OPTIMUM PALLADIUM CONTENT IN ENEPIG SURFACE TREATMENT FOR ENHANCING MECHANICAL PROPERTIES

摘要

The present invention relates to a change in the reliability according to the palladium content in the ENEPIG surface treatment , more specifically relates to an optimal surface ENEPIG palladium content during the process . According to the present invention , the content of the palladium by weight exhibited the highest reliability when compared to 0.04wt% or less of the solder ball . ;
