Performing Flux-Technology for Pb-Free SN100C Solders

SN100C (Sn99Cu0.7 with Ni- and Ge-micro-additions) is a lead-free solder alloy that is finding increased acceptance globally and holds promise as a mainstream solution in terms of long-term sol .. read more

The Effect of Plating Cell Configuration on the Quality of Copper Deposit for Printed Circuit Boards

This paper addresses the effect of pulse plating of electronic interconnects for advanced electronic modules. This paper builds on earlier work by correlating plating cell and tank design issue .. read more

Recrystallization Principles Applied to Whisker Growth in Tin

Tin whiskers found in electroplated deposits are known to be single crystals which spontaneously grow. Thus whisker growth can be regarded as a grain growth phenomenon. In this paper we examine .. read more

Formation and Growth of Intermetallics at the Interface between Lead-free Solders and Copper Substrates

Intermetallic formation and growth were studied for the alloys Sn-3.2Ag-0.8Cu,Sn-3.5Ag,Sn-0.7Cu,and Sn-9Zn. Coupons of solder joints (prepared by melting some of each solder alloy on a copper-p .. read more
