Large excess resistance noise has been observed in small conductors surrounded by air. The conductor resistance was found to have a well-defined average power spectral density over the observed frequency range from 10-4 to 200 Hz and the dependence o

A commercial anisotropic conductive film (ACF) was used to form electrical interconnections between the aluminum metallization on a silicon wafer and tin plated copper pads on a polyimide flexible circuit. Some samples were subjected to temperature/h

The standard model for electrical resistance of an anisotropic conducting film (ACF) bond has been analyzed for the case that includes both constriction resistance and a film resistance between the conducting particle and the bond pad. The electrical

The observed development of flicker with time in active matrix liquid crystal display (AMLCD) panels has been correlated to the threshold voltage shift of the thin film transistors (TFTs) used in panels. The effect of a threshold voltage shift on the

The channel capacity of a parallel bus structure was examined in relation to the ever increasing demand for signal input and output. The limitations on signal integrity caused by both far-end and near-end crosstalk noise were considered. Expressions

The approach, represented by this work, makes a quantitative study of volume removal as well as of the impact wear mechanism in electrical connectors, taking place under a moderate electrical current. Comparison is made between pure mechanical wear a

High resolution electrical resistance measurements were used to monitor interconnection failures on PCMCIA test cards. The cards were clamped at the connector end by a fixture which was attached to a shaker. The shaker was excited at the card's first
