Technic has announced the release of Technic EN AT5600, an electroless nickel developed specifically to eliminate black pad and to improve soldering on ENIG coated PCBs. Technic EN AT 5600 is the first electroless nickel that provides lateral growth on copper, yielding a flatter surface with less pronounced grain boundaries instead of the typical nodular, "cauliflower-like" structure from older formulas.

The 4-14 IPC Standards Committee recently created a revision to the IPC4552 specification for Electroless Nickel/Immersion Gold (ENIG) finished Printed Circuit Boards (PCB). Revision A brings a more comprehensive evaluation of metal layer thicknesses measurement, composition and introduces, for the first time, a quality aspect for nickel corrosion which has been historically connected to a defect called black line nickel or black pad.

The use of an electroless nickel, immersion gold (ENIG) surface finish comes with the inherent potential risk of Black Pad failures that can cause fracture embrittlement at the interface between the solder and the metal pad. As yet, there is no conclusive agreed solution to effectively eliminate Black Pad failures. The case studies presented are intended to add to the understanding of the Black Pad failure mechanism and to identify both the plating and the subsequent assembly processes and conditions that can help to prevent the likelihood of Black Pad occurring.
