Witryna20 gru 2024 · A new multilayer metallization, electroless-nickel electroless-palladium immersion gold (ENEPIG) with a thin 0.1-μm-thick Ni(P) layer (thin-ENEPIG), was plated onto a Cu printed circuit board substrate for fine-pitch package applications. We evaluated the interfacial reactions and mechanical strengths of Sn–3.0Ag–0.5Cu … WitrynaThe beneficial role of Zn on immersion Ag pads was ascribed to the formation of Ag-Zn IMC layers, which were fairly resistant to the drop impact, and to the suppression of the brittle Cu 6 Sn 5 phase at the joint interface. The solder joint microstructures of immersion Ag with Sn- xZn ( x = 0 wt.%, 1 wt.%, 5 wt.%, and 9 wt.%) solders were ...
Witryna1 lip 2010 · The solder joint microstructures of immersion Ag with Sn-xZn (x = 0 wt.%, 1 wt.%, 5 wt.%, and 9 wt.%) solders were analyzed and correlated with their drop impact reliability. Addition of 1 wt.% Zn to Sn did not change the interface microstructure and was only marginally effective. In comparison, the addition of 5 wt.% or 9 wt.% Zn … Witryna29 lip 2024 · This paper investigates the growth behavior, morphology of intermetallic compound (IMC) layer and hardness of low melting temperature Sn–35Bi–1Ag (wt%) solders on different surface-finished Cu substrates i.e., immersion Ag (ImAg)-plated Cu and Ag/Ni-plated Cu substrates. From SEM observation, a scallop-shaped Cu6Sn5 …
