15% of the anomalies on the electronic boards are caused by ionic residues.<\/h2>\n

The ionic contamination of the boards themselves, even before the printed circuits that they support are contaminated, is due to a set of polluting agents that remain after the production processes of the circuit itself: generic salts, organic and inorganic acids, ethanolamines, flux activators, and chemical agents derived from the processes of metal plating, human sweat.<\/p>\n

\"contaminazione<\/p>\n

Under certain environmental or usage conditions these residues can dissolve in a water\/alcohol solution, and become conductive, thus creating defects that undermine the reliability of the board over time and cause:<\/p>\n

\u2022 Corrosion<\/strong>, that weakens the metal conductors (tracks and pads);<\/p>\n

\"\"<\/p>\n

\u2022 Formation of dendrites and loss of insulation<\/strong>, that can lead to short circuits;<\/p>\n

\"dendriti<\/p>\n

\u2022 Electrochemical migration<\/strong>, another cause of short circuits;
\n\u00a0\u2022 Electrical leakage<\/strong>, that leads to the boards not working properly<\/p>\n

In order to avoid all of this and always deliver a highly reliable printed circuit, the Alba PCB Group has adopted a specific internal procedure, which, through the use of the most recent generation of ionograph, allows a rapid evaluation of ionic contamination.
\nExamination is conducted constantly on:
\n\u2022 the productive process;
\n\u2022 the lots produced;
\n\u2022 lots produced that come from areas outside the EEC.<\/p>\n
