Q: Page 61. There shouldn’t be two columns for Rjc in the table, since this parameter does not depend on the board conductivity.

A: 

Actually, there is a mistake in the table concerning the active components cases: therefore, only six columns should be displayed in the page 61 table (case type, equivalent name, Np, Rjc, Rja with V=0m/s – Low conductivity and Rja with V=0m/s – High conductivity). Rjc “high conductivity” should never be used.
