For harsh environments you can get an exemption from the ROHS directive.
It is possible to reball to leaded balls, but it is very expensive.
We have an exemption from the RoHS directive, and I know that we can reball,and I know that it is expensive.
What I do not know is if NXP can deliver any iMX6 processors in leaded BGAs.
So I repeat the question:
Hello Ulf Samuelsson,
Reballing the BGA’s yourself may be the more plausible option as there are no leaded i.MX part numbers being produced. You could always contact NXP sales to see if it would be possible to get a custom part, but it would depend a lot on whether the leaded processes are still available and the volume of parts you need.
I’ve heard of cases in which leaded flux is applied to the BGA but it’s not the ideal scenario in terms of mechanical reliability and it would require to be careful as the footprint wouldn’t be planned to accommodate the extra flux.
My apologies for the inconvenience!
