Why not mixed process (Backward SnPb) ?
-----Message d'origine-----
De : TechNet [mailto:[log in to unmask]] De la part de Bob Landman

Objet : [TN] Interposer for SAC BGA
I have to use a new FPGA from Lattice and they are not offering it in SnPb,
only SAC balls. This is a fpBGA 23mm sq with 484 balls in a square array
with no special heatsink pads.
Environment is -40 to +85C, mild vibration and shock, outside environment in
electrical NEMA enclosures.
SnPb is a must - I refuse to use lead free process for our products.
Two choices:
Interposer board (Bill Rollins just told me about this option
Reballing
Comments please on your preference.
Bob Landman
