Hi , Could you be seeing the nickel under the gold plating because you are removing some of the Gold with the Kapton Tape....?? You mean , the adhesive properties of the kapton tape will cause the gold plating on the gold finger to be somehow peel of

>>> gold finger was covered by a Kapton tape and it was done offline away from the Screen printer or rather from the SMT lines itself, we are using an ENIG Pcb's , the process doesnt need a wave soldering ....however at the final end of the line ,

A problem exists with electroless nickel / immersion gold (ENIG) surface finish on some pads, on some boards, that causes the solder joint to separate from the nickel surface, causing an open. The solder has wet and dissolved the gold. A weak tin to nickel intermetallic bond initially occurs, but the intermetallic bond cracks and separates when put under stress. Since the electroless nickel / immersion gold finish performs satisfactory in most applications, there had to be some area within the current chemistry process window that was satisfactory. The problem has been described as a 'BGA Black Pad Problem' or by HP as an 'Interfacial Fracture of BGA Packages…'[1]. A 24 variable experiment using three different chemistries was conducted during the ITRI (Interconnect Technology Research Institute) ENIG Project, Round 1, to investigate what process parameters of the chemical matrix were potentially satisfactory to use and which process parameters of the chemical matrix need to be avoided. The ITRI ENIG Project has completed Round 1 of testing and is now in the process of Round 2 TV (Test Vehicle) build.
