Is it possible to get an acceptable solder joint if a Pb free BGA is put onto a board using SnPb solder paste and normal SnPb
profiles?
The lead free solder balls are SnAgCu 96.5/3/0.5.
Seems nigh impossible to get DDR2 packages with SnPb balls.
I'm designing a high end DSP into an industrial instrument. The DSP is not available lead free, nor does the application call
for lead free (thankfully).
There is no option to use a different memory type with the DSP. Nor is there any possibility of using a different DSP or FPGA
due to time/cost/sanity.
Don't want to explore going lead free on this one (for obvious reasons), and certainly do not welcome the expense of reballing
0.8mm DDR2 chips.
Best Regards
David Greig
