Heavens to Murgatroyd, we agree with Russ that "black pad" could be the cause of your solderability problem, but oxidized nickel is an additional explanation. While its often easy for assembler to jump this conclusion, it sounds like you've been bla

the flux in the solder paste should take care of the oxides. if possible print a board and run thru reflow to check for wetting issues......there are some published papers that say that the tarnish layer is too small to create any wetting issues or o
