    摘要: A method and apparatus for dispensing a volume of die attach adhesive onto a surface can include an optical system which images the dispensed volume of die attach adhesive. A two-dimensional area covered by the die attach adhesive and a die attach dispense pressure can be used as a comparison with a reference value to determine whether the volume of die attach adhesive dispensed is sufficient. The reference value can take into account viscosity changes of the die attach adhesive, so that the volume of die attach adhesive dispensed during production can be determined. The volume dispensed can be automatically adjusted in situ during production using a computer system.
