A recent increase in wedge voiding has prompted an investigation into
the possible causes of this defect.
If anyone is experiencing this defect, (wedge voiding and/or "pink
ring") OR you DO NOT have a problem with it , I would appreciate any
information that you could supply pertaining to the following:
-Hole size defect found in and aspect ratio
-Drill supplier
-Core material supplier
-Prepreg supplier
-Oxide parameters and chemistry
Thank you in advance for your help.
