網頁As a result of the temperature increase, a layer of said second metal is selectively provided at the die pad area of the leadframe by a galvanic displacement reaction. An oxidation of the outer layer of the leadframe is then performed to provide an enhancing layer which counters device package delamination. 網頁2013年1月1日 · For the high carbon steel, however, the scale was essentially a two-layered because of the low proportion of hematite (Fe 2 O 3) formed. The scale thickness increased with the temperature and time of oxidation. The rate of scale thickening rapidly increased above 900 °C, at which the rate was particularly fast in the first 20 s of oxidation.
