For decades, the electronics industry depended on gold for wire bonding. The metal’s softness and oxidation resistance made it easy to manipulate, and very fine bonds could be made without cracking or damaging boards. Temperature cycling was never a major concern – a boon for automotive applications routinely exposed to harsh environments.
The automotive industry is rapidly changing. A number of technologies are either currently available or in development that are aimed specifically at improving vehicular safety. Along with these welcome – and needed – advancements comes much stronger regulatory oversight incorporated into ISO-26262.
The automotive industry is one of increasing technological advancements. The vehicular electronic content on a typical internal combustion engine currently hovers between 70 and 80 modules. Factor in the complexities of hybrid and electric vehicles and the number rises exponentially. These complexities add to OEMs’ comprehensive safety testing that encompasses item definition, safety life cycle initiation, hazard analysis and risk assessment, and functional safety concept.
