experiments in this study were performed on an OSP finished board. Finishes such as OSP which do not have a nickel later represent the worst case scenario with respect to Cu dissolution. An OEM server product was used as the test vehicle throughout this study

. Recommended for ENIG finish In ENIG finish, Sn-Ni IMC layer thickens and along with concentration of P causes the joint interface brittle.By adding Ni-compatible Cu, SB6NX forms a Ni barrier layer and effectively prevents the thickening of Sn-Ni IMC layer, realizing high joint reliability with ENIG finish
