    Abstract: A method of forming circuit interconnections between adjacent circuits of a multilayer circuit structure is described in which corresponding sets of solder protrusions carried on conductive tracks of adjacent circuits are separated by a layer of uncured, heat-curable insulating material having a transient state, in which the material becomes deformable, between the uncured and the cured states. The layer is heated and the circuits are urged towards one another during the transient, deformable state of the material so that the protrusions pierce the layer, corresponding protrusions contacting one another and the heat subsequently causing the material to become cured. Finally, the contacting protrusions are fused together.
