Vapor phase soldering is commonly used in the fabrication of electronic cards fitted with module packages. This process makes use of solder fluxes which require removal with Dow Chemical Co.'s prelete solvent (A 7% aliphatic alcohol in 1,1,1-trichloroethane) or another chlorinated solvent. These solvents have a deleterious effect on various epoxy encapsulations used on first level modules. An alternate group of materials may be used for encapsulation to eliminate this problem.
