All, We know that incomplete immersion silver could potentially lead this creeping corrosion. Is there any way to check bare PCB for incomplete immersion silver coverage, especially on the via hole area? Thanks, Sean.

Hi All, I have few questions about creeping corrosion that potentially happen on lead free immersion silver PCB as below: 1) What test that we can conducted to verify whether the failure we seen is due to creeping corrosion? 2) I heard that lead fr

Creep corrosion occurs in electronics assemblies and it is reminiscent to electromigration but does not require electrical field to drive the reaction. Corrosive elements and moisture must be present for creep corrosion to occur. Sulfur is the most prominent element to cause creep corrosion in environments such as paper mills, rubber manufacturing, mining, cement manufacturing, waste water treatment etc., also including companies and locations nearby such industries. The main part of printed circuit board assembly (PCBA) to be affected is the PCB surface finish. Especially immersion silver is prone to creep corrosion, but it sometimes occurs in NiPd (lead frames), and to a lesser extent in ENIG and OSP surface finishes. As the use of immersion silver is increasing as PCB surface finish and electronics are more and more used in harsh environments, creep corrosion is a growing risk. In this paper we will present the driving forces and mechanisms as well as suitable tests and mitigation strategies against creep corrosion
