Abstract

Purpose

To present a simple way of assessing blind vias, making failure analysis easier to perform and generating less controversy.

Design/methodology/approach

The paper describes a procedure that may be used to examine blind via hole interconnections for routine testing or during failure analysis of a printed circuit board.

Findings

The technique described complements existing methods for assessing vias.

Originality/value

The paper details a new method of via assessment that can be an alternative to established techniques.
