发明名称 Method and apparatus for reducing stresses applied to bonded interconnects between substrates
摘要 A method (200) is provided for reducing stresses applied to one or more bonded interconnects (106) of a substrate (103) and a PCB (Printed Circuit Board) (104). The method comprises the steps of coupling (204) a compound (108) on a top surface of the substrate, wherein the compound has the property of expanding when a heat profile is applied thereto, coupling (206) a cover (102) to the PCB that overhangs at least a portion of the compound, and applying (208) the heat profile to the compound and optionally the cover and/or PCB. More than one apparatus implementing the method is also included.
