Abstract:
1. A method for use in analyzing an underfill material dispensed onto at least a first and a second supporting substrate, the method comprising: dispensing the underfill material in a dispensing system onto the first supporting substrate adjacent to a first packaged microelectronic device attached to the first supporting substrate; after the underfill material is dispensed, transferring the first supporting substrate, the first packaged microelectronic device, and the underfill material as an assembly from the dispensing system to an automated optical inspection system; capturing an image of the material using the automated optical inspection system; analyzing the image using an image-processing computer to determine one or more dimensions of a fillet formed by the underfill material at a peripheral edge or a corner of the packaged microelectronic device; comparing the one or more dimensions of the fillet with a dimensional standard to determine whether the fillet is properly dimensioned; communicating the one or more dimensions of the fillet from the automated optical inspection system to the dispensing system; automatically adjusting an operating parameter of the dispensing system based upon the one or more dimensions of the fillet; and dispensing the underfill material in the dispensing system onto the second supporting substrate adjacent to a second packaged microelectronic device attached to the second supporting substrate based on the adjusted operating parameter.
