WebThe effect of the oxidation of Cu-base leadframe on the interface adhesion between Cu metal and epoxy molding compound Abstract: Low temperature oxidation of a Cu-base leadframe has been made to investigate the effect of Cu oxidation on the adhesion of Cu-base leadframe (Cu L/F) to epoxy molding compounds (EMC).
Web1 apr. 2011 · After the four types of copper leadframes oxidized at the 300 °C for 5 min, the oxide thickness are measured using cathodic reduction method. The oxide thicknesses at different temperature are show in Fig. 3. It is found that the oxide thickness is thinner for samples with trace Ag than bare copper in both dry and hygrothermal conditions. Web1 mei 2003 · A copper leadframe is chemically active and will oxidize if exposed to air, but this oxide species is not mobile. On the other hand, copper sulfide and chloride have significantly higher surface mobility than copper oxides [10], [11], and can significantly accelerate and regenerate the copper corrosion products.
