    摘要: Methods and systems to method to determine an adhesion force of an underfill material to a chip assembled in a flip-chip module are provided. A method includes forming a flip-chip module including a chip connected to a substrate with a layer of underfill material adhered to the chip and the substrate. The method also includes forming a block from the layer of underfill material. The method further includes measuring a force required to shear the block from a surface of the flip-chip module.

    摘要: Utilizing an appropriately configured laser interferometer, the warpage of a silicon chip can be easily monitored during the solder reflow attachment process in an effort to determine the amount of stress encountered by the chip. Warpage measurements can then be continuously monitored throughout the process and related data can be stored to easily suggest the level of warpage generated by various processing parameters. By dynamically monitoring warpage in conjunction with processing parameters, a correlation can be established between the various parameters chosen, and resulting warpage. Based upon this correlation, the evaluators can easily identify those parameters which produce minimum stress, thus avoiding potential for breakage and damage during reflow operations.
