    gold plating, and autocatalytic type electroless gold plating. Firstly, we investigated the relationship between wire bondability and the electroless gold film thickness. A 5 μmthick electroless nickel film and a 0.05 μmthick electroless palladium film were plated, and subsequently, electroless gold films of 0.05 to 0.2 μm were plated. After

    The difficulty of an electroless nickel / immersion gold process is in its complexity. The multiple pretreatment steps, plating steps and process control levers to consider are the reason why ENIG has been a historically difficult process to handle. Affinity ENIG 2.0 was developed using process control methodology and the result is a more
