Method of encasing electric components

A method of forming an outer protective coating on an electric component of a type including a component body and at least one pair of lead wires extending outwardly therefrom in generally the same direction, said method comprising the steps of:

• first dipping the electric component into a solution of chlorinated hydrocarbon having dissolved therein a solute selected from the group consisting of aliphatic hydrocarbon and higher fatty acid, said dipping being carried out with the component body and only those portions of the lead wires adjacent the component body being immersed into the solution to form a film of the solute covering both the entire surface of the component body and the surfaces of those portions of the lead wires adjacent said component body;
• then dipping the electric component into a solvent with the component body partially immersed into the solvent to remove the film covering all surfaces of the component body except for those surfaces of the component body located adjacent the lead wires;
• and thereafter
• dipping the electric component into an insulative coating solution with both the component body and those portions of the lead wires adjacent said component body being immersed into the insulative coating solution to form an outer protective coating enclosing the component body therein.
