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
