PCB Circuit Board Salt Fog Chamber can determine the corrosion resistance of iron metal or the iron metal inorganic film or organic film test, such as: electroplating, anode processing, conversion coating, painting, ect.
PCB Circuit Board Salt Fog Chamber is an accelerated corrosion test that produces a corrosive attack to the coated samples in order to predict its suitability in use as a protective finish. The appearance of corrosion products (oxides) is evaluated after a period of time. Test duration depends on the corrosion resistance of the coating; the more corrosion resistant the coating is, the longer the period in testing without showing signs of corrosion. Different coatings have different behaviour in salt spray test and consequently, test duration will differ from one type of coating to another.
