WebPd thickness (um) Au thickness (um) Pd provides an excellent barrier to Ni migration through the Au 15 minutes in the Pd bath typically provides 0.2um of Pd. Wire bonding strength for ENEPIG is higher than ENIG even with thin Pd thickness range. Au thickness increase shows improvement in wire bond strength while Pd thickness increase does not. Web1 nov. 2000 · As mentioned previously, the use of 325 to 400 mesh screens achieved a fired film thickness of 5 to 8 µm for the spherical gold conductor paste. This result is due primarily to the tighter packing density achieved from the spherical powder size.
