Abstract: One consideration of PCB final finish selection is the susceptibility to creep corrosion in environments containing atmospheric sulfur. In this study several PCB final finishes were subjected to a Battelle Class III mixed flow gas test to assess creep corrosion susceptibility. The PCB finish coatings tested were 1) Pb-free HASL, 2) direct palladium, 3) immersion silver, 4) OSP, 5) ENIG and 6) ENIPEG. The assessment method was an end-point visual examination focusing on the extent of creep corrosion products.
