Claim:
1. A method of making an electronic assembly comprising: applying a reactive hot melt adhesive composition comprising an atmospheric curing prepolymer and a first thermoplastic component, the first thermoplastic component having a Mettler softening point of less than 120° C. to at least a portion of a first substrate, the atmospheric curing prepolymer being an aliphatic isocyanate terminated polyurethane prepolymer that is a reaction product of an aliphatic polyisocyanate and a polyol at an NCO/OH ratio of from about 4.0:1.0 to about 4.0:1.5, and contacting the adhesive on the first substrate with at least a portion of a second substrate, at least one of the first and second substrates comprising at least one electronic component prior to applying the adhesive composition, the electronic component being disposed between the first substrate and the second substrate the first and second substrates being of the same or different material and being independently selected from the group consisting of polyethylene, polyethylene terephthalate, polyethylene naphthalate, and mixtures thereof.
