Dear TechNet,

   What kind of alignment systems are available for laying up multilayer
flex circuits just before consolidation?  I have been "hand" aligning my
patterns and sometimes use a pinning bar, but with layer count increasing,
this is becoming more difficult.  I get better results with hand aligning,
versus using a pinning bar.  However, when I use the pinning bar, only one
side of the films are pinned, perhaps I need to have at least two or more
sides pinned to ensure alignment.  Any thoughts on this anyone?

                                Thanks,
                                Nancy
