Hi,

Does the 'trace cross section area' in line 29 come out in a wrong way? Given dw = 8 mils (line 15), dh = 35um (line 27), the 'trace cross sectional area' cannot be 5.65e-8 m^2. In fact, using Ar= dw*dw it should be 7.1e-9m^2.

Another question is on the definition of 'Turn'. According to 360/4.08 (line 22), the max turn should be 88 rather than 176. Even considering both sides of PCB, the number of traces is doubled to be 176. However, the turn number of coil still should be 88 since one top trace and one bottom together trace form one turn.

Hope to hear from you soon.

Thanks,
