ABSTRACT:
An adhesive material 220 including a fluxing agent and metal particles 240 is applied to either a substrate 200 having a metallization pattern 210 or an electrical component 230. The component 230 is positioned on the substrate 210 and heated. During the heating step, the fluxing agent promotes adhesion of the metal particles 240 to the substrate metallization pattern 210 and the component, and the adhesive material 220 is cured, to mechanically interconnect and encapsulate the substrate 210 and the component 230.
