Points on Parts

Hello Patrick, Thank you for posting.

Please provide a TI part number of a device in question, so the question may be routed to the correct team.

Hello Ed,

this is not a part from TI, its from a other vendor. I thought someone here could explain this to me.

Hello Patrick,

Since it is not a TI device we are not able to comment on the question.

Hello Ed,

now i have some TI Parts here with this points what i mean.

I hope you could explain this. It looks not normal.

Hello Patrick.

We need the device part numbers of the IC's in question so your post can be routed to the correct product group.

This is the Part Number:

TPS65910A3A1RSLR

Hi Patrick,

My initial assumption is that these are indentations from the test socket when the device was screened before shipping. Depending on the type of socket, the pressure from the contacts could leave small marks on the solder pads.

Best Regards,

Hello Rick,

thanks for your answer. But is it normal, that this small marks are on allmost every part of 500 pcs ?

Best Regards,

Hi Patrick,

The individual components of the socket and the IC packaging all have tolerances that could result in these indentations. These should not affect the performance or the solder-ability of the IC.

If any device is found to be defective, your local TI sales office can pursue a failure analysis report for further assurance.

Best Regards,

Rick S.
