Abstract:
A method of forming an electronic assembly comprising the steps of:(a) providing a substrate having a first arrangement of conductive contacts; (b) providing an electronic component having a second arrangement of conductive contacts; (c) depositing an uncured anisotropic conductive material on the first arrangement of conductive contacts; (d) positioning the electronic component on the anisotropic conductive material with each conductive contact of the first arrangement aligned with a corresponding conductive contact of the second arrangement; (e) heating the anisotropic conductive material to a curing temperature for a curing interval sufficient to cause the anisotropic conductive material to cure to a solid; and (f) during step (e), subjecting the anisotropic conductive material to an AC magnetic field followed by a static, substantially homogeneous DC magnetic field, wherein each magnetic field has a field vector direction that is substantially parallel with the alignment of each conductive contact of the first arrangement with the corresponding conductive contact of the second arrangement.
