| Abstract: | The influence of temperature variation on the energy transfer efficiency of the wafer, (apparatus) performance and coupling effect were studied qualitatively and quantitatively by (experiments). Then the effect of these influences on the reliability of the results obtained by ultrasonic inspection, including the location and size of the defects, are analysed. According to the results (obtained) above, methods of conpensation adjustment, (environmental) rectification and localized heating are proposed to improve the inspection. Also the (advantage) and disadvantage of these methods and their applicability are compared. |
