TPS717: TPS71718DCKR Internal bonding line structure

Hi Xiaoqing,

Are these devices from the same reel? It is normal to use 2 bonding wires for the same bonding pad to reduce the amount of current per bonding wire and to reduce the total parasitics, but I would not expect there to be a difference between devices from the same lot. Furthermore, these devices look like they slightly different lead frames.

Regards,

Nick

Hi Nick

These are materials from different reels, and they are products of different date codes. Will it affect use?

Hi Xiaoqing,

Can you send the shipping label for both reels? I just want to confirm the legitimacy of the parts. I don't think it will affect use as long as they are legitimate. 

Thanks,

Nick
