TPSM82821: Allowable number of reflow and bottom side mounting

Part Number: TPSM82821

Hi team,

The allowable number of reflow for this module device is 3 times, right?

I read below white paper and I think the FAQ's answer can be applied to this device as well.

I also read below apprication note. Could you provide the MASS, MASS/A and MASS/P value for this device?

My customer need the valut to clalify if this device can be mounted on bottom side of the PCB.

And, could you 

Best Regards,

  • Hi Atsushi,

    Yes the module should be able to handle 3 reflows. The mass of the module is 11.1289 mg. The size of each pad is 0.25mm × 0.65mm. You can consider the area as total pad area (8 pads ×  0.25mm × 0.65mm) and the perimeter as (8 pads × 2 × (0.25mm + 0.65mm)). It shouldn't be a problem to mount it on the bottom of the PCB.

    Best regards,
