Thick film screen printing technology is able to reach a pitch of 250 μm. In an attempt to achieve lower values, two approaches have been developed so far. Both are based on the combination of screen printing as a deposition technique and photolitho

The solderability of a material is considered as the ability of the surface to be wetted by solder, and the rate at which this process occurs. The solderability of thick film conductors based on palladium—silver, by Pb/Sn/Ag solder, was evaluated u

The reliability of thick film multilayer systems, based on palladium‐silver conductors, and obtained from several suppliers, is evaluated. A test structure is presented and the impact of different parameters, such as humidity, temperature, voltage

A new method of studying the accelerated ageing of interconnection materials is applied to a high‐stability thick film resistor system (the Du Pont HS‐80 system). The new method, referred to hereafter as the in‐situ method, allows measurement o

The evolution of today's high speed electronic systems has resulted in the need for modules which are able to provide all chip‐to‐chip interconnection with very fine top level and buried conductor traces, and a dielectric with a very dense via gr

Silicon nitride films are currently investigated by AES combined with ion profiling techniques for their stoichiometry and oxygen content. During this analysis, ion beam and primary electron effects were observed. The effect of argon ion bombardment

In vitro cultured mouse peritoneal macrophages are inefficient host cells for both alpha and flaviruses tested. Production of infectious virus ceased 6 to 24 h after infection, except for virulent and avirulent SF strains. This limited growth is unre
