Abstract

PURPOSE:To prevent the peeling of a metallic case on the interface between the metallic case and an urethane resin and a phenomenon that the breaking and the expansion of the urethane resin are generated by a method wherein an epoxy denaturation phenol resin is interposed between the metallic case and the urethane resin. CONSTITUTION:A circuit board 1 mounted with a plurality of pieces of electronic components (surface mounting components) 2 and electronic components (components with leads) 2' is housed in a metallic case 4. Then, when an epoxy denaturation phenol resin 6 is poured in the case 4 to a prescribed height, said resin flows out gradually through apertures 7 and when the resin soon flows out to be run through, the resin is coated on the inner wall of the case 4 and the surface of the substrate 1 mounted with the components 2 and 2'. Then, when the resin 6 is cured at 120-150 deg.C for 30-60 minutes after being dried at 60-80 deg.C for 30-60 minutes in the interior of an oven, the resin 6 shuts the apertures 7. Then, an urethane resin 5 is encapsulated in the case 4 to a prescribed position and is cured at 80 deg.C for 2 hours.
