TLC7705M: TLC7705QD last LDC with Gold bond wire

Hi Yarisel, the PCN for Cu wire went out in CY2012. May I know why you're asking this question now? 

Our requirements does not allow the Cu bond wire usage but every LDC we’ve ordered so far as gold bond wires. We would like to confirm which was the last LDC with gold wire.

Hi Yarisel, I need to check with the Assembly site. Do you happen to know when you placed your last order for this device? Was it recent or from years back?

At least I have a LDC from 1836. In the PCN it looks like there is an alternative of gold wire bond. Could you confirm that too?

Thanks. What does LTC 31XXXX means?

Could you confirm that TLC7705QD with Lot Date Code 2149 has Au bond wire?

Hi Yarisel, is the 2149 from the topmark? Can you send me the Ship Trace Code STC or LTC Lot Trace Code from the Label. It will be best to check using the STC/LTC. We could have both Cu and Au wire alternate BOM at that time. 

Sure. Lot Trace Code 1CAKE5T

Hi Lorena. 

Could you confirm what change in the material declaration for TLC7705QD LDC1945 and TLC7705QD LDC2149? Or could you provide the material declaration for both?

Thanks,

Yarisel
