Subject: Re: [TN] Local Fiducials

We use local fiducials frequently with all fine pitch, especially .4mm BGA's. If problems arise, that is one variable eliminated.

Subject: [TN] Local Fiducials

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.
