Hello people,

 

 

I am interested in designing a cooler for OPI Zero and OPI LIte.

 

Next is the formula of calculus:

I am NOT able  to find next parameters:

T_Jmax = this is the DIE(microprocessor) wanted temperature ---> is this 30-40 degrees best temperature for OPI for well functioning in parameters?

P_DMAX = power that is generated by the losses of OPI Zero board and OPI Lite board.

Q_jc = thermal resistance between DIE(microcontroller) and case 

 

Can please someone help? 

 

Thanks.
