Description
Summary:Generally, reliability concerns of LED lighting system were focused on the degradation of GaN LED chips. But in actual applications, some other types of degradation are occasionally reported. One of the major reliability issues is sulfur originated corrosion of lead frame. Influence by corrosion, mechanism of corrosion, corrosive tendency and methodology to evaluate quantitative corrosion was considered during the study.
