I am going to assume that the pullaway is not resin resession - I have seen this problem (which is lack of adhesion of the metal deposit to the hole wall) caused by the condition of the hole wall. If the hole wall is too smooth, almost glassy in appearance, the metallizations will plate to it but have no adhesion to it. The glassy condition was caused by either drilling or the desmear/etchback process or a combination of both SEM shots of the hole wall at the step immediately prior to metallization will tell you what you have Susan Mansilla Robisan Laboratory
