Saltúðaprófunarklefi) is a common and destructive atmospheric corrosion, especially for PCB boards used in marine and saline-alkali environments, the verification of salt spray corrosion is particularly important.
1. Matsaðferð
After the salt spray test of the three anti-paint of the PCB board is completed, the salt crystals on the surface of the PCB board are washed with flowing water, and the corrosion degree of the product surface is carefully observed with the naked eye in a well-lit environment.(Salt Mist Test Chamber)
2. Appearance inspection
A layer of white salt crystals will be precipitated on the surface of the three-proof paint of the PCB board after the salt spray test, and it will disappear naturally after washing with water.
Á þessum tíma skaltu fylgjast vel með og bera það saman við staðlaða sýnishornið. Ef málningarfilman á yfirborði PCB borðsins er slétt og flöt, engin skemmd, hrukkum og öðrum yfirborðsgöllum, er hægt að dæma vöruna hæfa.(Salt Mist Test Chamber)
