Dear TI Experts,
We've met many questions about rough Leadframe recently .Could you kindly help to give some advices about below questions? Thanks a lot.
1) the rough Leadframe started from 2018?
2) Will all TI devices change to rough Leadframe? How about the schedule?
3) Once a device change to rough Leadframe, will all the manufacture factories of TI change simultaneously? Or it may happen that rough and no-rough coexist among different manufacture factories?
I have forwarded your questions to our quality engineers. I will let you know what they reply.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Karan Kotadia:
I need to know at least business or package type to tell you when change started. I can also find out when first rough LF was used historically but I doubt it is a useful info.
Not all devices will change, some may remain un-roughened.
My understanding all factories will be capable (and maybe are already) of using both, rough and non-rough LF. Also note that rough can be different kind (both side, single side).
Thanks a lot your support. I want to double confirm one thing---- one factory may use both, rough and non-rough LF on the same device at the same time? or once one device change to rough LF, this factory will only keep the rough LF for this device? Thanks a lot.
In reply to Bruce li:
No, the device will have one kind of LF, not both. You can always ask for us to find out about a specific part.
