I'd guess that "black pad" is not the issue that you need to address, because only 2 of your 5 test points has the problem that we seem to be discussing. I'd expect "black pad" problems to be more wide spread. Something is going on at those two locat

From the pic, it looks like you have a bad board; ENIG process issue. It used to be called black pad for SMT but I'm sure it's the same condition for T/H. Any good electronic lab should be able to id the black stuff. I would also send raw boards bac

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.
