LP2985A: Lead finish/ Ball material use in reflow oven

Jan Bock

Part Number: LP2985A

My customer is looking for an alternative to LP2985AIM5X-3.3/NOPB
Due to delivery problems, alternatives are currently being examined and they
released the following designations:
LP2985A-33DBVR
LP2985A-33DBVT
LP2985AIM5-3.

There is also the version LP2985A-33DBVRG4 (NIPDAU without |SN). In contrast to LP2985A-33DBVR this one is not tinned, right?
The component has to go into our reflow oven and the lack of tinning can cause problems here.
Can TI make a statement about whether the application in the reflow oven affects the functionality?
Is there any information from TI on this subject whether processing is possible or there may be technical problems with the component.

Regards

Hi Jan,

You are right about some of the devices are with NIPDAU and some of them are NIPDAU+SN and I have confirmed this information from our orderable table you can find at the bottom of the datasheet.

We generally don't make a recommendation on the reflow process as this will be better answered by the manufacturers but let me consult our quality engineer to see whether they may have some inputs. It may take 2-3 business days for them to respond and I will post an update here when it becomes available.

Regards,
Jason Song

Hi Jan,

Have you got a chance to check with the assembly company? I am sorry but we may not be able to provide you a recommendation/statement on the reflow oven with untinned units.

I am still trying to talk with different people that may be familiar with this matter, in case, I get any update, I will let you know.

Regards,

Jason
