Sent by:        TechNet <[log in to unmask]>



Are local fiducials (those specifically associated with a single 
fine-pitch device) necessary anymore?  I've been told by a rep from our 
Assy CM that they're not necessary anymore with the advent of high-tech 
pick and place machines.  We've actually been designing some boards with 
.4mm pitch BGA's  Does this fine of pitch still not require fiducials? 
Thanks in advance for the response.
