Corrosion Resistance of Automotive PCBs
If you are in the automotive electronics industry, attached is a detailed read on corrosion resistance of PCB surface finishes. Atotech employees from Germany, USA and China subjected automotive market PCB’s to corrosion tests such as salt-fog. Turns out tin immersion finish offered the best overall corrosion protection. Cascade TEK performs corrosion resistance testing it all forms: salt-fog, cyclic corrosion, immersion, sand/dust bombardment, chemical splash to name a few.
