The most important corrosion terms in electronics

  • The black pad effect refers to the corrosion of Nickel in, for example: Cu/Ni/Au. Metallization of the PCB leads to black surfaces that cannot be soldered.

  • Formation of characteristic structures due to electrochemical migration processes.

  • The movement of dissolved ions in an electrical field from the anode to the cathode and the formation of dendrites, which usually causes short circuits.

  • Measurement method for the electrochemical characterization of surfaces by applying a static voltage and measuring the resulting corrosion current.

  • Standardized test for evaluating the effectiveness of corrosion protection on surfaces and coatings based on NaCl electrolytes.

  • Standardized test with mixed gases (NO2, SO2, Cl2, H2S) for the evaluation of the corrosion behavior of metallic surfaces.

  • Measurement method for the electrochemical characterization of surfaces (DIN 50918) by applying a cyclical voltage and measuring the resulting corrosion current.
