
