Where would I find studies on small hole (.006"-.010" mechanical drill) via plating reliability?

Plating reliability tends to be a function of hole size only with the respect to aspect ratio (board thickness/hole diameter). See IPC TR-579 for reliability predictions. However, you seem to be suggesting concerns with hole quality? Please feel free to contact me directly to help resolve your question.
