TPS23755: Metal under solder mask Y dimension

Michael Balourdas

Part Number: TPS23755

Hello,

On page 42 of the TPS23755 datasheet, the X dimension of the dotted line (metal under solder mask) is shown as 2mm. I don't see a number for the Y dimension, is it 6.4mm (5.5+.45+.45)? I'm not sure if the 0.45mm marking goes all the way to the bottom of the dotted line.

Thanks,

Michael

Hello Michael,

Yes I believe that is correct. I can also send you the Altium file if you want to use it?

Hi Michael,

It looks like there is some additional space between the green line and blue dotted line that isn't accounted for by the 0.45mm measurement:

But it just says "0.05mm MIN". Is there any way to determine what the actual distance is of that buffer on the Y dimension of the dotted blue rectangle?

Thanks,

Michael

Hi Michael,

Michael is currently working with the packaging team to get their guidance on these measurements. Given the weekend this will be answered next week. Thanks!
