Whisker generation factors and prevention methods from connector

Abstract

We variousuly examine the genelation factor of whisker by the engagement of the connector according to lead free plating use,and report on the result of exmining the whisker prevention methods.As a result,thin plating Sn of FFC found the generation of whisker after the reflow being suppressed in the combination of the connector and FFC.Moreover,the intention to improvement Sn plating is preferable in the future though the Au plating is recommennded nou in the combination with FPC.The simple examination method was examined along with the above-mentioned content.
