Webstrates. The metallization pad of the bismaleimide triazine (BT) substrates were 0.025 m Au/5 m Ni–P/20 m Cu. Again, the solder pastes were printed and deposited on the metallization surface of the BT substrates. The substrates were also reflowed at the peak temperature of 210, 250, 250, and 280 °C for the SnPb, WebA systematic investigation of mechanical testing was conducted to correlate the brittle fracture observed in Ni(P) metallization with Ni-Sn intermetallic spalling in Pb-free solder joints. To produce lap shear test samples, two FR4 PCBs finished with Ni(P)/Au were reflowed using two Pb- free solders, Sn-3.5Ag and Sn-3.0Ag-0.5Cu (in wt.%).
