Are the coupons scaled the same as the images? Are you sure?
Is it a sequential lamination?
If the drill is scaled (even from the center) it still has to be
positioned
relative to the innerlayer images correctly. How is this done? Are you
using
a drill  optimizer (Smart Drill, Pluritec or the like)? If so, where are
the
optimizer targets?

Subject: Registration problem


Hello Technetters,

Lately I have been having this problem with some rigid-flex panels:

X-ray after drill shows good registration on coupons (which are located
at each corner and along the edges) but bad registration inside the
panels (from small annular rings to breakouts).
* Everything on a layer is scaled from the center of the layer.
* Layer to layer registration is good.  Inside the panel, however,
registration is good on the lower left corner but starts getting bad
towards the right and top of the panel making it look like drill is
scaled from the lower left corner.  Drill operator confirms that drill
is scaled from the center not the corner.

I can't explain how this problem happened and would appreciate any help.

Thank you in advance.

Tuan Le
