Abstract

Purpose – Tracks, pads and vias on printed circuit boards can suffer from a variety of problems, if the surfaces are contaminated with electricallyconducting substances. Aims to model a multilevel full-factorial design to study the effects of temperature, voltage and electrode gap on dendritic growth under saturated conditions, i.e. water droplet contamination. Design/methodology/approach – Preparation of several DC-biased combed-copper interdigitated capacitors placed in temperature-controlled water-filled cuvettes enabled the specific monitoring of dendrite activity. The monitoring used the detection of sharp current increase that accompany a dendritic short circuit condition. Findings – A high R2 polynomial model was produced and it was noted that increased voltages reduce the reliability impact of dendritic growth. Originality/value – The paper focuses on the reliability impact dendritic growth in saturated conditions.
