S32K116 thermal loading

[aihua_wang1]

How to do the thermal loading and junction calculation for S32K116 48 pins? The thermal resistance from junction to board is 33C/W. but there isnot specify which pin? or is there a metal base that soldered to the Pcb? do we have the solder recommendation information?

Thanks.

Hello,

Please, refer to the AN4388

https://www.nxp.com/docs/en/application-note/AN4388.pdf 

The application note provides guidelines for the handling and board mounting of NXP's QFP packages including recommendations for printed-circuit board (PCB) design, board mounting, and rework.

I hope it helps.

Best regards,

Diana
