20090298206 | METHOD AND APPARATUS TO MINIMIZE STRESS DURING REFLOW PROCESS - 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. | 12-03-2009 |
