. 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
